The Spring bank holiday lands on Monday 25 May 2026, three weeks and change away from today. It is the second of two May bank holidays, the unofficial gateway to summer, and the long weekend that traditionally signals the start of camping, festival, and beach season for a lot of UK households. It is also, in my experience watching the forecast for these things every year, the bank holiday with the widest weather range. I have seen a 26C scorcher and a 9C wash-out land on the same calendar slot in consecutive years.
This guide pulls together what late May has historically delivered, what is realistic to expect this year, and how to plan a long weekend that survives whatever the jet stream decides to do.
When Is the Late May Bank Holiday 2026?
The Spring bank holiday is the last Monday of May every year. In 2026 that is Monday 25 May, giving most workers a Saturday-to-Monday three-day weekend from 23 to 25 May. It applies in England, Wales, Scotland, and Northern Ireland.
This is a different bank holiday from the early May one on Monday 4 May 2026, which we covered in our May bank holiday 2026 weather guide. The late May one is warmer, longer in daylight, and historically a notch drier in the south. It also coincides with RHS Chelsea Flower Show week (19 to 23 May 2026), the Whitsun school half term in most of England and Wales, and the start of the festival season.
How Late May Compares to Early May
The two May bank holidays are only three weeks apart, but the weather typically shifts noticeably between them.
| Metric | Early May (4 May) | Late May (25 May) |
|---|---|---|
| Average UK high | 13 to 17C | 15 to 19C |
| Average UK low | 5 to 9C | 7 to 11C |
| Daylight hours | 15 to 16 | 16 to 17 |
| Sea temperature (south coast) | 11 to 12C | 13 to 14C |
| Average rainfall (UK) | 10 to 30mm | 8 to 25mm |
| Pollen risk | Tree peak, grass starting | Grass season ramping hard |
By late May, the land has had another three weeks of strong sunshine, the seas are noticeably warmer, and convective showers are less ferocious than in April. It is also the first bank holiday of the year where a beach trip can feel genuinely summery rather than aspirational.
Historical Weather for the Spring Bank Holiday
Met Office climate averages for the last week of May, drawn from the UK climate averages dataset, give a clear regional picture.
Temperature
Average daytime highs and overnight lows for the last week of May.
| Region | Average High (C) | Average Low (C) | Typical Feel |
|---|---|---|---|
| Southeast England | 17 to 19 | 8 to 11 | Warm, summery in sun |
| Southwest England | 16 to 18 | 8 to 10 | Mild to warm |
| Midlands | 16 to 18 | 7 to 10 | Mild to warm |
| East Anglia | 16 to 19 | 7 to 10 | Warm, often dry |
| North England | 14 to 17 | 6 to 9 | Mild |
| Wales | 14 to 17 | 7 to 10 | Mild |
| Scotland (Lowlands) | 13 to 16 | 6 to 9 | Cool to mild |
| Scotland (Highlands) | 11 to 14 | 4 to 7 | Cool, fresh |
| Northern Ireland | 14 to 16 | 6 to 9 | Mild, often cloudy |
These are averages. Recent late May bank holidays have ranged from a barely double-figure 12C to over 26C in the southeast, so do not pack as if the table is a guarantee.
Rainfall
Late May rainfall is typically lower than April or early May across most of the UK. Southern and eastern England average around 8 to 15mm in the last week of May, with the western Highlands and Snowdonia closer to 25 to 35mm. The rain that does fall is usually convective, which means short, sharp showers rather than all-day drizzle.
For a deeper take on how convective showers work, see our will it rain today guide and April showers explained.
Sunshine
Daylight is long. Sunrise on 25 May 2026 is around 04:55 in London and 04:35 in Edinburgh, with sunset around 21:05 and 21:35 respectively. That is more than 16 hours of daylight in the south and over 17 hours in northern Scotland. Average sunshine for the last week of May is roughly 6 to 8 hours per day in southern and eastern England, dropping to 4 to 6 hours in the north and west.
Recent Spring Bank Holiday Weather
Looking back at the last five Spring bank holidays helps calibrate expectations.
| Year | Date | Conditions | Notes |
|---|---|---|---|
| 2025 | 26 May | Warm, mostly dry south | Highs of 22 to 24C in the southeast, cooler and showery in Scotland |
| 2024 | 27 May | Cool, unsettled | Showers across much of the UK, highs only 14 to 17C |
| 2023 | 29 May | Warm, sunny | A widely fine bank holiday, 23 to 25C across much of England |
| 2022 | 2 Jun (Jubilee) | Mixed | Spring bank holiday moved to mark the Platinum Jubilee, showers in places |
| 2021 | 31 May | Warm, dry | Highs near 25C in southern England, dry across most of the UK |
The pattern across these years: late May tilts dry and warm in the south more often than not, but a chilly, showery bank holiday is still well within the normal range. There is no "always sunny" or "always wet" rule.
What Influences Late May Weather
Three factors do most of the work.
The Jet Stream Position
If the jet stream sits north of Scotland by late May, high pressure builds over the UK, and warm continental air drifts up from France and Spain. That is the pattern that gives us 25C plus bank holidays. If the jet sags south across the British Isles, low-pressure systems queue up off the Atlantic and the bank holiday turns showery. By 25 May the jet has usually weakened compared to winter, but it can still drag a band of rain across us in 24 hours.
For the mechanics, see our UK weather patterns explained guide.
Continental Heat Plumes
Late May is the first window of the year where a Spanish or French heat plume can push north across the UK. When it happens, southern England can see 26 to 30C, sometimes for a single dramatic day before a thundery breakdown. The 2024 Whitsun bank holiday missed it; 2018 caught one and recorded 28C in Northolt.
Sea Temperatures
By 25 May, UK coastal waters are typically 12 to 14C, warmer in the southwest and around the Channel Islands. That is still cold for swimming, but warm enough that a sea breeze does not always cap inland temperatures the way it does in April. Coasts can still feel five degrees cooler than inland on a sunny day.
Regional Outlook for 25 May 2026
Specific forecasts for the bank holiday will not become useful until around Wednesday 20 May. Until then, here is what each region typically delivers and where to focus your fallback planning.
Southern England
The most likely region to see a warm, dry bank holiday. Expect highs of 17 to 19C as a baseline, with a real chance of 22C plus if a southerly airflow develops. Coastal areas can feel cooler when winds are onshore. If you are planning a beach day, our best UK beaches weather guide helps with the right pick.
Midlands and East Anglia
Similar temperatures to the south, often a touch drier in East Anglia thanks to the rain shadow of higher ground to the west. The Midlands can catch isolated showers when westerly fronts push through.
Northern England
Cooler than the south, with highs of 14 to 17C. The Lake District and Pennines pick up more rain. The east coast, Yorkshire and Northumberland, can be drier but cool when the wind has any easterly component.
Wales
A west and east split. Snowdonia and west Wales catch most Atlantic rain. East Wales and the Wye Valley are usually milder and drier. For walking, see our best UK spring walks guide.
Scotland
The biggest spread. The west Highlands can be wet and breezy while Edinburgh and Aberdeen sit dry under the same broad pattern. Highs of 13 to 16C in the Lowlands, cooler in the Highlands. Frost in sheltered glens is rare but not impossible by 25 May.
Northern Ireland
Mild, often cloudy. Highs of 14 to 16C. Western counties pick up more drizzle. Eastern counties around Belfast often see brighter spells.
When to Trust the Forecast for 25 May
Forecast skill drops sharply with lead time. Our how accurate are weather forecasts guide covers this in detail, but the short version for this bank holiday:
- Today, 1 May: Long-range outlooks are signal not detail. Useful for spotting "warmer than average" or "wetter than average" trends, not for planning a barbecue.
- Around Monday 18 May: Models will have a confident fix on the broad pattern. Trust this for "warm or cool, dry or showery".
- From Wednesday 20 May: Day-by-day timing of any rain or sunshine becomes reasonably reliable.
- Friday 22 May onwards: Hour-by-hour forecasts for the bank holiday weekend are usable for actual plans.
The Met Office forecast and BBC Weather are both worth checking; if they disagree by more than a few degrees, the atmosphere is genuinely uncertain.
What to Do Over the Long Weekend
Late May is one of the best weekends in the UK calendar if you want to be outside.
- Camping or glamping. Sea temperatures are still cold but campsite ground is dry, midges have not yet peaked in Scotland, and overnight lows are usually in single digits, not freezing.
- Coastal walks. Cliffs are at their floral peak: thrift, sea campion, and bluebells in shaded coombes. The South West Coast Path, the Pembrokeshire Coast Path, and the Norfolk Coast Path are all in their sweet spot.
- Garden visits. National Trust and English Heritage gardens are at peak rhododendron and azalea. Sissinghurst, Bodnant, Stourhead, and Mount Stewart are particularly good in late May.
- Festivals. The first big outdoor festivals of the year are clustered around Spring bank holiday weekend.
- Cricket and cycling. County cricket and Sunday club rides both work on a typical late May day.
If the forecast turns wet on Friday 22 May, indoor backups are easier to book than at Easter because cathedrals, art galleries, and city museums are quieter than peak summer.
Pollen Warning for Late May
Late May is the worst week of the year for many UK hayfever sufferers. Grass pollen, which affects roughly 95% of UK hayfever sufferers according to Allergy UK, typically ramps from mid-May and peaks in early to mid-June. Tree pollen is mostly past its peak by 25 May, but oak and pine can still bother some people.
Practical tips for the bank holiday:
- Check pollen forecasts the night before. Counts above 'medium' are usually enough to trigger symptoms in sensitive people.
- Take antihistamines a day or two before, not on the morning of, for the best effect.
- Showers and a change of clothes after a long walk make a noticeable difference.
- Coastal trips usually have lower pollen counts than inland; sea breezes flush the air.
Our UK pollen season 2026 guide has the full month-by-month picture.
What to Pack
Late May still demands layering, but the balance shifts compared to early May.
- A t-shirt and a light long-sleeve, plus a fleece or jumper for evenings
- A waterproof shell for any walking longer than an hour
- Sun cream, factor 30 minimum: late May UV in the UK can hit 6 or 7
- Sunglasses; the sun is high and bright by 11am
- A compact umbrella for towns; a proper waterproof for hills
- Walking shoes or trainers that handle a wet path; light hiking boots for upland routes
- A water bottle: warm sunshine surprises people who packed for April
If camping, an extra blanket is worth more than an extra fleece. Clear nights in late May still drop to 4 or 5C in low-lying valleys.
Festivals, Events, and the Weather Risk
Several major UK events fall in late May. For each, the weather risk is worth a separate thought.
| Event | Dates 2026 | Weather risk |
|---|---|---|
| RHS Chelsea Flower Show | 19 to 23 May | Mostly indoor pavilions, but outdoor gardens and queues are exposed |
| Hay Festival | 21 to 31 May | Outdoor village setting in Powys; bring waterproofs |
| Bath Festival | Late May | Mix of indoor and outdoor; rain rarely a deal breaker |
| Cheltenham Jazz | Late April to early May | Tented venues; comfortable in a normal late spring |
Tickets are non-refundable for nearly all of these, so the realistic plan is to dress for two scenarios and accept that one tent slot might be muddy.
Frequently Asked Questions
What is the weather forecast for the late May bank holiday 2026?
It is too early for a precise forecast. Reliable day-by-day predictions become available from around Wednesday 20 May 2026. Based on historical averages, expect daytime highs of 14 to 19C across the UK, with the south often warmer and the chance of a 22C plus warm spell if pressure builds. Check the Met Office forecast closer to the date.
When is the Spring bank holiday 2026?
The Spring bank holiday, also called the late May bank holiday or Whitsun bank holiday, is on Monday 25 May 2026. It is the last Monday of May.
Is the late May bank holiday usually warmer than the early May one?
Yes. Average daytime highs are typically 2 to 3C warmer in the last week of May than in the first. Sea temperatures are about 2C warmer too, and daylight is roughly 45 minutes longer, which makes outdoor plans more flexible.
Will it rain on the Spring bank holiday 2026?
Statistically, late May has a slightly lower chance of rain than early May, with around 35 to 45% of bank holidays seeing measurable rain in the south, rising to 55 to 65% in the northwest. Showers, if they occur, tend to be sharp and short rather than all-day rain.
What is the difference between Spring bank holiday and Whitsun?
Whitsun, or Whit Monday, was historically the Monday after Pentecost in the Christian calendar. It was replaced by the fixed Spring bank holiday in 1971. Many people still call the late May bank holiday "Whitsun bank holiday" out of habit.
Is late May good for UK beach trips?
Yes, with caveats. Air temperatures are typically 17 to 19C in southern coastal towns, sea temperatures 13 to 14C. The sea is still cold for swimming without a wetsuit, but rock pooling, paddling, and beach walking are pleasant. The southwest, the south coast, and the Channel Islands are usually the best picks.
Can I rely on long-range forecasts for 25 May?
Not for detail. Long-range outlooks released today, 1 May, can hint at "warmer than average" or "drier than average" but cannot reliably tell you whether 25 May itself will be wet. Wait until around 20 May for a usable day-by-day forecast.
The Honest Read for 1 May 2026
The Spring bank holiday on Monday 25 May 2026 is, on the balance of probabilities, more likely to be a good weekend than a bad one. Long daylight, mostly low rainfall, and rising temperatures all sit in your favour. The risk is a stalled low-pressure system or a cool northerly airflow, both of which can pull temperatures back into the early teens for a few days at a time.
The best plan is the same plan that works for every UK bank holiday. Pencil in two outdoor options and one indoor backup. Pack layers and a waterproof. Check the forecast properly from 20 May onwards. And on the day, before you head out, ask the only question that really matters.
