As Britain's restless autumn skies briefly settle, a returning warmth — temperatures nearing 26°C in the south-east — offers the feeling of a borrowed summer. Yet the same high pressure that stills the winds and lifts the mercury also withholds the rain that parched landscapes desperately need. In a year already rewriting the record books for warm days, this welcome interlude arrives as a reminder that comfort and consequence are rarely separate.
UK braces for late summer warmth as temperatures peak at 26C next week
The warmth comes in a year already marked by records
Mark
So we're getting a warm spell next week—that sounds pleasant enough. What's the catch?
Mimi
The catch is that the same system bringing the warmth is also keeping the rain away. High pressure means dry conditions, and England and Wales are already in drought.
Mark
How serious is the drought right now?
Mimi
Serious enough that places like Leconfield have only received 11 percent of their normal September rainfall by mid-month. They should be at 50 to 60 percent by now.
Luke
But wait—the source says recent rain has been welcome. So there has been some rain. How much is "well short"?
Mimi
Recent rain has helped, but it hasn't been enough to meaningfully restore water storage. The deficit is still large.
Mark
And this warm spell—how long will it last?
Mimi
For England and Wales, possibly all week. For Scotland and Northern Ireland, it might be shorter-lived.
Luke
The source mentions forecasts are divided on what happens late week. So we don't actually know if rain returns or if the high pressure holds?
Mimi
That's right. Some models show rain returning late week into next week. Others show the high pressure persisting, potentially with even warmer air. It's genuinely uncertain.
Mark
So the drought could get worse?
Mimi
If the high pressure holds and rain doesn't return, yes. The warmth and continued dryness would deepen the problem.
Luke
One more thing—the source mentions 2026 has already broken records for days above 25 degrees. Is that unusual?
Mimi
Very. Last week alone exceeded the previous record of 89 days set in 1959. We're in unusual territory.
Der Puls
- Temperatures in southern England could reach 25–26°C next week — well above what late September should feel like — as high pressure builds across the country after days of blustery Atlantic disruption.
- The very system delivering the warmth is also locking out rainfall, tightening the grip of a serious drought across England and Wales at a moment when some stations have received barely a tenth of their normal September rain.
- 2026 has already shattered records for days above 25°C, surpassing the previous all-time mark of 89 days set in 1959 — and this coming warm spell will push that figure further still.
- A weather front edging into western Scotland midweek may bring some relief to the north, but southern regions look set to remain dry, leaving reservoir levels and water restrictions under mounting pressure.
- Forecasters are split on what follows: some models show rain returning late in the week, others suggest high pressure holds firm — a division that carries enormous practical weight for water managers and drought-affected communities.
As Britain's restless autumn skies briefly settle, a returning warmth — temperatures nearing 26°C in the south-east — offers the feeling of a borrowed summer. Yet the same high pressure that stills the winds and lifts the mercury also withholds the rain that parched landscapes desperately need. In a year already rewriting the record books for warm days, this welcome interlude arrives as a reminder that comfort and consequence are rarely separate.
Britain's week of unsettled, blustery weather is about to give way to something calmer and considerably warmer. High pressure will build across the country next week, lifting temperatures into the mid-20s across England and Wales — with the south-east potentially reaching 26°C — in what will feel, at least briefly, like summer's return. Saturday will still bring Atlantic gales along western coasts and patchy rain across the south, with warm, humid air drifting in from the mid-Atlantic. By Sunday, conditions will begin to settle, leaving most of the country dry and sunny by afternoon.
The change is driven by a buckling in the jet stream. Where it had been roaring straight across the Atlantic — pushing low pressure and rain to the north and strong winds across the middle — it is now beginning to bend, allowing high pressure to establish itself more widely. Into the early part of next week, sunshine will spread, humidity will rise, and by Tuesday some areas of England and Wales may wake to mist and fog before the warmth breaks through.
This warmth arrives in a year already marked by records. 2026 has seen more days above 25°C than any year previously measured, with last week alone pushing past the old record of 89 days set in 1959. But the same high pressure responsible for those sunny skies is also keeping rain away — and for a country in the grip of drought, that matters deeply. Rainfall across England and Wales is critically short: one East Yorkshire station had received just 11 percent of its normal September total by Friday morning; Durham had managed only 14 percent.
A weather front moving into western Scotland midweek may bring some rain to northern areas, but the south looks likely to remain dry and warm. Forecasters are divided on what follows — some models point to rain returning late in the week, others suggest high pressure holds or even strengthens. For those watching reservoir levels and water restrictions, the gap between those two futures is anything but abstract.
The changeable weather that has unsettled Britain for the past week is about to give way to something more settled—and warmer. Next week, high pressure will build across the country, bringing temperatures that could reach 26 degrees Celsius in the south-east and climb into the low 20s across much of England, Wales, Northern Ireland, and eastern Scotland. For many, it will feel like summer has returned, at least briefly. But the same weather system that brings the warmth will also bring something less welcome: continued dry conditions that will deepen an already serious drought across large parts of the country.
The weekend itself will remain unsettled. Saturday will see blustery Atlantic winds and gales along western coasts and hills, with a mix of sunshine and passing showers across many areas. Southern England and Wales will be cloudier, with rain or drizzle, particularly in the south-west. Despite the cloud cover, it will feel warm and humid as south-westerly winds pull warm, moist air from the mid-Atlantic. By Sunday, the weather will begin to settle. Early rain in the far north and south should clear, leaving most of the country dry with sunny spells by afternoon. Temperatures will drop closer to the seasonal average of 15 to 21 degrees Celsius, though strong winds in north-east Scotland will ease.
The shift happens as the jet stream, which has been driving the changeable conditions, begins to buckle. That brisk, straight jet stream roaring across the Atlantic has been responsible for the pattern of rain-bearing low pressure to the north, high pressure to the south, and strong winds in between. As it starts to bend, the weather calms.
Into next week, high pressure will establish itself more widely. Apart from early rain in Scotland and northern England, most places will see increasing sunshine. Temperatures will climb a degree or so from Sunday, and humidity will creep upward. On Tuesday, that combination of humid air and light winds across England and Wales could mean some areas wake to mist and fog. Once the sun breaks through, the warmth will be noticeable. The south-east could reach 25 or 26 degrees. This warmth comes in a year already marked by records: 2026 has already seen more days above 25 degrees than any year on record, with last week alone exceeding the previous record of 89 days set in 1959.
But the warmth comes with a cost. The same high pressure that brings the sunshine will keep rain away, particularly from the south. A weather front moving into western Scotland midweek may bring some rain and could develop into a low pressure system that spreads rain across the northern half of the country. However, southern areas are likely to remain largely dry and warm through the rest of the week. For a country struggling with drought, this is not good news.
Rainfall across England and Wales remains critically short of what is needed to break the drought. By Friday morning, Leconfield in East Yorkshire had received only 11 percent of its normal September rainfall. Durham had managed just 14 percent. Both figures fall well short of the 50 to 60 percent that would typically have fallen by this point in the month. Recent rain has provided some relief, but it has been nowhere near sufficient to restore water storage levels to healthy levels.
Forecasters remain divided on what comes next. Some models suggest rain could return more widely from late in the week and into the following week. Others point to high pressure holding firm, with the possibility of even warmer air moving in. For those watching reservoir levels and water restrictions, the difference between those two scenarios matters enormously.
