UK Weather: Temperatures to soar to 29C this weekend as sunshine returns after week of rain
UK weather is set for a dramatic shift as temperatures are forecast to climb to 29C this weekend. Following a miserable period of heavy rain, sunshine is returning across the country, with reports indicating that a heatwave is becoming increasingly likely, particularly in London, as temperatures rocket.
Will the UK experience a heatwave this weekend?
Current forecasts indicate a significant warming trend, with temperatures expected to soar to 29C by the weekend. This surge follows a period of unstable weather, and while the immediate spike is confirmed, there is ongoing discussion regarding whether this is the start of a sustained heatwave. According to reporting from ITVX, there are questions as to whether another full-scale heatwave is currently brewing.
The transition to these warmer temperatures will not be instantaneous. Data from Sky News suggests that the lead-up to the weekend will feature a volatile mix of heavy rain and sunshine. This atmospheric instability is a precursor to the warmer air mass expected to settle over the UK, bringing a sharp contrast to the recent conditions.
Key Forecast Highlights:
- Peak Temperature: Expected to reach 29C this weekend.
- Immediate Outlook: A blend of sunshine and heavy rain throughout the week.
- Regional Intensity: London is highlighted as a primary area where a heatwave is “more likely.”
- Recent Context: A “miserable week” of persistent rainfall.
The transition from heavy rain to soaring heat
The upcoming spike in temperature is particularly notable because of the conditions that preceded it. The BBC has reported a return of rain to the UK immediately ahead of the predicted heatwave, extending a period that the London Evening Standard described as a “miserable week.”
This rapid swing from wet, cool weather to temperatures nearing 30C is a characteristic of the UK’s volatile climate. The current pattern shows a sequence where heavy rain clears to make way for high-pressure systems that allow sunshine to dominate and temperatures to rise quickly.
According to Sky News, the current week serves as a bridge between these two extremes. Residents can expect intermittent heavy showers and bursts of sun, a combination that often leads to humid conditions before the heat fully takes hold over the weekend.
Why London is more susceptible to the coming heat
While the temperature increase is a national trend, the impact is expected to be more pronounced in the capital. The London Evening Standard reports that a heatwave in London is “more likely” within days, with temperatures predicted to rocket.
This regional disparity is often driven by the urban heat island effect, where concrete and asphalt in densely populated cities absorb and retain more heat than rural surroundings. When national temperatures hit the 29C mark, urban centers like London frequently experience higher localized peaks, increasing the likelihood of the conditions meeting the official threshold for a heatwave.

Analyzing the “miserable week” vs. the weekend surge
The contrast in the weather outlook is stark. For several days, the UK has dealt with persistent rainfall and low temperatures, creating a damp environment across most regions. The shift to 29C represents a significant atmospheric pivot.
The transition can be summarized as follows:
- Phase 1 (The Miserable Week): Characterized by consistent rain and a lack of significant warmth.
- Phase 2 (The Transition): A volatile mix of sun and heavy rain, as reported by Sky News.
- Phase 3 (The Weekend Peak): Rapid warming leading to a peak of 29C, with sunshine returning.
This sequence of events often leads to increased humidity, as the returning sunshine evaporates the moisture left behind by the “miserable week” of rain. This can make the 29C temperature feel more oppressive than it would in a drier climate.

Potential implications of the temperature spike
A jump to 29C after a period of heavy rain has several immediate implications for the public and infrastructure. The sudden return of sunshine often leads to a surge in outdoor activity, putting pressure on public spaces and transport networks, particularly in London where the heatwave likelihood is higher.
From a health perspective, rapid temperature swings can be challenging for vulnerable populations. The shift from rain-cooled air to near-30C heat requires quick adaptation. The “rocketing” nature of the temperature increase mentioned by the London Evening Standard suggests that the warming will happen over a short window, rather than a gradual climb.
Furthermore, the preceding heavy rain may lead to increased humidity levels. When high temperatures meet saturated ground, the resulting “muggy” feel can amplify the perceived heat, making 29C feel significantly warmer than the thermometer suggests.

Common misconceptions about UK heatwaves
One common misconception is that a few days of high temperatures automatically constitute a “heatwave.” While ITVX is questioning if a heatwave is “brewing,” a true heatwave typically requires a specific duration of high temperatures. The current forecast for 29C this weekend is a significant spike, but whether it sustains the criteria for a formal heatwave remains to be seen.
Another misunderstanding is the belief that rain immediately cools the air for the long term. As the BBC reports, rain often returns *ahead* of a heatwave. In many cases, the clearing of a rain-bearing front is exactly what allows warmer, drier air from the south to move in and push temperatures upward.
Frequently Asked Questions
What is the maximum temperature expected this weekend?
According to The Independent, temperatures are expected to soar to 29C this weekend as sunshine returns.
Will it rain before the heat arrives?
Yes. The BBC reports that rain is returning to the UK ahead of the predicted heatwave, and Sky News expects a mix of heavy rain and sun throughout the week.
Which areas are most likely to experience heatwave conditions?
The London Evening Standard indicates that a heatwave is “more likely” in London, where temperatures are expected to rocket.
Has the UK had good weather recently?
No. Multiple sources, including the London Evening Standard, describe the preceding period as a “miserable week” characterized by rain.
Is this a long-term heatwave or a short spike?
While the weekend peak of 29C is forecast, ITVX reports that it is still being determined whether a broader heatwave is brewing or if this is a temporary surge.
