Exceptional Sunshine and Persistent Heat Across the UK
Several regions in the UK have experienced nearly double their typical July sunshine hours within less than two weeks amid an ongoing heatwave. This surge in sunshine has predominantly affected southern and south-west England, coinciding with a period of 10 consecutive days where temperatures have exceeded 30°C (86°F).
The heatwave has extended across the entire UK, impacting areas from southern England through Scotland, Wales, and Northern Ireland. Forecasts indicate that the heat is expected to intensify and sp broadly during the week. Although temperatures may decline slightly over the weekend, sunny conditions are anticipated to persist.
How Sunny Has It Been?
July has already proven to be an exceptionally sunny month. Locations such as Yeovilton in Somerset and Odiham in Hampshire have recorded approximately 152 hours of sunshine within the first 13 days, nearly twice the average for this period. This phenomenon is attributed to persistent high-pressure systems over the UK, which promote sinking air that suppresses cloud formation.
While some inland areas have experienced cloudy mornings, strong sunshine typically dissipates this cloud cover during the day. However, cloudiness can linger near the North Sea coasts.
In addition to abundant sunshine, July has been notably dry. Certain parts of England have recorded no rainfall so far this month. For example, Wisley in Surrey has experienced 27 consecutive days without precipitation. Rainfall levels in Wales and Northern Ireland have also been significantly below average.
Due to the ongoing dry conditions, more than eight million households in England are currently subject to hosepipe bans. The persistent dryness also maintains a heightened risk of wildfires.
Heatwave Intensifies
The peak of the UK's third heatwave this year occurred on Thursday 9 July and Friday 10 July, with temperatures reaching up to 35°C. Although temperatures have slightly decreased since then, some areas continue to experience daily highs of 30°C or above.
On Tuesday, the UK recorded its 10th consecutive day with temperatures reaching or exceeding 30°C in certain locations. Areas such as Teddington, Richmond upon Thames, Kew Gardens, and Heathrow in London have all surpassed this threshold.
A pronounced east to north-easterly wind has recently pushed the highest temperatures further west. As this wind diminishes, the heat is expected to sp widely, with forecasts predicting rising temperatures throughout the week. The heatwave threshold is anticipated to be met again in Scotland, Northern Ireland, and northern England.
Briefly Cooler Weekend
Temperatures are expected to fall slightly over the weekend due to a northerly wind as the high-pressure system shifts position. Maximum daytime temperatures will likely range from 22°C in Scotland and Northern Ireland to 28°C in southern England, which remains warm for this time of year.
This cooler period is expected to be brief, as high pressure is forecast to rebuild over the UK next week. This will likely result in rising temperatures across most regions, accompanied by continued dry conditions and strong sunshine.
