The Met Office said the uk weather forecast heatwave will not arrive evenly, with the country splitting from Thursday, June 18 between cloudier, wetter conditions in the northwest and hot, humid weather in the southeast. The forecast also pointed to thunderstorms in the southeast as temperatures rise.
June 18 Forecast Split
People in the northwest and west were told to expect cloudier skies and heavy, breezy downpours. The southeast was forecast to face rising temperatures and high humidity, with the Met Office saying, “Given the potential for high temperatures and high humidity, there is the possibility of some thunderstorms breaking out as well.”
The forecast used a regional split rather than a nationwide pattern. For readers in the southeast, that means the main pressure point is not just warmth but moisture in the air, which can make the spell feel more intense than the temperature alone suggests.
End Of June Humidity
The intense humidity was expected to linger towards the end of June. That keeps the warmer pattern in place after the first change on June 18, with the southeast carrying the sharper risk of thunderstorms while the northwest stays under cloudier, breezier rain.
For anyone planning around outdoor work, travel, or events, the practical issue is that the forecast is not a single-conditions story. One part of the UK is set for downpours, while another moves into hotter, stickier air.
Met Office Late July Outlook
Between Sunday, June 28 and mid-July, the Met Office expected largely settled and dry conditions across the UK. Temperatures would likely be above normal, with the potential for hot conditions to develop, especially in the south.
By mid-July, temperatures were expected to ease back closer to normal, although warm and humid spells could still occur. As July progressed, the high-pressure system was predicted to weaken and allow unsettled weather and thunderstorms to return to the south again.
