Brits are being urged to dig out their fans and prepare for sticky sleepless nights as the Met Office warns of a massive spike in humidity. Forecasters have advised that the UK is about to be hit by rising temperatures, with “high humidity,” explosive thunderstorms and heavy downpours expected in some parts of the country.
According to the weather agency’s latest long-range forecast, there will be a split in conditions between the north west and south east from Thursday, June 18.
Those living up north and out west can expect a rather miserable affair, with “cloudier” skies and heavy, “breezy” downpours. But for millions of Brits further southeast, the weather is about to turn into a full-blown tropical sweatbox.

The Met Office said: “Given the potential for high temperatures and high humidity, there is the possibility of some thunderstorms breaking out as well.”
The muggy misery isn’t going anywhere fast, either. Experts say the intense humidity will linger towards the end of June, making conditions feel incredibly close and uncomfortable.
Thankfully, the damp and dreary split should clear up just in time for July, as a massive wall of high pressure moves in to dominate the UK.

Between Sunday, June 28 and mid-July, the weather gods are finally expected to bring “largely settled and dry conditions” across the board. But don’t get too comfortable, because the heat is about to get cranked up to the max.
The Met Office added: “Temperatures will likely be above normal, with the potential for hot conditions to develop, especially in the south.”
However, in true British summer fashion, the scorching heatwave looks set to break in spectacular style.
As we roll deeper into July, the protective high-pressure bubble is predicted to weaken, opening the floodgates for “unsettled weather and thunderstorms” to strike the south once again.
While temperatures are expected to “ease back closer to normal” by mid-July, forecasters have warned that “warm and humid spells remain possible at times,” meaning the sweaty, muggy conditions could haunt us well into the summer.
