UK set for first 30C 'mega heatwave of year' with summer finally starting

The UK is on the cusp of its first 'mega heatwave' of the year - as summer finally starts. Temperatures that feel like 30C could bake Britain later this month, according to fresh weather maps and charts from meteorological agencies like Netweather.

As well as Netweather, WX Charts - which uses Met Desk data - has published projections showing an uptick in temperatures and the mercury from late June. The sixth month of the year will finally warm up before July arrives, forecasters say.

Ventusky says the temperature will "feel like" 30C in the south of England, particularly Somerset, on June 27. Looking ahead to June 20 to June 29, the Met Office has issued a forecast for the medium-term and long-term, with a separate outlook for June 30 to July 14.

"Initially fine conditions will likely prevail for most, with more changeable conditions with cloud and some rain being confined to the far north and northwest, temperatures will likely be close to or slightly above average," the Met Office went on to say.

"However, there is a small chance of an alternative scenario that initially an area of cloud could edge northwestwards from Europe and bring a couple of days of thundery rain and fairly hot / humid conditions to the southeast," the Met Office added.

The team at the forecasting agency continued, saying: "Into the last week of June, changeable conditions are likely, with the focus for these conditions being across the north and west, with spells of more settled and drier conditions likely in the south and east."

The Met Office added: "Nationwide, temperatures are expected to be close to or slightly above average." Exacta Weather's James Madden said: "Additionally, we could also see a very hot and extensive period of warmth developing within around this same mid- to late-month period (June), which could see temperatures topping out at something much higher than this at the peak of any heat event around this time."
