Forecasters are predicting the start of July will be filled with hot days and humid nights as warm weather in Spain, Portugal and France makes its way to the north of England.
On Sunday, the Met Office predicted that Barrow is set to see temperatures of up to 29 degrees this week.
A sweltering few days is due to be capped off with heavy downpours and possible thunderstorms on Thursday.
A Met Office spokesman said: “In contrast to June so far, which has seen temperatures often near or just below normal, next week could see a real change in the way it feels.
“It looks like heat will start to build across Iberia later this weekend and spread northwards across France early next week as a tropical continental airmass begins to dominate the weather.
“Temperatures across Iberia and southern France could reach the low 40’s Celsius by midweek with northern France seeing temperatures into the mid to high 30s Celsius.
“The UK is likely to be near the boundary between this tropical continental airmass and a tropical maritime airmass over the Atlantic, but we do expect to see temperatures rise across the whole of the UK for the start of July.
“As is traditional with hot weather in the UK in the summer it may end with thunderstorms.”
