Britons are being warned to stay out of the sun between now and Friday as the Met Office had issued an amber heatwave alert.
The warning is in place until 9am on Friday for parts of England as scorching temperatures are expected to rise further.
Official guidance is to stay out of the sun and keep homes as cool as possible, shading windows and shutting them during the day.
The amber, or level three, warning is issued when temperatures are predicted to hit 30C (86F) during the day, and 15C (59F) at night for at least two consecutive days.
The Met Office forecasts “very hot” weather in east and southeastern areas, with long spells of sunshine ranging from “very warm” to “hot and humid” in the West and East Midlands.
There will also be “very warm and muggy overnight conditions”, it says.
The balmy conditions could continue well into August, staying mostly hot for the rest of the month.
Sky’s weather producer Chris England says: “It’s quite a long time to August in weather forecasting terms, but it doesn’t look like things are going to change that much from the last few weeks.
“Will we beat the UK record temperature of 38.5C recorded at Faversham in Kent on 3 August 2003? It’s too early to say.”
The heatwave has also gripped much of Europe, with extreme heat affecting farmers in Poland, Sweden and Finland.
Sweden is seeing its hottest summer for a century, and temperatures in Finland have comfortably outstripped their typical highs of 18C (64.4F), reaching 30C in places.
Britons are advised to take precautions during the heatwave, including staying out of the sun during the hottest times (11am to 3pm), wearing sunscreen and staying hydrated.
Britain could have its hottest day of the year by the middle of the week as forecasts suggest temperatures could reach 33C (91.4F) or 34C (93.2F).
Some showery rain is possible – mainly in the North and West – but Wednesday and Thursday have the potential to break records.
Porthmadog in Wales is currently the record-holder for the year – where it hit 33C (91.4F) on 28 June.
