As much of Britain continues to bask in scorching conditions, weather watchers are waiting to see if tomorrow will bring the hottest October day on record.
Meteorologists say it is unlikely the 26-year-old October record of 29.4C (84.9F) will be bettered but many will be glued to their thermometers as temperatures are set to close in on this figure.
The record dates back to October 1, 1985, at March in Cambridgeshire.
The final round-up of yesterday’s highs left Kew Gardens in west London as the UK’s hot spot with a temperature of 28.8C (83.8F). This was highest ever September 29 temperature, beating a record set in York in 1895 when the thermometer reached 27.8C (82F).
Stephen Davenport, forecaster for MeteoGroup, the weather division of the Press Association, said today looks likely to be the hottest September 30.
He said: “Potentially we’re looking at 28C and 29C again today. That would make it the hottest September 30.
“Whether we will break the record tomorrow - there’s a chance, but it’s probably less likely.
“East Anglia and the South East are going to get the highest temperature but it should be hot over a large part of the country.”
Mr Davenport said the weather is likely to stay warm until the beginning of next week when it will probably begin to cool.
He said some areas of the UK were already missing out on the record temperatures.
Northern Ireland was covered in cloud today, although still feeling quite warm.
In Scotland, rain was threatening the north west and could move down as far as northern areas of England.
Sun-seekers were continuing to enjoy the unusual heatwave on beaches and in parks across the UK.
Last night Network Rail said there were some temporary speed restrictions in place over short stretches of track because of the heat.
A spokeswoman said: “There are no significant delays to any passenger services today owing to the warm weather.
“At a small number of locations there are temporary speed restrictions in place over short stretches of track but these will have little impact, if any, on journey times.”
