This summer could end up being the UK’s hottest on record with the race for the top spot still “wide open” – despite the threat of a washout this weekend.
The Met Office said the mean temperature for this summer so far is 16.1C: exactly the same as it was at this point during the record-holding summer of 2006.
Whether 2018 beats the record could come down to a matter of tenths or even hundreds of difference in Celsius.
The final figure for summer 2006 was 15.78C – a fraction above the two years in second place, 2003 and 1976, which tied on 15.77C.
But even if 2018 misses out on topping the chart, the Met Office believes it is still likely to finish in the warmest top five.
This summer’s average maximum temperature could also end up a record-breaker.
At present the figure stands at 21.1C – ahead of the equivalent figure in 1976 (20.7C), which is the year that holds this particular record.
The Met Office says it “remains to be seen” whether the rest of August 2018 will be cool or warm, meaning it is “impossible to say” which year will end up as the record.
Dr Mark McCarthy, head of the Met Office National Climate Information Centre, said: “Looking at maximum temperatures might seem to chime more with our perceptions, as our memories tend to focus on those hot days when the temperatures really peaked, rather than the mild nights.
“However, by including night and daytime temperatures, the mean temperature measure gives a fuller picture of what the UK climate is doing.
“On this measure it’s clear that the meteorological summer of 2018 is exceptional, simply for the consistent levels of warmth seen throughout the period so far.”
Rainfall across the UK this summer is currently running at 54.0 per cent of the long-term average.
An average of 130.1mm has fallen over the country, which is already more than the total average for the whole of the famously dry summer of 1976 (104.6mm).
And the country is braced for more rain this weekend, with Scotland, Northern Ireland and northern England expecting showers.
There is a chance of rain in London and the South as well, but it won’t be as heavy as that in the north.
