Mean temperatures hit 15.2ºC (59ºF) which is 0.8ºC above the average, according to the estimates covering June 1 through to August 28.
In terms of rainfall, the estimate suggests about 7.45in of rain - which is 78% of the UK average, making this the driest summer since 2006 and ranking about 16th driest in the records dating back to 1910.
In 2006, the UK enjoyed mean temperatures of 15.78ºC (60ºF), 7.4in of rainfall and 601.5 hours of clear sunshine that was not blocked by any cloud.
This summer there was an above average 588 hours of sunshine in the UK making it the seventh sunniest in the records going back to 1929, the Met Office said.
"It's likely this summer will finish around eighth to 10th warmest in the national record dating back to 1910," a Met Office spokesman said.
"While this summer is warmer, drier and sunnier than the long-term average, it hasn't been exceptional. It stands out because the last six summers have been wetter than average, with 2012 and 2007 both being in the top five wettest, and 2008 and 2009 also in the top 10 wettest in records from 1910.
"This summer also contrasts with the rather cool summers of 2011 and 2012."
The most striking memory of this summer may be the 19-day heatwave in July which was "more notable for its duration than the actual temperatures recorded", according to the spokesman.
The UK was also bathed with spells of warm and settled weather in June and August - with the highest temperature of the year, 34.1ºC (93ºF) recorded on August 1 at Heathrow. This was the highest UK temperature since July 2006. For south-east England and East Anglia this will be the driest summer since 1995.
There were also some very wet days in parts of the UK. Torrential rain on July 23 caused flash flooding in Scotland, Nottinghamshire and in parts of Northern England and.
Heavy rain caused some flooding in Essex on August 24, it was also noted.
