'This summer from June to August is reportedly set to be a perfect time to take a staycation - thanks to a weather pattern called the North Atlantic Oscillation (NAO), which is seeing a shift in its four-year negative phase that will allow warm air to push through.
Dr Todd Crawford of Weather Services International told the Express: "As we head into the summer period, we expect a distinctly different pattern to what we have observed over the last four years.
"Since the factor that drove the negative NAO for the last four years are no longer in place, we expect a much warmer, drier summer in the UK this year, more similar to the summers observed during the 2002 to 2006 period."
Back in 2006, Britain enjoyed its hottest summer for 500 years, with the mercury hitting 101.3F (38.5C).'
I knew there was an O in it 
& I remember 2006 now - we were on holiday in Norfolk & it was so hot I nearly passed out at the zoo
