Dr James Heath, from Lancaster Environment Centre, said: “In terms of the temperatures, it’s worth noting that June 1970 didn’t see anything quite like the extremes that we saw this year – instead the temperatures were more consistently in the low to mid 20s for a substantial period, with a couple of hot days topping 27C.
“This year, for the first week or so, the warm temperatures were purely as a result of the long periods of strong sunshine under persistent high pressure.
“Then very warm air from the south arrived, giving us the record-breaking 30.1 C on June 12 – and the week from June 10 saw temperatures over 25C – the Met Office’s ‘heatwave’ threshold for this region - on six days out of the seven.

“The only day that saw a maximum temperature below the long-term average was Friday June 30.”
The total monthly sunshine hours for June have also beaten the previous record which was set in 1975.
James added: “Although a calendar month seems quite an arbitrary period of time, we can see quite clearly that incidences of high temperatures / heatwave conditions are becoming more frequent and extreme – therefore it is increasingly likely that these monthly records will be broken more frequently.”
