After Britons experienced the hottest May on record last month, the first week of June saw lows of 6°C with temperatures only just peaking at 16°C.
Noting that the weather was “perfectly normal” for the time of year, Professor David Schultz from the University of Manchester said the reason for recent colder temperatures was because “the jet stream is farther south than normal for this time of year” and is “bringing cooler drier air from the north-west over the UK”.The jet stream is an area around 5km to 10km up into the atmosphere where fast winds travel at speeds of around 100mph.
“We’d expect, particularly at this time of year, for it to be going north of the UK – almost in the diagonally opposite direction from where we’d expect it to be going.”
