British Isles weather, July 2021

The 28th was cooler, and very showery, with widespread thunder over England and Wales away from the most southerly districts. A fire broke out at Trafford General Hospital in Greater Manchester after it was struck by lightning during heavy thunderstorms. Fire crews were called to the hospital at 1320 GMT after the fire began in the two-storey building. Rescuers say two women are "very lucky" to be alive after they were hit by lightning on the summit of Snowdon, Wales' highest mountain. The pair were in a five-strong group by its 1085 m peak when they were struck just after 1230 GMT. (Holbeach 23.C, Lerwick 13.0C maximum, Banagher Caugh Hill 9.1C minimum, Aldergrove 50.0 mm, Guernsey Airport 9.2.h.)

On the 29th many places were dry with sunny intervals, but there were areas of rain over NE Scotland, parts of NW England - and the SW peninsula, where it became windy during the evening as the early effects of Storm Evert were noticed. Temperatures were mostly not far from normal. (Heathrow 23.3C, Loch Glascarnoch 13.3C maximum, South Newington 7.3C minimum, Altnahinch Filters 21.0 mm, Heathrow, Manston and Shoeburyness 10.4 h.)

On the 30th storm vert moved NE'wards across S and Cent areas of England and Wales; there were outbreaks of rain that spread NE'wards across Ireland, England and Wales, with some thunder over the NE Midlands and Lincolnshire for a time in the afternoon. It became somewhat drier and brighter during the day in the S, but was breezy here. Scotland and Northern Ireland were mostly cloudy with some showers. It was generally chilly. A coastguard rescue helicopter airlifted people from at least four yachts off SW England today, and there were also reports of fallen trees blocking some roads in Cornwall. Some campsites had relocated guests to try to protect them against the elements, while others were prompted to pack up and leave. The highest gusts were on the Isles of Scilly at 69 mph; Bryher Campsite on the Isles of Scilly was forced to move some campers into a community hall overnight. (Weybourne 21.3C, Emley Moor 12.7C maximum, Aboyne 9.0C minimum, Cranwell 37.6 mm, Guernsey Airport 6.7 h.)

On the 31st there were a few brighter, warmer spots, but many places were cloudy and rather cool. Some light drizzly rain drifted S from E Scotland into N England, whilst the Se area of half of England became showery; some of the showers were heavy, and they became increasingly slow-moving, so giving some localities large rainfall totals to end an already very wet month. There was thunder in parts of SE England. (Cavendish 23.1C, Ballypatrick Forest 13.1C maximum, Wick Airport 9.0C minimum, High Mowthorpe 12.2 mm, Guernsey Airport 9.9 h.)
