As temperatures move into the low 30sC for England, the heatwave continues. Tuesday 1st July might be even hotter but with changes from the northwest. Be gentle with people if they look tired.
As more of the UK faces a very warm, often hot Monday, England continues with heatwave conditions. The top temperatures at the weekend were 31.3C at London Heathrow on Saturday and 31.0C on Sunday for St James’s Park. Hull and nearby Leconfield have seen five days of heatwave, surpassing the threshold conditions for the East Riding of Yorkshire. It will be hot again on Monday. Cambridge, Heathrow, and the Birmingham areas are just a selection of places in England that have experienced three days of heat and met the official requirements for a heatwave.

Monday looks to be the hottest day of the year so far with a forecast maximum of 34C. This will be the hottest opening day of the Wimbledon tournament, although it is starting a week later than usual. And at this time of year, it matters. The June UK record is 35.6C from 1976. The July record is 40.3C the all-time UK record from 2022 in Lincolnshire. Tuesday could go higher, but with a change from the northwest.
Advice for keeping cool in this hot weather
Keep the curtains and blinds closed in rooms that face the sun, bearing in mind how that will change during the day if you are out. There is a light southerly breeze today, so consider if you can make a through breeze work, or if opening windows will just let more heat in.
This is not an ordinary summer’s day. It is very unusual to experience temperatures this high in June. People with existing medical conditions, who are elderly or young children, may need a slower pace. Remember to take care of pets too, dogs can overheat.
Do drink more water, seek shade or cover up if you are out and about. The hottest time of the day is between 11am and 3pm, but into the late afternoon can still feel oppressive in the sunshine. People on medication are being advised to keep that cool, to make sure that it remains effective and be aware that heat is an extra layer of stress on the body.
Adjust your plans and certainly exercise times. Find out what to do if someone shows symptoms of heat exhaustion and heatstroke. Look at clothing labels and choose natural fibres. Cotton is much cooler to wear than sweaty polyester. There has been a suggestion to put pyjamas in the freezer, but that seems quite a personal choice. If you do have the option to sleep downstairs, that might be a bit cooler. If you are hot and bothered when you get home from work, washing your hands in cold water can be an instant help.
The outlook
It is possible that Monday night will be a Tropical Night in places where temperatures do not fall below 20C. Keeping rooms cool by day will help a bit by night and you can further reduce the heat generated in a home by turning off electrical equipment that is not in use.
Northeast England down to the Humber will feel less hot by Tuesday afternoon as fresher air from the Atlantic reaches over more of Britain from the Northwest. Southeastern Britain faces another hot day but this time in the month of July. The temperatures might go a touch higher on Tuesday as the breeze will be from the west or northwest, lighter than on Monday and from heated land rather than the waters of the English Channel. 35C is possible.
Scotland and Northern Ireland start their school summer holiday with very warm air but rain in the far north and west. This cold front will be moving southeast but will take its time and waver about on Tuesday over the far north of England, southern Scotland with some heavy downpours. The worst of the heat and humidity will finally clear away from Kent on Wednesday morning, which means another sticky, close night for London and the Home Counties on Tuesday night.
However, the week does stay very warm for much of England, but not as muggy and humid.
