Yellow heat warnings have been issued across much of England and forecasts suggest temperatures could rise to as high as 32°C (90°F) on Tuesday.

Warnings from the UK Health Security Agency (UKHSA) apply to all areas of England, except the north-east and north-west, until Wednesday.

The agency said the hot weather could have a “significant impact” on the health and social care sector, particularly in the south-east of England and London.

The Met Office has also issued a yellow warning for thunderstorms for the rest of the week, covering most of England and parts of Wales.

The UK Department of Health (UKHSA) warned that the heatwave could potentially lead to an “observed increase in mortality across the population, particularly in the over-65s age group and those with underlying health conditions. But effects could also be seen in younger age groups.”

According to the Met Office, temperatures in London and southeast England could reach as high as 32 degrees Celsius on Tuesday.

In many parts of the country, temperatures will be four to five degrees warmer than usual for this time of year in July, the meteorologist said.

Only the far northwest of Scotland and parts of Northern Ireland will see some cloud and possibly rain on Monday and Tuesday.

The hottest day of the year so far was July 19, when a temperature of 31.9 °C was recorded in St. James’s Park in central London.

Is this a heat wave?

It is possible that some places in England will reach the criteria for a heatwave, when temperatures exceed the temperature limit set by the Met Office for three consecutive days. This varies depending on your location in the UK.

In Greater London, this limit is 28 °C. In Scotland, Northern Ireland, Wales and most parts of northern and western England, it is 25 °C.

If temperatures do not reach 25 degrees anywhere in Scotland on Tuesday, it will be the first July since 2010 in which temperatures there do not reach this level.

The drier weather across much of the country is expected to change on Thursday, when the Met Office issued a yellow warning for heavy rain and thunderstorms.

The warning applies to most of southern England, the Midlands, parts of Wales and large parts of northern England. It warns of “lightning, hail and gusty winds” that could cause disruption.

It will come into effect on Thursday at 00:00 and end at 23:59.

For the rest of the month, windy weather is expected in the northwest, while drier and brighter weather will prevail in the southeast.

A quieter phase is expected around mid-August.
