The\u00a0red warning joins the existing Amber Extreme Heat Warnings<\/a>, which\u00a0stretch from\u00a0Monday\u00a0through\u00a0to\u00a0the end of\u00a0Thursday, covering much of\u00a0southern and\u00a0central\u00a0England as well as\u00a0much of\u00a0Wales.\u00a0<\/p>\n

Temperatures will quickly rise on Monday\u00a0and are forecast to reach\u00a034\u00b0C\u00a0in southern parts of England.\u00a0However, this brings with it the chance of\u00a0thundery\u00a0showers\u00a0for some.\u00a0\u00a0<\/p>\n

The heat will build further into Tuesday, with highs of\u00a037\u00b0C forecast for southern England and\u00a035\u00b0C\u00a0in\u00a0southeast Wales.\u00a0The peak of the heatwave is now forecast for Wednesday and Thursday, when temperatures are expected to climb to\u00a0at\u00a0least\u00a039\u00b0C\u00a0and\u00a0there\u00a0remains\u00a0a\u00a0chance of this\u00a0being exceeded in places.\u00a0<\/p>\n

By Friday conditions will be less hot, with highs of 32\u00b0C forecast\u00a0across eastern areas.\u00a0\u00a0<\/p>\n

Overnight temperatures will also be\u00a0very high, with widespread Tropical Nights, where the temperature does not drop below 20\u00b0C,\u00a0across\u00a0parts\u00a0of\u00a0England\u00a0and\u00a0Wales,\u00a0especially in urban areas.\u00a0Humidity is also a factor, making this heatwave even more\u00a0impactful with heat stress a\u00a0danger to all.\u00a0\u00a0<\/p>\n

Dew points, which\u00a0indicate\u00a0how humid the air is, are forecast to\u00a0reach\u00a0around\u00a022\u00b0C\u00a0in places\u00a0on Wednesday and Thursday. For comparison, during the\u00a0record breaking\u00a0July 2022 heatwave they were\u00a0widely lower, highlighting\u00a0how oppressive this heatwave will be.\u00a0\u00a0<\/p>\n

It is now\u00a0expected\u00a0that\u00a0the\u00a0current\u00a0UK\u00a0highest temperature on record for June\u00a0will\u00a0very likely\u00a0be\u00a0broken, this being\u00a035.6\u00b0C\u00a0recorded in Southampton in June 1976\u00a0and Camden\u00a0Square in\u00a0June\u00a01957.\u00a0In addition, the Wales\u00a0June temperature record of\u00a033.7\u00b0C\u00a0set\u00a0in\u00a02000\u00a0is\u00a0also\u00a0likely to be broken.\u00a0The June record\u00a0for\u00a0Scotland\u00a0stands at\u00a032.2\u00b0C\u00a0and\u00a0for\u00a0Northern Ireland\u00a0it\u2019s\u00a030.8\u00b0C, and\u00a0while these\u00a0are less\u00a0likely to\u00a0be\u00a0broken,\u00a0even\u00a0here we\u00a0are\u00a0expecting\u00a0daytime\u00a0temperatures\u00a0in\u00a0the\u00a0high\u00a020\u2019s\u00a0perhaps\u00a0low\u00a030\u2019s\u00a0\u00b0C.\u00a0<\/p>\n

Met Office Deputy Chief Forecaster\u00a0Mark Sidaway,\u00a0said: \u201cRed warnings\u00a0<\/a>are\u00a0reserved for\u00a0the most\u00a0severe\u00a0events\u00a0and\u00a0we\u2019re\u00a0expecting\u00a0severe\u00a0and\u00a0significant impacts\u00a0from this\u00a0heatwave,\u00a0with\u00a0health\u00a0impacts\u00a0likely for\u00a0many,\u00a0even\u00a0beyond those who are\u00a0normally\u00a0more vulnerable to\u00a0the heat.\u00a0The\u00a0last time the UK\u00a0recorded temperatures this high\u00a0was\u00a0in July\u00a02022,\u00a0but on\u00a0this\u00a0occasion\u00a0the heat\u00a0is\u00a0expected to be\u00a0accompanied by\u00a0high\u00a0humidity.\u00a0\u00a0<\/p>\n

\u201cAs well as\u00a0very high\u00a0daytime temperatures, there will be consecutive nights where temperatures do not drop below 20\u00b0C, which is called a Tropical Night. This will make it\u00a0very hard\u00a0for people to recover from the daytime heat,\u00a0exacerbating\u00a0the heat stress impacts.\u201d\u00a0<\/p>\n

The forecast heatwave\u00a0brings with it\u00a0the\u00a0likelihood of\u00a0record-breaking\u00a0June temperatures and\u00a0very high\u00a0humidity. The combination of heat and humidity will be oppressive and\u00a0bring impacts across society\u00a0from public health and infrastructure,\u00a0to power and water supplies.\u00a0\u00a0<\/p>\n

The warning also\u00a0highlights\u00a0the\u00a0potential\u00a0of\u00a0heat-related issues for\u00a0a range of sectors such as transport,\u00a0energy\u00a0and water supply.\u00a0\u00a0<\/p>\n

An increase in potential water safety incidents is also noted, as more people are likely to visit coastal areas,\u00a0lakes\u00a0or rivers.\u00a0\u00a0<\/p>\n

The UK Health Security Agency has also issued a series of\u00a0Heat Health Alerts<\/a>, which specifically highlight the potential health and social care impacts.\u00a0\u00a0<\/p>\n

The exception for the hot conditions is further to the northwest,\u00a0which is\u00a0seeing\u00a0more frequent cloud and rain on\u00a0Monday\u00a0with near-average\u00a0temperatures.\u00a0Cloud lingers for much of the\u00a0week in the far northwest, with\u00a0more persistent\u00a0rain possible at times\u00a0later in the week.\u00a0\u00a0<\/p>\n

Staying safe in\u202fcold water\u202f\u00a0<\/p>\n

People heading to the coast should be mindful that sea-surface temperatures are not as high as they would be in mid-summer.\u00a0<\/p>\n

Samantha Hughes is the National Water Safety Partner at the RNLI. She said: \u201cWith warmer weather approaching,\u00a0it\u2019s\u00a0important to remember that the water is still cold. Entering it unexpectedly can lead to\u00a0cold water\u00a0shock, causing a sudden increase in breathing and heart rate, which may trigger panic.\u00a0<\/p>\n

\u201cIf you find yourself struggling in the water, remember to Float to Live: tilt your head back so your ears are submerged, relax and control your breathing. You may need to gently use your hands to help you stay afloat, and\u00a0it\u2019s\u00a0ok if your legs sink\u2014everyone floats differently.\u00a0<\/p>\n

\u201cWhere possible, always choose a lifeguarded beach, and swim between the red and yellow flags. In a coastal emergency remember to call 999 for the coastguard.\u201d\u00a0<\/p>\n

You can find\u202fwater safety advice<\/a>\u202fon our website and in the refreshed\u202fMet Office app<\/a>, now featuring a dedicated beach forecast with tide times, wave\u202fheights\u202fand sea-surface temperatures, as well as guidance on UV and pollen levels.\u202f\u00a0<\/p>\n

If\u202fyou’re\u202fplanning\u202fon enjoying\u202fthe water, here are three simple ways you can help keep yourself safer:\u202f\u00a0<\/p>\n

Check the water temperature, our seas and river temperatures are low enough to cause\u202fcold water\u202fshock when 15\u00b0C or lower\u202f\u00a0
\nWear a wetsuit if you plan\u202fon spending\u202fany length of time in the water\u202f\u00a0
\nWearing a life jacket or swimming buoy can increase your chances if you experience\u202fcold water\u202fshock\u202f\u00a0<\/p>\n

Hot weather and climate change\u00a0<\/p>\n

The current highest temperature on record for June is 35.6\u00b0C and there\u00a0remains\u00a0a chance of this figure being challenged next week.\u00a0\u00a0<\/p>\n

The frequency and intensity of heatwaves\u00a0has\u00a0increased worldwide. Met Office projections\u00a0indicate\u00a0that hot spells will become more frequent in our future climate, particularly over the south-east of the UK. Temperatures are projected to rise in all seasons, but the heat would be most intense in summer.\u00a0<\/p>\n

It is\u00a0virtually certain\u00a0that human influence has increased the occurrence and intensity of extreme heat events. Numerous climate attribution studies have shown that human influence increased the chance that specific extreme heat events would occur, such as the summer of 2018 and July 2022.\u00a0<\/p>\n

When will the heat ease?\u00a0\u00a0<\/p>\n

Temperatures will peak on Wednesday and Thursday, though there remains a chance of this being exceeded in some spots.\u00a0\u00a0<\/p>\n

High pressure is forecast to gradually move to the east on Friday and through the weekend, which will ease temperatures slightly, though those in the southeast will retain the exceptional warmth the longest.\u00a0\u00a0<\/p>\n

Friday is likely to see at least some rain and cloud arrive from the west for a time, particularly in the northwest, and the weekend will see a gradual transition to a more westerly influence with temperatures dropping towards the high 20s Celsius on Saturday and drop further on Sunday and into the start of next week.\u00a0\u00a0<\/p>\n
