The Met Office has told MyLondon why Heathrow is often the hottest part of the capital. Amid an amber heat health warning from the government, the mercury could get as high as 34C at Heathrow today (Tuesday, August 12).
People in the know may have come across the term ‘Urban Heating’. For those who haven’t, it’s the idea that cities are hotter than more rural areas as they have more concrete and tarmac, materials that absorb heat.
But because Heathrow has such a huge airport with great amounts of heat-absorbing materials concentrated in one place, the area constantly scores higher on thermostats than neighbouring zones.
Amber warnings are in place for the East Midlands, West Midlands, east of England, London and the South East until Wednesday, with yellow warnings in place for the remainder of the country.
The UKHSA has warned of significant impacts across health and social care services due to the high temperatures, including the potential for a rise in deaths, particularly among those aged 65 and over or with health conditions.
People are recommended to keep their homes cool, wear appropriate outdoor clothing and keep out of the sun during the midday heat, and know the signs of heat exhaustion and heatstroke.
Dr Paul Coleman, a consultant in public health at UKHSA, said: “Temperatures are forecast to rise above 30C across central and southern parts of the country over the next few days, and generally hot weather is expected across most regions of England.
“These kind of temperatures can result in serious health outcomes across the population – particularly in those who are vulnerable, such as the elderly or those with serious health conditions – so it is important that everyone takes sensible precautions while enjoying the sun.”
