Met Office is warning of extreme heat as London has been given a red weather warning, the highest level of warning.

In place on Monday 18 and Tuesday, 19 July temperatures are set to rise to 37.C in the region, marking record-breaking numbers. 

With the office warning that there will be an exceptional hot spell which will pose a “population-wide danger to life”.

A Met Office spokesperson has said: "Exceptional, perhaps record-breaking, temperatures are likely on Monday, then again on Tuesday.

"Nights are also likely to be exceptionally warm for the UK, especially in urban areas.

"This is likely to lead to widespread impacts on people and infrastructure.

"Temperatures are expected to drop away from Wednesday onwards."

What to expect from Met Office extreme heat weather warning:

  • Population-wide adverse health effects experienced, not limited to those most vulnerable to extreme heat, leading to serious illness or danger to life
  • Government advice is that 999 services should be used in emergencies only; seek advice from 111 if you need non-emergency health advice
  • Substantial changes in working practices and daily routines will be required
  • High risk of failure of heat-sensitive systems and equipment, potentially leading to localised loss of power and other essential services, such as water or mobile phone services
  • Significantly more people visiting coastal areas, lakes and rivers, leading to an increased risk of water safety incidents
  • Delays on roads and road closures, along with delays and cancellations to rail and air travel, with significant welfare issues for those who experience even moderate delays
