The Government is advising Londoners where they can keep cool in the capital during the 34C (95F) heatwave.
With temperatures set to spike next Monday (30 Jun), officials have created a map to help commuters cool off.
They could be deemed as being nanny state-like measures, as most Brits know how to stay safe in the sun.

From free water fountains to the shade of trees, the map is littered with areas to battle against the heat.
The guidance is split into five categories, including drinking water fountains, tier one and two cool spaces, tree canopy cover and cooler spaces.
Trekking from Tube to Tube can be thirsty work; littered across the capital are places for Londoners to fill up their bottles.

Fountains such as the one in the plaza, Lower Marsh, Waterloo, are ideal for a refreshing drink.
Tier one spots are filled with key amenities and are open to the public for the majority of the week.
The iconic Southwark Cathedral, Southwark, central London, is equipped with lower temperatures, free seating and toilets.
The Mayfair Library falls under the tier two category due to being open less frequently.

Luckily, there are plenty of green spaces available in the capital, such as Hyde Park.
The area provides excellent shade for members of the public in the form of tree canopy cover.
The Government map also features a heatmap of the coolest areas, as reported by Need To Know.
Bodies of water such as the River Thames are listed in this section, making the river banks a great spot to cool off.

The map was published by the Mayor of London City Intelligence, combining data from the London Tree Canopy Cover, the GLA Drinking Fountains Map and OS Data.
A spokesperson for the Government stated: “Cool Spaces are venues and outdoor spaces open to all where Londoners can take respite on hot days.
“Cool Spaces have been put forward by boroughs, community groups, faith-based and other organisations following an invitation to register by the GLA.
“The tiered approach to classifying Cool Spaces is meant to provide Londoners with an understanding of what they can expect from venues and how some Cool Spaces can better suit their needs.
“Parks and outdoor spaces that provide shade, shaded seating, drinking water and toilets are signposted on the map, but may still be very hot during hot weather.
“The tree canopy layer intends to provide indicative complementary information on potential shade in public open areas across London.”
Nanny state refers to a government that is perceived as excessively protective or controlling of its citizens.
