Notes from a heatwave

3 days over 30C does not constitute a heatwave - it’s called ‘Summer’.

It is not necessary to remind people that London is hotter than Rio, Rome, the Canaries and the Bahamas. It won’t be for long.

Carry water with you everywhere. Even on a ten-minute tube trip and sip from it at 60-second intervals, thousands of people die of dehydration every year in Britain you know.

Moan about the heat – that will bring back grey skies and drizzle. Then moan about that.

It is not necessary to run in tracksuit pants and a long sleeved top when the temperature is over 30C.
