GRAVESEND has the highest recorded temperature so far this year.

Temperatures soared up to 30.9 degrees on June 27 and are expected to be even more sweltering this weekend.

This triggers concern over health and people are being advised to be extra cautious in the sun.

Head of Health Forecasting at the Met Office, Wayne Elliott, said: “While there is the possibility of daytime temperatures reaching trigger thresholds, it is the night time values which are of real concern.

High humidity and the lack of any breeze could make matters worse for people with underlying health problems."
