Norfolk will be hotter than Santorini this weekend, according to Met Office forecasts.
The forecaster has said conditions will become increasingly dry and sunny over the next few days.
A spokesman for the Met Office said: "A slight change in wind direction towards the end of the week will allow temperatures to climb across Norfolk, reaching the low to mid-twenties by Saturday."
He added that temperatures could reach 25C on Sunday, making it warmer than Santorini in Greece where it is predicted to be 24C.
