People have flocked to parks and open spaces to enjoy long, sunny days and temperatures of up to 30 degrees.
The heatwave is expected to continue until the middle of the week when thunderstorms are predicted for many of us.
Our photographer Brian Eyre caught up with some of the residents making the most of the sunshine.
