Warm and dry on Saturday then foggy morning

The pleasant sunshine of 4.7 hours on Saturday, principally in the morning pushed the temperature to a peak of 21.7C, exactly as on Friday and 3C anew average.

A very chilly night followed under clearing skies that saw the thermometer drop to 8.1C at 07.40. This was the coolest night since 27th August and 1C below average.

The drop in temperature allowed radiation fog to form in the early hours that at dawn was variable, mainly in the River Og valley, later River Kennet valley, when tops of trees could be seen poking through the low lying radiation fog.

By 07.30 the sun had risen above the low lying fog and begun to evaporate the condensation.
