The cloud finally cleared last night from Farnborough and it remained mostly clear through today.
As a result, we had a diurnal temperature range of 17.6C, from a minimum of 0.3C at 0630 (with ground frost) to a maximum of 17.9C at 1430.
Not that unusual for this time of year, but still impressive. The maximum temperature was the highest since October 31st.

Sunny at dawn, then thick fog off the sea from around 0700 to 0900 UTC reduced visibility to 300m. Fog then lifted to leave a sunny dry and cool day.


It felt mild, even warm in the sun, but I only recorded a screen maximum of 9.1c.

Tmin was 3.8c.

Grass minimum dropped to 0.0c.

Trace amounts in the gauge due to dewfall.

It seems to depend very much on the location at the moment, with sea temperature being still cold.

I had a min of 1.4C and a max of 19.4C today, so an even wider diurnal range of 18.0C.

Sea is definitely still chilly at around 9 or 10C.
That means we have only had maxes of 15C in the last two days, and that is when the sea breeze weakens in late afternoon.
Beautifully sunny though.

Diurnal range has been about 10CdegC.

On Monday the minimum temperature was a rather chilly 0.2°C but the day soon warmed and without a sea breeze that day, the temperature topped out at 21.0°C.

So an unusually large (for here) diurnal range of 20.8°C.

Sea breezes yesterday and today meant the maximum temperatures were no where near as high.
