Yesterday saw huge differences in weather over very short distances.

During the morning an intense shower formed over the Penwith peninsula, developing over the land as soon as the air hit the south coast.

This remained almost stationary from 11:00-13:00. During this period 25mm of rain fell over the moors (20mm at Trengwainton, just behind Penzance.)

At my station, 600m or so from the sea front, the stream in my garden steadily rose before any rain fell. Eventually I had a sharp 20 min burst which gave approx 7mm, the edge of the rain being near the harbour.


Lovely sunny start this morning after a clear, still, cold night. Min 7.8C
Not a cloud in sight over the sea http://www.landsendweather.info/

Unbroken sunshine this morning helped push the temperature up to 16.8C, the highest since 21st.

Sun just clipped the land based Cu from 13:00-14:30, though the clouds's receding and diminishing now. The temperature which dipped back to around 15C under the cloud is on the rise again.
