Thunder

No thunder was heard in Shoreham in November.

Wind

Southwesterly winds only occurred on 16% of the days during November, with double that total blowing from the northwest. In a very cyclonic month (the average pressure was only just above 1000 mb) it was not surprising that there was also a fair representation of winds from both southeast and northeast. The 2nd was a particularly windy day, and at Shoreham Airport southwesterly gusts of 38 knots (43 mph) late on the evening of the 1st, steadily increased during the night and peaked late in the morning of the 2nd at 57 knots (65 mph), but with gusts not falling below 30 knots (34 mph) until late in the evening. Unusually for an autumn month, no further gusts above 30 knots (34 mph) were recorded during the remainder of the month.    

Fog

There was no fog observed in this part of Shoreham during November, although it was very misty at times on the 1st.
