The last couple of days have made me think on several occasions that
there must be something wrong with the anemometer as it has for long
periods registered 0 mph. I would go outside and check to see if the
cups are whizzing round but no, totally stationary.

From 23:45 on the 6th to 09:00 on the 7th the anemometer registered no
wind. And again today from 22:15 on the 7th to 11:00 there was no
measurable wind.

Normally there is a land breeze at night that blows at 2 to 5 mph all
night until it stalls just after dawn and the sea breeze kicks in from
mid-morning.

More the remarkable today was that the sun was shining all morning yet
no wind was registered until 11:00.

Total wind run for today was just 21 miles and maximum gust was 9 mph.
Given my near coastal location and it is summer, and the was sun
shining, this is very 'windless'.
