The current forecast for Penzance is excellent. It is mostly moderate, occasionally good in shelter, simply because there is so much sea spray in the air.

I know sea spray isn't taken into account, but it's a pretty easy parameter to forecast. Obviously too much effort for the MetO who prefer visibility forecasts to be wrong in Atlantic locations most of the winter. I've been told there are no plans to introduce sea spray as a factor, I mean why bother wth Nowheresville. Why bother with mist then?
Yesterday saw a maximum of 15.3C, meaning every day this month has exceeded 15C. Previously, the maximum number of days exceeding 15C in November was 7 in 2011.
