Well, sunshine figures look like being well up to normal, rainfall a little below, but like August a complete lack of any really warm weather.
Last September saw 18 days when the temperature reached 20C, this month just 1! The average temperature is 2C lower than last September, nearly 3C lower than September 2006.
Even the forthcoming spell doesn't look that warm, high teens at best for most people, with a distinctly cool feeling easterly along some North Sea & more east facing Channel coasts. Luckily Cornwall also has a sheltered north coast.
Still, it's sunny now, might get an 18C today (17.1C yesterday).
Yesterday's heavy ground sea
