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.

9 days so far this month have had maximums greater than 20C but many
more have come very close.

Sunshine levels have been quite good for the last couple of weeks and
the total now stands at 168.7 hours. That's more than for August and
this month should pass July's total too.

Even with the sunshine, it has been a totally different month to
September last year when every day had a maximum greater than 20C and
the monthly mean temperature ended up at 16.7C.

This September has continued the summer trend with a dominance of cool
or cold nights but generally average day temperatures though with a
complete absence of any really warm of hot days.

It has been a strange summer.
