September started with some fine sunny days

It was another month of below average sunshine hours, I suspect worse than August and after such a good start to the month. In August around 30% of actual daylight hours were sunny set against only 26% for September. Don’t hold me to these figures it’s a difficult subject to measure with any degree of accuracy!


Rainfall has been only slightly above the typical average for September. We had 10 days in the month with some rainfall with most of the rainfall early in the month. With the cooler temperature there has been no need to water the plot. Our brassicas planted in late August have grown well.

We also had some very windy weather this month. I recorded 5 days with wind gusts of 15mph or more even in our sheltered garden protected by house and trees. The maximum wind gust speed recorded was 23.0mph on the 24th of the month, which is a yearly high. Fortunately this only resulted in minor damaged on the plot.

The cardoons suffered in the windy weather

On the plot it’s the time of year when clearing the remaining summer crops is the main priority. It’s time to take stock of what grew well and what didn’t and consider how things might be improved upon for next season.

Carrots have done particularly well this year

September 2010 Weather Summary

September started off really well with some super sunny days and raised hopes were high for a really good September to make up for the poor July and August. Alas this was not to be as the month gradually deteriorated and by the end of the month we were struggling to find any sunny days at all.
