No Rain and No wind comes to an end

There’s not been much to say about the weather through August and September. All that has changed as we come to the end of September. For the last couple of months there’s been no unusually hot days or cold days to report as well as no windy weather or wet days.

 The allotment has become very dry with no rain to speak of since the end of July. Our cardoons have certainly suffered in the dry conditions.

Cardoons - September 2021

Our overwintering garlic and onions have needed watering regularly since they were planted a few weeks ago. The same is true of our sweet Williams for cut flowers next spring and our new strawberry plants which we hope will produce some strawberries for next summer.

However, the most obvious weather effect over the last few months has been the lack of low pressure systems that bring wet and windy weather.

The table above shows the average wind speed for each month beginning in 2011. I’ve boxed out in red the last six months for which the average wind speeds for each month have all been below average.

There is no guarantee about anything when it comes to weather.

A mini September heatwave

September has started off warmer than August. However, the heatwave to start the month was short-lived like most of the hot weather this year. It gave us our hottest weather since the middle of July.

Temperature Records January - September 2021

On the 7th September, the temperature reached 29.4°C (84.9°F) equalling our 12 year September record high temperature. The previous occasion was on 13 September 2016. The spell of warm weather means that by the 13th of the month the average temperature of 17.2°C (63.0°F) is the highest I've recorded in the last 12 years. The previous highest was 17.1°C (62.8°F) in 2016

On Thursday we took Ruby for her regular walk around Nostell Priory.

There are now the first few signs that autumn is here. The summer flower meadows have been cut and baled ready for use through winter.

As we walked around the lake some of the trees are just beginning to show their autumn colours.

The forecast was for the hot weather to break down with heavy rain and thunderstorms. As usual for us, the rain and thunderstorms didn't materialise. Our last decent rainfall was at the end of July. The allotment is now very dry and any autumn digging is on hold until we get some rain. The forecast is for some rain on Tuesday afternoon but will it be correct.

Meteorological autumn is here - what happened to summer?

Meteorological autumn has arrived but quite frankly it seems to have been here for a few weeks now. 

August was, without doubt, the poorest of the summer months finishing in eighth place out of the last 12 years. It also finished up as the driest over the same period.

August Temperature & Rainfall 2010-2021

I was surprised, last week when the UK Met Office said that we’d had a good summer well up the table of warmest summers. I’d have said that we’d had a pretty poor summer so I was surprised to find that, based on average temperatures from my weather station, this summer ranks third out of the last 12 summers. Perhaps average temperature isn’t always the best way of telling whether we’ve had a good summer or not.


August would have had a lower average temperature if it hadn’t been for a run of above average nighttime temperatures. Generally, daytime temperatures were around average or below and we didn’t have any “hot “ days at all, with the month’s highest temperature only managing 24.3°C degrees.

Allotment wise, with fruit and vegetables, as usual it has been a bit of a hit and miss season. Most of our tree fruit suffered badly from the cold weather in April and May with late season frosts damaging the apple, pear and plum crops. However, we've had one of our best potato crops for a good number of years. 

Casablanca Potatoes - 02 July 2021

Our early pot-grown potatoes were a disaster this year but all the ones grown on the allotment produced excellent crops. This year for some reason our potatoes avoided any wireworm damage and had very minimal damage from slugs. After a poor year last year, with one bed of onions failing completely, this year's crop has been excellent with lots of good-sized onions.

Onions - Hercules, Centurian & Sturon

We also had an excellent crop of garlic for the first time in many years. Our first sowing of peas failed completely, once again probably due to the cold weather in April and May but later sowings have been much more successful. 

Now we are into autumn we would normally be thinking about harvesting our apples and pears but we've very few of either to harvest this year.

It's certainly time to start getting beds cleared of their summer crops so that they can be dug over before any really bad weather sets in. The more clearing and preparing we can do through autumn and early winter the better prepared we will be for the start of the next growing season.
