September 2017 was a lack lustre month compared to some recent Septembers which turned out to be an extension of Summer. This Year the weather was very much an early Autumn month with spells of rain and breeze forming a lot of the character of the month. No surprise that rainfall was above average again with a total of 123mm for the month being a wetter month than August. The 16th was a partciularly wet day with 18mm falling in the 24 hour period. It wasn’t raining all the time though with 7 days with no rain recorded at all but dry spells were hard to sustain for any length of time with the longest period of dry weather lasting just 3 days right at the turn of August into September.
Temperatures were suppressed to below average levels for September with 13.4C being a full 1C lower than the long term average of 14.4C. Having said that Septembers in 2015 and 2012 were cooler so nothing exceptionally cool recorded. We did achieve a couple of grass frosts through the month but you would have had to of been up early to see them with the morning of the 22nd seeing the coldest monthly temperature of 2.6C.
It wasn’t a windy month with a valley wind gust of 25mph being the highest recorded while over the hills above us 40mph was achieved on the 12th. The predominant direction of the wind through September was between SW and NW with over 70% of the time seeing winds from that source indicative of the Atlantic based weather of the month.
Sunshine was below average due once more to the Atlantic influence of September’s weather with a total of 93hrs falling a good 25hours short of the long term average. The sunniest day was the 1st with 11hrs of sunshine then aided by the longer daylight hours available at the beginning of the month. There were 3 days with no sunshine at all, namely the 3rd, 25th and the 29th.
There was no exceptional weather to report on through September with no thunder, lightning or hail reported so no disruption to travel or properties from high winds.
By the time you are reading this we will of moved into deep Autumn with all it’s glorious colours at their best at the end of October. The problem is the darkness has really taken hold of our lives now for 3-4 months especially given the clocks have moved back 1 hour recently. So its a case of batten down the hatches for the next 3-4 months when no doubt I will be reporting here on events of the Winter in terms of snowfall, rainfall, frosts, fogs and ice.
