Two weeks ago, I was able to wander around in a tshirt, but - once September crept in, evenings did require a light weight woollen pullover.
Last week saw the appearance of mid-weight woollen sweaters, and today, - with brutal showers - I decided to forego my (aged, but still excellent) trench coat raincoat, and retrieve my Barbour coat, a garment that has not been needed since around Easter, a superb jacket that I have had for well over a decade, invaluable in wet autumnal weather.
Unfortunately, once my Barbour jacket is retrieved, it tends to be worn regularly for the better part of the following six months........
September doesn't bring the end of summer where I live. Instead, it's often the month when temperatures are the highest. Summer will continue thru to the end of October
