Winter 2014-15 wasn't bad around here. A couple of cold spells and all three winter months had snow. It was certainly a million times better than the one before it for wintry weather.

I recognise your area may have missed out though.

 

We've had snow most winters, but mostly fleeting (I think it was Boxing Day evening 2014 that had the unexpected dumping... unfortunately all gone by the morning)

My yardstick, though, is coloured by the amazing spells we had in 2009/10 (2 of them!), 2010/11, 2012/13

Another stinking humid day, on a par with what used to be the worst you could expect during a summer. The very air reeks of humidity.

The average dewpoint this month so far is a whopping 15.0C, having varied from 9.8C to 20.1C (!) over the course of the past 19 days. That's horribly high and far beyond anything I've recorded going back over the last decade's worth of Septembers.

The GFS has performed abysmally during this month, too, consistently undercooking the dewpoint by 4 or more degrees. I don't know why, and no, it's not just my station being weird - all the others in the local area are showing similar stats.

I'll be most relieved when this humid dry season (no rain for 4 weeks!) is over. A return to seasonal conditions would be more than welcome here!

Without a doubt the most humid extended summer season that I can ever recall. DP's have become somewhat more tolerable over here over the last few days, but still running way above average and barely any more pleasant, due in no small part to the constant lack of any sufficient breezes. Proper cool early autumn nights, that would help in no small part in cooling the house down, do not seem to exist this year either.

I agree completely with that, I look forward to some cooler, fresher weather now as the humidity and warm nights have dragged on far too long now. Last night was still like 16c at 10pm which when you've been in inside a bar that is way too hot, it's frustrating when you go outside to still warm and very humid air. The models have been indicating a switch to cooler fresher air for a while now but it seems to keep getting pushed back, let's hope it finally arrives soon.

16C @ 10pm is actually quite fresh, or refreshing.. but then again I'm a southerne lol

Yeah it was around 16/17c plus very high humidity, certainly not fresh to me!

At this temperature the humidity isn't really noticeable unless it's low. 

16C with 100% would mean a dew point of 16C, and in all likelihood it would be misty damp type weather. 

Outside now here we have a dew point around 14C with an air temp of 17.5C and despite the calm wind it does feel chilly.

It was like 17c air temperature and 14c dewpoint. Not terribly warm I agree but for 10pm at night I would hope for it to be a bit fresher than that at this time of year, and when you've been indoors where it's been warm it doesn't cool you down enough.

Now it's 13c with a 10c DP which feels quite nice for walking around in but I still like it a little cooler than that at night.

We were sat out with friends till about 11pm last night, after a BBQ

It was great!

Fresher today (miserable rain earlier ) and was a little chilly on a big walk with the dog late afternoon. Needed our hoodies!

Not relishing an unsettled end to September.

Yes, totally agree. Any sign of coolness in the models always seems to be pushed back just a little further with nearly every run. And sure enough, looking just at my own location. Early forecast lows of 6 or 7c (around average) for the end of this week are now replaced by the usual 12c to 14c, which are way higher than the July average.

I am happy with warm nights so the heating stay off, as you aware they increase the bills next month so really want to reduce the heating as so far this month so far had been heating free since late May.  Long this warm nights and average day temps continue as fars as to late October so heating is less often.  Last year was the longest streak of heating on from late Sept to late May.  Need this year from October to March with few in April before turning off for good.

All those moaning about the warm,muggy nights,you need to remember the climate has changed and think of September as a now a summer month. Looking back through the CET autumn is the season that has warmed/changed the most over the past 35/40  years especially October. We have not had a proper cold autumn since 1993. I certainly remember the leaves turning on the trees around this time in september,now they are still fully green in there summer coat until well into October.

Yes and also autumn is generally a muggy/humid season anyhow so I shouldn't moan too much. Though last September we did have some cold nights and even some frosts at the end of the month so it's no guarantee that it has to be warm and muggy nowadays, but the stretch of warm nights has been longer than normal this year.

Yes not had a properly cold Autumn for a very long time although perhaps 2010 was on the cold side? We have had some cold winters/springs since then but not really a proper cold Autumn, would make a nice change to have one.

September has always always been a transitional month from summer to early autumn. It's not normally known for cold & frosty night's away from sheltered  valley's in places like Scotland's & Wales. 

The long term average September overnight low for my location is 12.8C - starting the month around 14/15 ending around 10/11. The average day time is still close to 21C.

That's interesting as it puts you warmer than London. My closest station with a long term Met Office average is Greenwich Park, which averages 20C max in Sept and 11.4C min (those are 1981-2010 averages). I'm surprised Portsmouth is that much warmer to be honest.

Typo on my behalf 🤣 it's close to 20C not 21C 😅 However the night temperature was accurate.

I'm not seeing much 'transition' with this and recent September/s tbh. October has become the new September in this regard I think, and Novembers have become the new Octobers.

When we have warm, sunny weather in May, it's generally applauded. Similar conditions in September and a number of people complain.

With this September, you are really spoiling us!

Even some average late September conditions are going to come as something of a shock. Taking the extended May-September summer period I see this month as being 'payback' for the shocking May we endured.

Just an anecdotal observation, as a Rainbow, Brownie & Guide Leader for 10+ years (stopped in 2019 due to illness, though it’s glorious having my evenings and weekends back!), we did many events for the girls in September, and with the exception of a couple of events (fortunately indoors) where we’ve had torrential rain, it’s always been fine weather.

I’ve also done umpteen camps in September & again, from dawn til dusk it’s usually been in the mid teens to early twenties (I think we had frost once in the morning of a later September camp at the end of the month), but that’s an anomaly in my experience.

In fact, we’ve had more calmer & perfect camping days in September compared to April & May camps, where in one day we had frost in the morning, mid 20s by lunch, followed by a glorious thunderstorm & 2in of hail gathered up the sides of the tents!

As for the longer summer camps in August, we’ve had one in 2012 where it seemed to be permanently grey & drizzled for a week, in later years scorching days where, as first aider, I’d spend most of the day handing out sunscreen & dealing with the older teens who think they’re invincible getting sunstroke & sunburn.

As for events & camps in July, I can remember one where we had torrential rain & storms where we’ve been flooded out! And the times we’ve been on the verge of cancelling or actually cancelled mid event due to bad weather has always been in June & July.

September was a favourite time to camp as it’s very much a transitional month from summer. Mostly fair & bright, just cool enough to sleep well, the odd shower but no high winds (lost £1k in tents in 30 seconds in a May Bank Holiday camp once, despite making them more secure than Wormwood Scrubs when we pitched them. There was definitely cloud rotation, on top of a hill with a great view by chance of incoming weather from all sides, we were just unlucky to be caught in the non tornado but rotational wind).

Apologies for a rambling anecdote, it’s been one of those days.
