Interesting that we are below average given it has seemed subectively to be an ok weather month.
From my solar output being above estimate and also my gas bill can I hazard a guess that it has been the night time temperatures that have pulled the cet down?
I think that's the case, with minima being comparatively lower than maxima.
On the whole I've really enjoyed this September, plenty of sunshine, quite dry, decently warm by day and refreshingly cool by night.

4C this morning, 18C this afternoon. It's that time of the year where we can see some very large diurnal temperature ranges under clear skies...
Yeah, although it's never usually on a par with Feb/Mar/Apr/May, due to the generally higher humidity, increased likelihood of cloud and latent heat left over in the Autumn.
With that being said, I love big diurnal ranges at any time of year.

Thanks guys!

The thing I don't get about the Greenland melt "theory" (is it just a theory??!) in relation to the cold pool is why it is so localised to the south of Greenland. If it is caused/influenced by cold freshwater ice-melt, then wouldn't (shouldn't?) there be cold SST anomalies all around Greenland?
I'm not coming at this from any angle, by the way. I'm genuinely interested.

The lighter half of the year isn't the warmer throughout, there is a bit of overlap. The darker half (Oct thru March) is colder overall, obviously, but October is typically warmer than April, despite the comparable lack of sunlight.Now it's indisputably Autumn that it's the equinox, meaning its both Autumn by the meteorological and astronomical definitions.
Out of curiosity I know the soltices are sometimes referred to as mid Summer and mid Winter. Does this mean that Spring and Autumn are in a way parts of a two season model of Summer and Winter (the lighter/warmer half and the darker/colder half of the year) and therefore in a way because we're now at the equinox according to this two season model it's Winter now with the Winter solstice being mid Winter and the Spring equinox being the end of Winter and the beginning of Summer then the Summer solstice being mid Summer then back again in a years time to the Autumnal equinox which will be the end of Summer and the beginning of Winter. Anybody ever thought about this. Will be interested in your thoughts. What I'm thinking is that Summer and Winter are the major seasons with Spring and Autumn being merely lesser versions of the other two hence why the solstices are often in folklore referred to as mid Summer and mid Winter respectfully. What do you think?
I get what you are saying, though. Spring and Autumn are often just seen as transition seasons, rather than fully fledged seasons within their own right. In the UK I'd suggest that they are as valid as Summer and Winter, given that Summer like or Winter-like conditions can be hard to come by even in their own respective seasons!
However, in many places around the world, spring and Autumn are actually comparatively short, with abrupt transitions into/out of Summer/Winter.

'Japanese giant hornet'
The one below has been tamed on average annually these kill 40 people in Japan.
Seen an interesting documentary on those things. They attack honey bee hives, but the honey bees can kill them by completely covering them in a ball, causing the hornet to overheat and die.
However, only the Japanese honey bees have figured out this defence. European honey bees meet the Hornets one-on-one, and it never ends well for them.
You've got to marvel at the evolution behind such a creature, and how purposeful it looks, but if one is ever in my immediate vicinity I'm either running away or it's getting squashed. Zero middle ground.
-
Not seen many wasps at all, hardly any. Bees, too. Only really seen them from around August onwards on lavender.
-
13.2c to the 21st
0.7c below the 61 to 90 average
1.3c below the 81 to 10 average
Is it stuck on that?!

Polar maritime air will experience reduced modification, but that will likely just mean slightly colder rain.
I'm not sure, depends where you are I suppose. I got a few good snowfalls last winter from PM air, and that's with the SST cold anomomly a bit warmer than it could be this Winter.
-
I found an archive of monthly N Atlantic SST anomalies on the Icelandic Met site: gives a nicely detailed picture rather than the broad brush charts we have looked at so far.
Some have commented on the similarity between this year and 2009 - an August comparison for both years below.
2015
2009 Appreciably lower SST's between the UK and Iceland in 2015 than 2009. Also, SST's look lower overall almost everywhere this year.
Interesting.

I can see the positives of all seasons. The sky felt wintry today and it was actually kind of nice in a strange way. Like the type of day that you get all nice and wrapped and then go home and put the fire on. Also we've had some lovely crisp autumn sunshine recently.
Just need some snow now.
Fully agree. I'd find any season tedious if it persisted year round. I like the variety. I couldn't imagine having SAD, I'm honestly not fazed in the slightest by the changing daylight.

April is the recent form horse

We are now at the point where the sun has the same intensity as it does in March.

You can really notice how much lower the sun is in the sky now, adds to that increasingly Autumnal feel!
Was going to say that, Nick. The sun itself has far less intensity, too.
I know what you mean about the Autumnal feel; despite the pleasant warmth you can't help but notice the longer shadows and lower sun. It's gorgeous out there today, I love warm sunny days at this time of year.

Might be related to the persistent ridge along the west coast. That could be driving the Arctic air down into Canada and into the central and eastern US, increasing North American snow cover maybe?
Maybe, but does that not make much of the western half of North America warmer and drier in Winter? Saying that, snowcover can still probably persist there in spite of the positive anomalies more readily, due to the higher elevation in the lower 48 and higher latitude in Alaska. Cold in the east, especially further south, will obviously help retain snowcover in areas that may not/don't usually sustain it as well, such as Alabama, Georgia etc.
Well, that's my simplistic take on a complex matter, anyway!
-
August was ranked as the 14th lowest snow cover for the northern hemisphere (close to average for North America, 9th lowest for Eurasia).
http://climate.rutgers.edu/snowcover/table_rankings.php?ui_set=1
It seems like North America in recent years has been near/above average, but Eurasia has been below. Is this accurate? If so, why?

12.5C, please.

Not sure which comment said' we could magic up some extra daylight' from ?
I never said there was such a comment, I was saying that I got the impression that some people go on as if it's an actual possibility.

Changing the clocks is discussed every year, but nothing ever changes and it never will in my opinion. I'm glad though, I think the system we have is fine as it is. We get so little daylight in mid-winter that there will never be a perfect scenario.
Agreed. The way some people go on you'd think we could magic some extra daylight by simply changing the clock.

Absolute stinker of a day. Not a day to have a job working outdoors...
-
For me it's the first cloudy evening at sunset around this time of year when the longer nights hit me. I obviously notice it much earlier, but it tends to hit home around mid-August. That night was tonight.
Around a month ago I could have washed my car at half 8, tonight I was driving it with the lights on! -
It's weird, it's not actually been that warm, or felt it as such, yet I've found it quite uncomfortable sleeping at night. Why is this? Have dew points been high recently? Humidity?
Usually when I struggle to sleep at night it has been very warm during the day, not so recently.

Come on guys, "miserable season" this, "depressing season" that...just enjoy the summer, will you!

I really noticed it this evening. I went to the shop at about 20:30 and the sun was barely above the horizon. Unfortunately, summer's precious time is now running out as we move closer and closer to the miserable season. Hopefully the weather will play ball during the latter days of August and September, before it's too late for any significant warmth....
Do you not find anything appealing about the Autumn, Scott?
Whilst in a way I'll be sad to see summer go, I can't mourn it's passing.
The same goes for every season; variety is the spice of life, and although I may miss certain aspects of any season that's on its way out, I look forward to the unique features of the upcoming season.
Truth be told, I'd hate to live in a place without seasons. I might enjoy it for a few months, but I reckon the novelty would start to wear off after that. I do genuinely feel sorry for those that experience SAD.

I'll go for 9.7C, thanks.
