A new general discussion thread for the new season that is upon us.
Well we won't have much of a winter this year. This very warm September has effectively aborted it while its still in the womb imo. Autumn this year oct 2021- March/April 2022.
Personally I'd like 2 main seasons. Summer and Winter. Two short transitionary seasons of spring and autumn.
Spring April and May, Autumn October and November. Four months summer with a September like this. Four months winter with March like 2013 and 2018.
I'm sure there are places in the world with that climate, some mid lattitude continental areas?
Meanwhile despite being an anomalously dry and warm month to average, it has also been an often cloudy month (which is part of, not the only reason, why I express hatred for it). The limited stations' sun data I have are only around 40-60% of their average September sunshine with Cork Airport at only 58.7 hrs which is currently below its cloudiest Sep on record (2016, 68.4 hrs) but I expect it to go above that. Dublin was less than 50 hours before last Sunday, fortunately this past week has had some reasonable days with sunny spells and now almost 80 hrs which is still some way below average but an improvement at least.
I don't particularly want that either (though i don't mind the odd day like that every now and then) but I do like the seasons to feel seasonal at least
Sometimes it feels like the seasons are becoming more homogeneous to an extent anyway and I certainly don't like that.
Unusual to see burnt grass in late September. Today Could be like a July day during a drought.
Another beautiful day in Dublin. September has been superb, warm and dry nearly the whole month. It has felt like summer to be honest, even heading out on evening stroll this week you would have gotten away with a tshirt
Not rain and gales anyway, no thank you
Best Post from him in a long time why? Because it tells you what you want to hear?
Doesn't mean there will be more warmth anyway, though i wouldn't be surprised if there was.
We have had effectively nearly an extra month of summer this year,what more do people want?
another beautiful warm September day. Make the most of it today is the last of the 'summer warmth'.
Was a gorgeous balmy morning here in Dublin, went for a jog on Clontarf promenade and there wasn't a hint of wind. Feels like being in a different country.
Brilliant news, thank you so so much. Best post from you in a long time.
Another lovely warm sunny start to day here in South West Dublin 😎,cracking conditions for late September
Beautiful balmy morning. Can we keep this going into October please!
At the Airport, September bet the preceding August in terms of mean temperature in 1985 and by a full degree (13.5 Aug vs 14.5 Sep). It also occurred in 2011 (13.5 Aug vs 14.0 Sep).
At Phoenix Park, this occurred in 2011 (14.2 Aug vs 14.4 Sep). I currently don't have PP monthly data before 2003.
At Casement, this occurred in 1985 (13.4 Aug vs 14.2 Sep), 2006 (15.4 Aug vs 15.5 Sep) and 2011 (13.6 Aug vs 14.0 Sep).
The temp has reached 20º or more on nine days so far this September, which beats the number of 'warm' days in August.
Looks like September could end up (ever so slightly) warmer than August in Dublin (after April was colder than March).
Surely that hasn't happened before?
My station at Arklow has reached 22c today
the incoming colder weather also may not last that long, temperature anomalies look like going above average again later next week. The models for October look fairly mild overall with high pressure possibly coming back in about a week to 10 days time.
Oak Park Carlow at 15.8c. The cooler air will only hit midnight Monday 27 September. You have 27, 28, 29, 30 to bring down that average. It'll be 15.1 or 15.2c. Record stuff. We're just getting some north Atlantic air too. Probably slightly below normal. We're not getting a northerly blast, so not going to make a huge difference to the mean.
Also late in the month. You'll have 26 days by 15.8. And maybe only 4 days with 11c mean to lower it.
Dunsany is sitting at 15.3C for September, that's 2.3C above average for the time of year. August finished on 14.9C so with the cooler conditions over the next few days I suspect the mean temperature will fall back into the 14s. As for the CET it's going to be tough to get that under 16 as it is currently at 16.8C and only a week of cooling left on the table.
Rainfall for September is currently very light at only 8mm for Dunsany but I suspect that will get a big boost from Sunday and into next week.
Hopefully it'll come back for some of October. A few weeks of 15-18c.
Amazing. Some Met Stations above the July average up to 23 September.
A big change is finally on the way from Sunday evening to unsettled and chilly. The drop in temperature could be a shock to the system as we haven't had many days cooler than high teens/low twenties over the past 3 to 4 months. But it had to happen soon as summer style temperatures can't go on indefinitely away from southern Spain during the autumn and winter.
I long for cold crisp days and jumping in puddles. Each morning I read MT's forecast with hope only to be disappointed. I'm not a mild weather lover and it feels like it has been this way for an eternity.
I can’t get over how consistently mild the nights have been all summer and early autumn. Still 16 degrees in the west in plenty of stations at midnight.
I believe in 2010 that was partially the result of some unusually cool nights through late August and grass mins were around freezing - which can destroy the chlorophyll in the leaves quicker. That was the other thing about 2013, there was little cool weather to be had through September and October 2013 and any frosts or cold nights that did occur in November weren't severe or notable like in 2010. Balance is key!
2010 had leaves changing colour in late August. Some said it was drought. But the same didn't happen in 1995 which had far higher soil moisture deficits.
Good point @Squeaksoutloud. I had forgotten about them somehow. 2013 was probably the last spectacular season for them and this year has had some similarities with that in terms of how the weather has gone.
Typically, the leaves of deciduous trees have around a 6 month life expectancy. Many trees here remained bare up to early to mid-May this year which was similar to 2013. So the leaves could stay on trees later than usual into the autumn lasting through November if winds remain generally calm.
Drought or prolonged dry weather can be as much as a negative impact however as strong winds so some rainfall at times would be good for the leaves.
We may get a great 'Fall' season of colours if the calm settled weather was to continue into October. Always a good added bonus.
Consistent signals that warm temps will become a feature as we get deeper into October (after an average start)
September is not a wet and stormy month but this one has been more calm than usual. The national mean wind speed for this September is currently running at 6.5 knots which is actually record calm (since 1981 at least)! The current calmest September is September 2014 which had a national mean of 6.8 knots.
The recent days have tended to be windier however and the national mean is steadily rising. Yesterday was the windiest day since August 13th nationally speaking.
Here's how 2021 compares on a daily basis to 2010 (a record calm year for many) as of 22 September.
While it gets cool from Sunday evening it may not last. Even the cold of Sunday will be around 14c days and 9c nights. By Wednesday it could get mild again. Think October will continue the warm trend but probably 18c on the warm days but there will likely be more of these than not. Bar the odd storm.
