Saharan dust moving up over the country over the next few days

I'd say today has fecked up most people's max temp prediction for September 😅 Currently 27.5c at an official station.

Wonder could that have any affect on temperatures? Though I presume any affect would be negligible.

Are we allowed make silly slightly weather related jokes?!

I hear there's a new film coming out about a shop in the Sahara desert.. It's called Store in a Dry Place.

Beautiful day in Dublin - blue skies, warm sun. But once again the wind is there as it has been for months now. It's very windy in Clondalkin (to an annoying level - blowing things around), whereas it was only breezy in Lucan.

Here's where the Valentia 27.5C stands in Ireland's warmest September days on record in terms of maximum temp.

01 Sep 1906 29.1C

07 Sep 2021 29.0C

05 Sep 1991 28.4C

02 Sep 1906 27.7C

04 Sep 2023 27.5C

12 Sep 1959 26.7C

10 Sep 1959 26.6C

03 Sep 1991 26.6C

06 Sep 2016 26.6C

05 Sep 2016 26.5C

02 Sep 1991 26.3C

16 Sep 2003 26.3C

There was a 28.4C on 1st Sep 1961 at Gurteen and there was a warm enough airmass to support the value but it was several degrees above other stations so I have not counted it.

27.5c is the daily max going on 5pm. 1.5c above forecast. Tomorrow will be interesting.

Edit: Unless Shannon Car Park does something spectacular between 5-6pm..with a sun declining in the sky.

25 in Sligo now from 12 at 10am. Some jump over the day.

Tomorrow may be a slightly cooler day overall. Thursday and Friday may well be the peak of the warmth so a 28C is possible on those days.

I think one thing has been put to bed today. That you need bone dry ground to get the highest temperatures. Ok we would probably be 1c higher with August 2022 type ground.

But a few dry days will suffice to get you very near record temps. I'd go with a max of 28.5c somewhere tomorrow. We'll be starting from a higher base with high nighttime values also.

No drying in South Wicklow at all, other than in the direct sun. My covered patio is still wet with a layer of dew and the grass is still wet. Washing on the line still damp despite being out since 10am. Crazy humidity here

Tomorrow more cloud so mid twenties and probably 26c max. End of week is chance for 30c if forecast remains on par.

27.5c is amazing when you think of it.

1980, 1985, 1986, 1987, 1988, 1992, 1993, 1994, 1998, 2002, 2004, 2007, 2010, 2011, 2012, 2015, 2016, 2017, 2019, 2020 off the top of my head never had a May, Summer or September reach it. That's 20 years out of my 47.

GFS 12z keeps this warmth going almost uninterrupted right into the 3th week of September with another 2 reloads of high pressure possible. If this was to verify then a record breaking September could be possible. I'm off to Malaga on the 18th and the GFS is showing a plume of heat pushing northwards out of Africa and through Spain and on into France and then back towards the UK and even Ireland, courtesy of a cut off low just off the Portugal coastline. If this was to verify I would be looking at temperatures well north of 30C on the 18th with 25C still possible in Ireland, however this is likely an outlier.

The highest min of December 2015 was 13.4C at Glasnevin on the 19th. The highest max was 16.6C also at Glasnevin on the 18th.

There could be some thunderstorms about as the week goes on. I think that GFS run is off on one, but then again if you think about the weather over the last to or three years we could end up with a prolonged dry spell. Just imagine if by the end of September farmers are desperate for some rain again.

This is make up for that awful wet summer and we are now ending with potentially the warmest week of the year in September. Next week obviously won't be as warm but it could still reach 20 or 21C on several days. However the 12z is on a bit of a heat wobble but everytime we change weather patterns these days they seem to stick around for ages, not just a week or 2.

May 2012 had a 28.3C at Ardfert, Kerry. The second highest May temp on record and just happened to be the same site that also achieved that national May record of 28.4C back in 1997. This was the highest temp of the "summer"/year.

July 2016 had 30.1C at Mount Dillon. A very random and oddball 30C. Most Irish 30C typically occur during "classic" or very warm, dry and sunny summers. 2016 was not one of those.

June 2017 had 28.6C at Phoenix Park during a heatwave mid-month. That summer quickly turn for the worst after it.

June 2019 had a 29.7C at Ardfert during an exceptional push of heat (in terms of upper air) from the south but was heavily affected by an inversion beneath. This until July 2022 was the only time 20C at 850hPa has likely been in Ireland.

The others you would be correct on.

I remember Mt Dillon in July 2016 alright. Few warm days that summer. 25c for a few days around 15 August. And September 6th, I think, reached 26c.

Yes May 2012 had a nice warm spell and 28c reached.

I hadn't 2017 or 2019 in my memory bank at all.

What I was thinking of. Malin breaking it's daily max back to 1955.

https://www.boards.ie/discussion/comment/121069086#Comment_121069086

We got 25c as late as 20\21 September in the west in 1998. Also the week of the 14-18 September 2003 reached 25c also.

Meteorite58

Got up to 26.4C here near Tralee out by the coast, 21.6C atm. A calm balmy evening , just back from a walk along the pier in Fenit, very dull and overcast this evening, can feel the warm air trapped in, going to be a warm night.

Fairly disappointing evening in the end in Cork, yeah it's warm but a lot of hazy cloud and a strong breeze.

Yes indeed, all to be expected with a warm humid Southerly. We never fair great in Cork with onshore winds
