Lying snow on the Dublin mountains right now!

I haven't looked at the stats to back up my opinion so maybe I'm talking s... but I think August has become more and more Autumnal in recent years. Seems like they were better overall 10+ years ago.

This is from August 2019 I took it from Baggot St but I remember it being day after day of this stuff. Today had a lot of this black cloud where I am.

Waiting on 1991-2020 averages to come for the Republic in July. In terms of Northern Ireland (N.I.) from the stats I've gathered, going from 1981-2010 to 1991-2020, it seems N.I. has had slightly warmer summers (very small difference in both mean max and mean min), wetter summers with June and July seeing a fairly significant increase and sunshine has stayed the same. I was kind of surprised with not seeing more of an increase in mean min and a decrease in sunshine because to me it seems we have had cloudier summers resulting in less of a temperature drop overnight. The Northern Ireland data seems to say no to this.

It should be noted though that if I take Augusts of the 1990s out of the equation, there has been a reduction in sunshine. The 1990s tended to feature an abnormal run of warm Augusts although not all were dry - like the exceptional humid and very warm August of 1997 was extremely wet in the south. Of course, August 1995 stands out big time breaking all kinds of warm, dry and sunshine records. Junes weren't the greatest for the most part in the 1990s with 1990, 1991, 1993, 1997, 1998 and 1999 all being quite or very poor whilst Julys were very mixed. You could say the 1990s favoured more 'backloaded summers' compared to the 2010s which featured a fair few front-loaded ones. I have mentioned before that it seems since this run of somewhat better Augusts from around 1989/90 to 2003, we've had our fair share of mundane, often boring or very dull and zonal wet Augusts with 2010 being the driest and sunniest of the lot but on the cool side.

The only 1991-2020 stats I have to compare in the Republic is sunshine for Dublin Airport which July saw a big reduction from 81-10 to 91-20, almost 10 hour loss. June has seen an increase whilst August has seen a decrease but not as large as July. I am intrigued to see how the trends are for other places.

Augusts can often be cloudy (and very humid) but from a weather lovers point of view, it also is most volatile of all the summer months. And something I have noticed is that the evening twilights during the 2nd half of the month are weirdly beautiful and 'lingering', much more so than their pre-solstice equivalents.

The planet Mercury is visible now low on the horizon looking West northwest.

While its a cool night out its a beautiful night out, still blue skies out west here in Castlebar. perfect night for watching out for meteors after.

It certainly was a lovely evening sky out there Oscar Bravo with a nice lingering twilight and it definitely was a cool one. Was out along the banks of the River Moy this eve and it felt like an evening in early March.
Temperature read 2c when I got back to the car at 9.45pm. I see that Casement registered 1c in the 10pm reports with a number of other stations at 2c.
Not a bad day here at all once the early showers died off but I personally wouldn't mind seeing a bit of warmth returning and some bit of nature coming into these May evenings.

River Moy, Co. Mayo this eve.

brrrrrrr on 6th May 2021

All my Summer bedding plants are in my shed at night. Normally they are out day & night by now. Gardeners nightmare!

This golf club is next door to Casement.

Might only last a day!

Glenties in Donegal is lowest ever at -5.6c

Met eireann stats reported -4 at Mt. Dillion at 6am.

Now as we know could be out slightly but it will be near enough to this.

That's rounded. I was wondering where they got -3.8C from, as Mt Dillon isn't on the synop or observation sites I usually check to get an early exact value from although even they can be off sometimes.
