2018 is completed only up to June. I plan to do 2012 to 2015 too as they have daily temp records in the monthly bulletins too in a similar fashion to the source named above.



Looking at those charts (which are excellent by the way, so easy to read!) It seems that August as we all know is definitely cooler than June and July. Do we know why?
I know it's only 2 year's data but it confirms my suspicions of it pretty much consistently being a crap month!
Any thoughts anyone?

August is warmer than June on average but rarely goes to the extreme side of the warmth as it's a time when the Polar Vortex gradually begins to reinforce itself over the Arctic. It also a time when the Atlantic hurricane season starts to go towards its peak of the year (which is mid-September). One reason I find why September has a tendency to have a "return of Summer" following a poor August is because of the same reason I mentioned just above about hurricanes. September tends to be the peak as described and hurricanes can enforce ridges from the Azores to build up and across us.

Very warm or hot Augusts {2003, 1997, 1995, 1984, 1983, 1976, 1975, 1955, 1947} are rare beasts much like cold to very cold Novembers {2016, 2010, 1993, 1985, 1965, 1925, 1923, 1919, 1915, 1910} especially these days.

Now here's the daily max temp records in Ireland for 2012 to 2015 as promised.









Data from Met Éireann.

On this day in 1965, Dublin and Ireland recorded their warmest March day on record. Trinity College, Dublin recorded an afternoon max of 23.6c.



RTÉ Archives report on this very warm March day.

Quote:
The 28th of March 1965 was one of the hottest March days on record. Hard to believe given the cold spell of the past week.

A RTÉ News report from this day in 1965 shows people flocking to the seaside at Sandymount in Dublin to enjoy the spring sunshine, and pony trekking at Kiltinan Castle, Co. Tipperary.

This clip is mute but the original news report would have been broadcast with live commentary.

Easter Sunday fell on this day 6 years ago, 31 March 2013. Braemar recorded an air min of -12.5c making it the coldest Easter day on record in the UK back to 1961 under a cold ridge of high pressure. Previous record was -9.8c on Easter Monday 1986 (31 March also).

For curiosity sakes, the lowest temps Ireland had during the Easter 2013 period (28 Mar to 1 Apr):

Holy Thursday; -5.1c at Straide, Castleconnell
Good Friday; -1.5c at Knock Airport, Slieve Bloom Mtns (Nealstown)
Easter Saturday; -5.1c at Markree Castle
Easter Sunday; -3.0c at Cavan (Drumconnick)
Easter Monday; -1.5c at Cavan (Drumconnick)

Unless Met Éireann have station data that I don't have access to, part one of my Nov/Dec 2010 cold spells paper is complete (still cannot get over the fact that this extraordinary period of history does not have a detailed paper or peer reviewed journal about it), daily temperature records for the Republic of Ireland as shown by this table.

I'm sorry on the long delay for the February 1986 post - I also planned March 2013 but never got to do it in time for the anniversary.

However, this post is on the snowfalls of April 2008. These were some of the most recent April snowfalls in Ireland.

April 2008 started off on the rather mild side for the first few days with an area of high pressure (central pressure of 1034mb). There was some spells of sunshine, mainly in the south with temperatures in the mid-teens. Waterford (Tycor) reached the maximum high of 18.6c on the 3rd April, the highest max of the entire month.

This little mild interval after a cold second half to March 2008 was very temporary.



The high retrogressed into the Atlantic and then up to Greenland by the 5th April forming a blocking anticyclone of 1043mb to the south of Greenland. This forced the winds into a northerly direction. With cold air filtering down from the northeast combined with the strong Spring sunshine, the atmosphere gradually became unstable forming scattered wintry showers later on the 5th.

There was consistent troughs in the northerly airflow sinking southwards through the day on the 6th resulting in frequent hail, sleet and even snow showers especially in the north though sunny spells in between. Nevertheless, it felt very cold in the northerly wind as gusts were moderate to fresh in nature reaching a max gust of 107 km/h at Malin Head.

Ardfert (Liscahane) and Derrygreenagh recorded minima of -2.3c on the 7th but lower minima were recorded in April 2006. Minima weren't particularly low due to the gusty northerly winds.





The wintry weather delayed an upgrade of the M50.

Fortunately, there was less than an inch of snow for the vast majority so conditions weren't overly bad and places like Sally Gap were fully passable. Any snow that did fall overnight from the 5th into the 6th all melted by the late morning hours.

April 2008 afterwards tended to be very showery so it was a classic month for April showers.

An article I read over the weekend was saying, according to UK Met Office records going back 30 years, snow is far more likely in April than November. It makes sense as I can remember quite a few snow falls in April, but would struggle to remember more than two or three November snowfalls over the years.

Yes snowfalls are more likely to occur in April but snow is more likely to stick or lie on the ground in November in comparison.

I've looked through lots of old weather picture threads with snow pics today and my god, some of them are absolutely unbelievable especially those of frozen lakes/rivers in late 2010.

I remember this day (10 April) well in April 2011 (one of the nicest months I've seen in my life) with lovely spells of sunshine in Dublin and temperatures touching the high teens to 20c. Malin Head recorded a maximum temperature of 20.8c on the day which is its April record high temperature back to 1955.

Easter Sunday weather records for the UK (2000-2018).

Still working on the February 1986 post and hopefully get it finished today. If not, I'll post the daily minimum temperature records for Ireland in 2012 and 2013 (like I did with the max temps).

Well, it does not look like happening so here's the daily min temp records for 2012 to 2015 (thought I'd add 2014 and 2015 in too). Will post the 2016 and 2017 ones another day.
