Why do you think they are rediculous? They are positioned for specific purposes. If you are involved in aviation or marine activities they are pretty logical! :rolleyes:

Sorry, I meant from a population point of view.

I do accept that the stations go back decades (maybe over a 100 years in some cases?) and have excellent historical data. I also realise that from a marine and aviation point of view they're important. I wouldn't advocate that they be closed.

But at the same time the vast majority of the Irish people aren't involved in marine or aviation activity and don't live near Malin Head or Valentia for example. And although DA is relatively close to the city centre it's not really representative of Dublin as a whole and weather apps and sites always feed off this station which is annoying (though Phoenix Park is thankfully being used more now - but it's only recently that this has happened and I'm not sure if it provides enough data for apps and sites to actually feed off).

Times change and stations are needed where people are living and working. It's a bit like saying Dublin Bus provides a brilliant direct bus service from Malin Head to Valentia that goes back decades. That may be well and good, but if the route isn't relevant to anyone anymore you have to ask questions (a silly metaphor but hopefully the point is clear).

And although centre locations suffer from heat island effects etc, the population needs to know what real temperatures are actually going to feel like (so long as a station isn't placed in a completely ridiculous location in direct sun beside a window for example).

On some nights over the past few evenings Dublin CC has been sweltering. I'm not sure if many people in the city cared whether this was because of UHI effects or concrete or direct sunlight etc - they just want to know how warm it's going to stay in the evening.

It always seems to Heathrow that records the daily UK max during summer heatwaves - a place with acres upon acres of tarmac, car parks, terminal buildings, hangars and warehouses with vast roofs all radiating heat and not much soil to absorb the sun, the place with five terminals is more of a city than an airport ............. just a thought.

Just noticed yesterday was the first time since July 4th that no Dublin station exceeded 20 degrees. If I was told at the start of the summer that we would have 11 days in a row of above 20 degrees in Dublin I would have taken that.:)

In Donegal for the past week, guess I'll change my location to make things easier

Stunning model runs again this morning, could be a record breaker of a month if that ECMWF run is accurate

The past week...

Everywhere bone dry apart from some light precip on north and western coasts.



Sunshine over 200% above normal everywhere.



Poorly drained soil in the southeast now requiring over 70mm of rain, with no rain and only warmer conditions forecast for the coming week.

Was 21.8C here yesterday in the sun. Anywhere south of Cabinteely would have easily broken 20C as that seemed to be the approximate start of the sun (I was driving all over during the day).

Yeah, drove up from Wexford at 7am yesterday - the sun seemed to disappear as I hit the M50!

I wouldn't doubt you for a second I was just going by the official ME stats definitely felt warmer than 19 at 6pm yesterday in north Dublin.

24.5 here in Waterford now. Feeling quite warm with a couple of cooler breaks under the passing cloud.

Do we record sunshine in only four locations

Absolutely, hit 21 here at 5.30 and was above 20 for several hours and I'm further north and higher up than Cabinteely.

Got to 22.5 here just now, but cloudy again and has eased back to 22C.

The sun only came out about 5.30pm or later yesterday in Dublin from what I observed. Felt really balmy right up to 10pm then with some late sun heat coming through.

Today is a mixed bag so far in Dublin. Sunnier around 11am, a cloudier lunchtime and now getting sunnier again. If it the sun penetrates more widely, I wouldn't be surprised to see 24-25 in the greater Dublin area later this afternoon.

I'd suggest the vast majority of people do not really need to know precisely the current (or past) weather conditions? Whereas having the current weather conditions for, say, an airport is vital (for safety, etc., etc.).

Does the average Joe really care if it 24.9c with an RH of 65% or 26.5c with an RH of 50%? Probably not?

Also bear in mind that the weather station is not going to 'give' you the forecast (of what real temperatures are actually going to feel like...or anything else) and/or any forecast is not going to be specific to the vicinity of the weather station...ME issue a forecast for the Dublin Area (and not for a localised area around a particular weather station).

Limited resources and all that!

I do appreciate where you are coming from compsys! If I was in charge I'd cut child benefit and put an official weather station in every Dublin postal district!!!

Was sunny here but has now clouded over...hopefully temporarily. 23.7c atm.

Here in Dun Laoghaire its what you could call a very benign day. Partly cloudy with haze, soft sunshine breaking through, 20C with 65% humidity and a light SE breeze. Ideal for a few days, but looking forward to beach weather again later in the week!

Knock Airport too (256% above average). Not sure why it's not on the map.

Thanks Maq for all your contributions in this exciting period of weather!

Some great Sea Temps at the moment. 18.5c at M5 buoy off Wexford Coast. would imagine it would be a quite a few degrees warmer in estuaries and sheltered bays.

I can testify very unscientifically that the water in the bay between Lambay Island and Irelands Eye at Donabate is very pleasant!

I do accept your first point but not sure about the second point.

Research shows that oppressive night-time temps have a far worse effect on people than oppressive day-time temps. So when DA is saying it's a cool 7 or 8 degrees at night but it's a sticky 14 degrees in the city (has happened before) I do think that's an issue. I remember during the June warm spell a friend of mine (who has absolutely no interest in the weather) posted a picture on his Facebook from his iPhone early one morning showing Dublin at 4 degrees with the joke heading 'Dublin Freezes!?'.

But yes, there's resource issues and a station can't be placed everywhere. It's just unfortunate that the new station (because of its location) is sometimes very out of kilter with the rest of the county (even though I now accept it's giving accurate readings for the exact location it's in).

I can tell you that The Upper Lake in Glendalough was very comfortable for swimming in last Sunday!

Drought conditions in the south east. It was on the farming independent today, that wells are going dry in the south east, grass growth has come to a standstill and a second fodder crisis could be underway.

I wish the high would go further north to the point we get a little bit more instability with thunderstorms.

Agreed...but...that's at the time of the 'event' or after the 'event'.

Temps may well have dipped to, say, 7c or 8c at DA on a given night, but you would probably find that ME, the day before, may have forecast minimium temps of, say, 12c for that night (all hypothetical of course).

What I am trying to say is that ME are not and do not forecast temps for the greater Dublin area on what temps might be expected at DA...if you know what I mean?

I think the main or part of the crux of your issue is the fact that when you look at the ME website and see 'Dublin' on the strap bar/top of the page it reports current conditions from DA. I would agree that this is a bot misleading and ME should probably use Phoenix Park for this data.

I think a point being made is that the "official" stations do not represent a county - even if they are not in an "unrepresentative" place like some headlands and airports.

For example from my vantage point in suburban built-up foothills I could say

"the sun came and skies cleared about 2pm yesterday in Dublin with temperatures rising to 21c at 5pm. It stayed clear for the rest of the day and by 10pm there was a noticeable cooling off.

We have had no "sticky" nights at all in Dublin. "

Today Dublin has had long cloudy periods interspersed with several good clear periods and the temperature peaked at 23.2C at 4pm.

It's now 21.7 in Dublin

Early next week looking very warm and thundery on the 12Z GFS.

It's FI, but just an example...

(these temps can be higher by a couple of degrees in reality)

Yes, that's right. Would be great if more weather apps and sites used PP too (in my opinion, others may disagree).

Over on the DA micro climate thread FWVT was saying this is the fault of the weather sites themselves and not Met E. But I don't think Met E currently provide enough data for this to even happen. For example, the latest reports page doesn't yet give weather conditions for PP (as well as a few other stations).
