Su Campu

What is the climatalogical average temperature for the 5 stations?

M.T. Cranium

Su Campu (and others), DE was just mentioning to me that you can find slightly different 1961-90 "Normals" for various stations in Ireland on different tables in the met.ie publications. He is in the process of clearing this up with Met Eireann, but in any case, the averages that he gives us would be within 0.2 of any other averages for those stations if you happened to look at different sources than he's used. I just looked up the May values and found his value of 10.4 to be accurate from the first values I happened to find. It's probably an even longer story than I just made it seem to be, but in any case, we're predicting an absolute value that will be based (for verification) on what's reported in the climate summary when it appears, so that's the standard and we think the "1961-90 mean" we are giving out is accurate enough to give people a good starting point for their prediction.

So 10.4 it is for May (if you look them up you'll see they are all close to that value or a little under, except for Shannon which is 11.4 if I remember right).

Just a reminder, entries are accepted without penalty to the end of today, after which a slight penalty applies for entries on the 2nd.

Is ther something special about 11.1 that I missed out on???!!!

M.T. Cranium

Seems that way. Note that the current forecast comp thread is now "sticky" and easier to find.

The first seven days of the month have left us at these values:

mean temp 9.3 C

rainfall 73% of normal

sunshine 90% of normal

In general, the east has been wetter and cloudier, the west closer to average if not a bit above for sunshine.

pauldry

yes was thinking tis been a bit chilly . today was a lovely sunny day here but though i wore the t shirt i still had the goosebumps. next week will be chilly too. someone may do very well this month with their low temperature prediction.

and on the 8th day, the combined mean value of the 5 central Met Eireann stations remains at 9.3c, which is in and around normal for the first 3rd of May.

Chart showing mean maxima & minima for the first 8 days of May at the 5 met eireann stations:




Like April, the west is a little warmer than the far eastern section of the area regarding daily maxima, although mean mins are fairly uniform across the country so far.


A quick look at how the annual mean temp is doing at the 5 met stations:



On the rise at last, but still 1.07c below normal for the period, and even cooler than this time last year. With temps forecast to be close to or a little below normal for the coming week, I would be surprised if the we got within the 0.5c-1.0c anomally by this time next week, but I'll let ye know the story!

Forecast chart for the coming mid-week period:



Ridging to the NW continuing to steer down winds from a northerly sector so feeling fresh but pleasant enough in just light to moderate winds.

Min temperature yesterday at Casement was -2.0c. This is great news!
