All Irish stations' means whether be it rainfall, temperature or sunshine divided by the number of stations.

The calculating is very tedious.

How are you doing it? In excel? It could be worth spending some time to learn a programming language or GIS, will be very useful when you go to university.

Just a tip, since it's interesting stuff but you need to watch out for bias when you average like that. If you look at the map of stations they are not evenly distributed, they are clustered and in an east-west band from Dublin to Mayo. Also quite a few stations are along the coast, which will affect how representative they are. Keep up the good work!

Using all these

or just the synoptic stations

and inc Northern Ireland?

Synoptic stations. No cause Northern Ireland is part of the UK and is part of calculating their means for a month.

I understand the bias 100% which is why I find making these stats a bit of a headache. No I don't use Excel, I use a calculator. I'm making it more tedious for myself haha, I should start using Excel when doing this.

How about months with above average temperatures. I thinking about July 2013 when the mean temperature at Shannon Airport alone was over 18c. Or that balmy September 14 and December 15 to mention.

Ok I'll do them also, since you're so intrigued .

Switch to excel right now You could also use OpenOffice if you don't have excel. It will make things much easier for these sort of calculations, and you can do lot's of tests like removing certain stations with just a click.

I think Syran could do worse that learn some basic 'R' programming. Very handy for some serious number crunching, and once you have a workable function written up, then it can be used again and again. Having said that, there is nothing you can do in 'R' that you cannot do in Excel. It is pretty amazing how this basic spreadsheet software can be manipulated for good statistical analysis.
