Warmest hour of day

danielcork1

interesting question that poppped into my head sitting on the patio: what is the warmest time of the day in Ireland for spring/summer? for once, i cudn't find anything on google so i thought id ask ye! Also, would the warmest hour vary with seasons, etc. or remain pretty much constant throughout the year?

Snowbie

The sun is at the highest point in the sky around noon, so id say anytime between 12-3pm you would see the warmest temps. Also depending on airmass this could change.
I have recorded my highest temps in the late afternoon/early evening.

Away from coast it is usually about mid afternoon, probably slightly later as you go through summer.
A run down this month so far to 14th
GMT times, add an hour for summer time

11-12 1
12-13 3
13-14 6
14-15 1
15-16 1

Near the coast subjected to see breezes, it is often mid morning or earlier, or as Snowbie says, late afternoon/evening after see breeze has died down.

While you didn't specify winter, the sun is so weak, it has little bearing on daytime temperature, and it is more to do with airmass.

As far as I know, the high noon (when the sun is at its highest point) in Dublin during summer time is at about 13:24, give or take a few mins, rather than at midday. Makes a big difference. It is this late due to a) 1 extra hour because of DST and b) the other 24 mins (I'm sure I'm wrong there) due to our longitude in relation to Greenwich.

I'd say you're right on all counts.

Not sure what you can conclude from them, but probably typical for site subject to see breeze. I'd say much more consistant at an inland station and would be interesting to see.

And specifically to give my thoughts, I'd say generally later by an hour or 2
