Biglad

-9.0c, clear

Car was showing -11c, but that would be to close to the ground for a proper measurement would it?

ccoyle

-16.5 in convoy/raphoe a while ago

paulaa

-3 in Wexford but feels a lot colder. It's a lovely clear night with a huge moon

Harps

-16C in Kilygordan now as well, Foxford's record could be beaten tonight by the looks of it

It definitely feels like the coldest day yet, even with a heavy coat the cold just seeps through to your body as soon as you step outside

Pangea

Its a rough guide I think really, sometimes its inaccurate as DeepEast told me the heat gets trapped in the bumper a lot too and with the tarmac it can read inaccurately sometimes.
Also if you just start the car the tempertures are not accurate it has to be moving for a while, the last day when I started it it said 14c because the sun was shining and it wasnt moving so it wasnt getting any air exposure.

That's all true about these car temperatures, Afaik official air temperatures in these little huts are taken at a certain height i.e. 1.6 meters or something sure somebody on here will know more about that, hmmm, wonder what my friend Mr. Google has to say about this...

Wiki;

Meteorological observatories measure the temperature and humidity of the air near the surface of the Earth usually using thermometers placed in a Stevenson screen, a standardized well-ventilated white-pained instrument shelter. The thermometers should be positioned 1.25–2 m above the ground. Details of this setup are defined by the World Meteorological Organization (WMO).

My two outdoor sensors are mounted at about 1.4m above ground.

1.2m is the offical height used by met eireanns thermometers.
NRA has air tempertures and ground tempertures on their site , Im sure they are pretty accurate.
I have mine just between 1.2 and 1.25m

Biglad

-9.5c now, think we might break personal best for this spell which is at -10.0...

Lumi

-8.6C in Galway city

Pangea

-8

Harps

Kilygordan back up to -14.4C, guessing it must have clouded over

Deep Easterly

-10.8c at the mo.

That is the more or less the right height for measuring temps/humidity.

I don't think the NRA station up the road from here has its thermo at set at this height though; it seem more like it is somewhere between 4m and 6m. Although I have only driven by it. Must stop an take a closer look the next time.

Recovered from that midnight blip - but is there enough time???

That equals the record I think! Can it nudge down a bit in the remaining hour?
