I don't know much about how they go about recording weather at Exeter
Airport but it has occurred to me that the temperatures they report are
always about 1C - 2C above anything else around here in south east Devon at
an equivalent altitude.

The airport is about 6 miles from here and I drive by it everyday. The car
thermometer confirms my own weather data which shows that the temperature
does not change between here and the airport by anything more than 0.5C; yet
I can never get readings as high as the airport's readings - electronically
or manually.

Nick,
The reported temperatures on the METARs are consistent with
those recorded at the Met Office today.

The temperatures are consistent with those that I record in Teignmouth
(unofficial), Teignmouth's official temperatures and an adjacent site
at Holcombe http://www.dawlishweather.co.uk/

One possible explanation is a mini Fohn
(http://en.wikipedia.org/wiki/F%C3%B6hn_wind) effect created by mild
moisture laden air descending on the Eastern side of Dartmoor, when the
winds are fast moving from a S to SSW direction.

It's no surprise to me that Teignmouth recorded the warmest temperature
in the UK on Friday & Saturday.

Exeter Airport is almost due North of Teignmouth.

It's happening again!!

At 19:00 today Exeter Airport is reporting 14C (and has been since 14:00).
On both my mercury and electronic thermometers I can only manage 12.8C.

Currently at 19:10, 12.7C, RH 89%, DP 11.0, 1000.8 mb (R), Wind 12.0 mph SW
gusting 22.0 mph.

I agree with you Nick.
14C is a bit high and 1 degree higher than was forecast. My car thermo said 13C
in Exeter after the warm front had gone through. 13 also ties in with my max. of
10.9 here in Haytor.

I've been noticing that Exeter Airport has been reporting high temperatures
for quite a while now, at least since last May.

On some days the anomaly can be as much as 3C (though generally it is
between 1 and 2C higher). It seems that the biggest difference occurs when
the sun is shining.

Night time temperatures can also be quite high but the airport is slightly
more exposed than my station, especially to the south and west so that might
explain this.

Nick,

I must admit it does seem 1c too high this evening.

At 22:00

Teignmouth 12.6c
Holcombe 12.7c http://www.dawlishweather.co.uk/
Exeter 14c http://weather.noaa.gov/weather/current/EGTE.html

Also,

Although this doesn't relate directly to Exeter Airport, I've noticed
that the pressure readings posted in the window of Teignmouth
Meteorological Station are always wrong, by a considerable amount.

The values I post here are my own, and I verify them against Exeter
Airport's pressure readings, and the Met-Office charts posted on
Wetterzentrale.de http://www.wetterzentrale.de/pics/bracka.html

Has anyone else at the Met-Office noticed the error, and informed
Teignmouth Meteorological Station that their instruments need
re-calibrating?
