I was just checking the August temperature data for local stations and
realised there was (I think) a remarkable event on the 1st. At Solent
MRSC, the minimum was 16.2 and the maximum 17.5. Southampton Airport
recorded either 16 or 17C for all 18 hours of its half-hourly readings
that day. This would be a remarkably flat temperature range for any
month of the year... but in August? It wouldn't have been coastal fog
because the Airport is well inland.

Did anyone else notice this effect last Friday, is it really as
unusual as I think, can anyone "beat" the flatness, and what is the
explanation? (I don't recall that day at all!).

Here are the archived METARS for EGHI, in tabular format:

and hopefully someone who can read them better than me can help!

Cheers
