Warmest in UK, according to Ceefax p.407, was Bolton at 30C, is that
your
station?

Goodness no, I'm afraid my ramshackle attempt at a temperature shield
would in no way count as a 'station'
However it is always heartening to see my own readings correlating
well with the official ones, especially the extreme ones.

Readings from Bolton have in the past year or so been reported on
the weather in the local news. I haven't noticed this before, it must be
a new site, and I am wondering as to it's location.....

It's part of a secondary network of AWSs called the CDL
(Campbell Data Logger) network run by the Met Office to
which I do not have access. If I remember rightly, and
I'm happy to be corrected, the Bolton site is on the southern
fringe of the town (Great Lever? Lever Edge?) and may
well be at a municipal depot. On that basis it may well be
above concrete or asphalt rather than grass. It may also be
that the temperature sensor is in one of those micro-screens
which over-read in comparison with a normal screen by
2-3 degC in calm sunny weather. I am told it recorded
30.6°C on Monday,

From the hourly data or a maximum ? Either way, if this data was being
ingested into Ceefax, and I would be quite surprised to find that it was,
then I would expect it to show 31C and not 30C (assuming a max before 18Z).
