that's quite a contrast in temperature.

The St James Park maximum temperature on Friday was only 10.1C. The
apparent maximum of 15.0C arises because that was the temperature at
1800 GMT on Thursday evening following the warmth earlier that
afternoon.

Thanks. Presumably the High Wycombe maximum is since 9am only, as I
imagine that it would have been warmer than 7.4C at 6pm the previous
evening.

Dick, I realise that if a 24 hour period is used to define Tmax then some
unexpected figures can emerge, but are you sure that the 15C figure is not a
misprint? I thought that the "day" defining the Tmax figures in the Colin's
tinyurl reference to the Met Office website is the period 0900-2100hrs.
(and a Tmax of 10C is quoted for St James Park)

Please let me know if it is not so simple!

I have always assumed that the maximum temperatures that Colin lists
are for the 24 hours ending at 1800 GMT. On this basis the St James
Park figure of 15.0C is correct, but by the same reasoning the High
Wycombe value is wrong. It should be 9.0C and not the quoted 7.4C. The
value of 7.4C looks to be either the 2100-2100 or 0900-2100 GMT
maximum.

.... just to answer John's query, from the SYNOP reports, the highest
hourly in the period 15/1800 to 16/1800Z was 9.0°C at 15/18Z. I don't
know how WeatherOnline sort their maxima out so can't comment on that
aspect.

As a general remark (not for Dick, because I know he knows!), 'High
Wycombe' is not really a very 'representative' name for the observing
location. It is station number 03660, which unless it's been
significantly moved since my time, is sitting on top of the bunker at
the facility which has as it's nearest village Walter's Ash. This is
some 7 km/4 miles NNW of the centre of High Wycombe, and the observing
point is listed as 204 m amsl, c.f., a figure of around 100-120 m for
the middle of High Wycombe (and 5 m for St. James' Park).

Yes - sorry about that. Max. temps I list are those reported at 18.00 GMT
for the previous 12 hours. If I had checked the map, I would have noticed
that all other stations in the SE were well below 15°C.

It is the max. temp. reported in the 18.00 synop for the 12 hours ending
18.00.

Most of the temperature figures I quote come from the 06.00 and 18.00 synops
and cover periods of 12 hours ending at the synop times:

Min. temps: 18.00 on the previous day to 06.00 on the day in question.
Max. temps: 06.00 to 18.00 on the day in question.

Rainfall totals are for the 24 hours from 18.00 on the previous day to 18.00
on the day in question (the two 12-hour synop totals added together).

I also look at the lists on OGIMET, which show the 06.00 min. temps and
18.00 max. temps, for Charlwood, Exeter, Mona, Leek, Albemarle, Woodford and
St James's Park.

Those figures refer to the previous 24 hours, so I try to exclude any values
which fall outside the synop 12-hour periods.

In this case, I overlooked the fact that the 15.0°C at St James's Park was
recorded the previous day - as Dick Lovett has pointed out.
