Seems to be a consequence of the exposure of the Solent site that
you have
described before - not a misreading of the instruments. NE wind
throughout
of course.

Met Office website 24-hour graph
http://www.metoffice.gov.uk/weather/...er_graphs.html
shows 18°C at 14.00 and 17°C at 13.00, 15.00 and 16.00.

.... Hurn, with essentially the same weather-type yesterday (Tuesday),
managed 15.9°C, from total sunshine 8.5 hours; the sunshine was very
strong for several hours, but enough breeze to stir things up at an
open site to prevent local intense warming.

I don't quote my own temperature readings because they are so out of
kilter with a 'standard' site, but to give you an idea how a *heavily*
sheltered site behaves, our maximum yesterday was 18, some 2degC above
Hurn.

Solent temperature is a 'real' temperature, but it is highly
questionable how 'representative' it is of a broader area.
