... If it had occurred mid-afternoon I'd tend to agree with you, but
the sunshine from the 18Z SYNOP (i.e. in the hour 1650-1750Z) was
0.2hr, having been 0.0hr for several hours previously. This is too
brief a period for the temperature to have responded so out of kilter
with other stations in the area: also, as noted above, our site, which
is highly sheltered, is much warmer than Hurn and had the same
sunshine profile (we're only a few miles away).

Only just noticed this discussion but If it helps, albeit from a bit
further away than where you are, the maximum here in Fareham and also
at Solent MRSC down the road was 20.4 deg C in both cases.
