Looks like there might be something not quite right with your RH sensor,
Alan. A temperature of 22.2 with a RH of 82% gives a dew-point of about
19C which is way too high. The airmass dew-point looks to be around
14-15C. I've thought for a while that your RH values looked on the high
side.

Does that mean mine is correspondingly too low at the moment? I'm
currently showing 21.6C and RH 50%, DP 10C.
