Humidity 0%

When I look at the Hourly list I see humidity at between 76% and 84% and on the daily tab using ‘more’ it states dewpoint will be be around 48% with an average humidity of 0% although on some comments it jumps to 10% these look very low and and the hourly seems to be accurate

Which weather station are you using?

it is Rayleigh, GB (Ely Way)

I included a fix to resolve this issue in this Weather Watcher build. You can install it over top of your current version of Weather Watcher.
