16.3 outside, 16.5 downstairs and 21.6 upstairs.
The heating is presently set to 16 and thanks to the high dewpoints outside of late, the dewpoint downstairs is 13C (79% RH) and 13C upstairs too (59% RH). Outside the dewpoint is 12C (77% RH).
It'd be nice to get dewpoints both inside and out in single figures... but without running the heating for a long time, or using the a/c in dehumidify mode, that's not going to happen. And the GFS has double-figure dewpoints here for the next week and a bit!
