Drying Days

It reached 95° F today with 26% relative humidity. These are good drying days. But if you are neither a) drying your clothes on a line outside or b) a watercolorist this may be an unfamiliar concept. How rapidly do wet materials dry given the present combination of relative humidity and wind speed? It doesn’t seem to feature in weather websites in the United States, though I did a Kagi search on “drying days” and came up with a laundry drying guide for London. Today’s weather there was rated “Superb”.

I am now trying sketching experiments with layers where I am painting first with loose watercolors, and then drawing over the watercolor with my Derwent drawing pencils. This calls for good drying days, since the paper needs to be perfectly dry before drawing on it. Here is a sketch I did earlier today in this manner of our laundry on the drying rack.
