I’ve no idea yet how reliable it is but I do enjoy the idea of dryoutside.

It solves that eternal problem of ‘should I hang my washed clothes outside to dry?’ I mean, who likes hanging stuff out twice because they didn’t dry properly outside within the day?

DryOutside is designed to give a straight answer based on physics, not just weather icons. We help you pick perfect line-drying windows to save energy and protect your clothes.

Factors considered include heat, humidity and wind. There’s also a calculator to simulate how long your preferred type of clothes would take to dry under your chosen weather scenario.

Unfortunately the current result for my location is that in fact no days at all are predicted to be suitable for drying in the next few days :(.
