How the swim score works

Water temperature has the greatest weight at up to 55 points. Air temperature contributes up to 25, while light wind and little rain over the past 24 hours add up to 10 each. Missing weather values receive no points and are not estimated.

The score describes comfort, not safety. It does not include local water quality, currents, thunderstorms, swimming restrictions or on-site conditions.
