Best Places for Vitamin D in Spring, Summer, Autumn and Winter

Seasons here are northern-hemisphere seasons

Seasons are named for the northern hemisphere. The score for a month combines the usable sun window, the minutes needed for a full dose and a comfort factor for heat and rain. Places that would be too hot, too cold or in their rainy or storm season in a month do not count for it. A country is rated at its median coastal place, for skin type III at age 30.
