How these suggestions work
Cool, calm and dry. We compare feels-like temperature, hourly precipitation chance and wind using the forecast. Every hour of an outing must meet the activity's minimum score; the highest average fit comes first. Suggestions start on the next available whole hour.
Garden work, laundry and golden-hour photos need daylight; stargazing needs darkness. Photos also need a forecast hour near sunrise or sunset. Weather can change. Check the latest forecast and official warnings before going out.
