How WeatherVerity calculates this
Warmer/colder compares mean temperature. Drier/wetter compares maximum precipitation probability, not rainfall amounts. Less/more wind compares mean wind speed. Clearer weather uses the share of clear daylight weather codes, then lower precipitation risk. All places use the same period.
The general Outdoor Score combines precipitation (40%), temperature (30%) and wind (30%). Daylight hours have double weight. Hazardous model conditions score zero for that hour. Every hour must be complete. Ties share a rank.
Forecast intervals must cover the entire comparison period. When source hours cross its boundaries, only the overlapping duration counts, with double weight for daylight. The original hourly scores and endpoint estimates are retained; no new weather values are interpolated. Boundary estimates may therefore include an endpoint just outside the period. The highest and lowest scored intervals can be shorter than one hour at a boundary.
All places use the same UTC period. Earlier hours are forecasts, not observed history. City pages use local time.
