About ZIP-level forecasts

This forecast is computed for the geographic center of the 03801 ZIP code area rather than the city as a whole — in hilly terrain or along the coast, conditions can differ noticeably from one neighborhood to the next. ZIP boundaries and coordinates follow the GeoNames postal database (CC-BY).
