Near my current address in Palo Alto, Calif., BestForecast is Good while the NWS is Fair, which means it is sometimes off by 3.5 degrees Celsius. Near my old house in the Sunset, BestForecast’s recent record is rated “Excellent” (meaning it predicted the high temperature to within 1.5 degrees Celsius) while the NWS is only “Good,” meaning it was up to 1 degree worse. If you scroll down the page on any forecast, the site will tell you how well BestForecast has performed for your area over time, and how well the Weather Service has as well. But Weather Underground is transparent about its performance. “It’s probably 1 or 2 Fahrenheit degrees better overall,” Celenza says when I press him to give me a ballpark figure, but he notes that that’s just an average-in some places BestForecast could be significantly better than the weather service (and, in some places, it could be worse the weather is unpredictable, after all). Because the weather varies so much from place to place, the quality of Weather Underground’s forecasts-and its relative performance compared to NWS-depends on where you’re talking about.
