Best-in-class accuracy
Our data are approximately 5% more accurate for a 2-day forecast and 12% more accurate for a 7-day forecast. Forecast accuracy is based on temperature, clouds, and precipitation forecasts errors. A higher percentage means better forecast accuracy (100% -forecast without error- is unachievable).
