Example of weather forecast API usage

| Wind speed | 11.8 mph | 9 mph | 12.4 mph | 16.6 mph | 18.5 mph |
| Wind direction | SW | SW | WSW | WSW | WSW |
| Wind gusts | 24 mph | 23 mph | 27 mph | 28 mph | 30 mph |
| Atmospheric pressure | 30.04 in | 30 in | 30 in | 30 in | 30 in |
| Humidity | 63% | 53% | 40% | 34% | 26% |

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).
