Frequently Asked Questions

Our forecasts are based on the NOAA GFS model, one of the most respected weather prediction systems worldwide. For the first 1-3 days, accuracy is typically 85-90%. Accuracy gradually decreases for longer-range forecasts (7-16 days) as weather prediction becomes inherently more uncertain over time. We recommend checking forecasts daily for the most up-to-date predictions.

Our weather data is updated every 6 hours, synchronized with the NOAA GFS model runs at 00:00, 06:00, 12:00, and 18:00 UTC. This ensures you always have access to the latest forecast information available.

The "Feels like" temperature (also known as apparent temperature) represents how the temperature actually feels to the human body. It takes into account factors like humidity and wind speed. On hot humid days, it may feel warmer than the actual temperature, while on cold windy days, it may feel colder due to wind chill effect.
