About the 16-day forecast
LiveWeather provides up to 16 days of forecast data for St Petersburg — more than most weather apps which are limited to 7–10 days. Data is sourced from Open-Meteo's ensemble models which combine multiple NWP systems including ECMWF for maximum accuracy. Forecasts beyond day 7 should be considered indicative; confidence decreases with time.
Daily high and low temperatures are the maximum and minimum values recorded across the full 24 hours. Precipitation probability shows the chance of any measurable rain or snow occurring during the day. UV Index max is the peak value expected during peak sun hours.
