Method note: temperature is adjusted to summit elevation by MET Norway; wind and rain come from the global model grid, so real wind on an exposed summit can be stronger. Gust data is not available from the global model for Indonesia. Sunrise/sunset times are calculated for the standard horizon. Full details on data & methods.

Important: the forecasts on this site are automatically processed numerical model output (MET Norway), not official BMKG warnings and not volcano status.
