GREENLAND HEATWAVE FORTHCOMING
The first heatwave is forecast for Greenland around June 1, 2023. Expected temperature could reach +15°C (+59°F) above average in the south low-elevation regions of the ice sheet. We do not yet know if this will mark the expected start of the 2023 Arctic melt season (Danish Meteorological Institute has not called it yet) or if it will possibly be a repeat of the extreme heatwave resulting in record setting glacial ice melt from September 2022 (see our forecast and melt alert). We will continue to monitor the forecasts and the live weather station data from Greenland to see how this event unfolds.
