Monthly Forecast

The monthly temperature forecast is updated each Thursday and covers the 28 days starting on the following Monday. The forecasted anomaly is produced from the average conditions forecasted over that period by the Global Ensemble Prediction System. A 20 year climatology (1995-2014) of this prediction system obtained from a reforecast is also used in the computation of the forecast anomaly.
