Statistical forecasts for European summers (for the months of July and August) are made from the preceding January to February North Atlantic sea-surface temperature (SST) anomaly and issued in March. The forecasts are later updated in July using the March to June SST anomaly.

• Rationale
• Performance of forecasts from January to February SST anomaly
• Performance of updated forecasts from March to June SST anomaly
  
  

• Statistical forecast from January to June SST anomaly
• Statistical forecast from January to February SST anomaly and verification of 2004 forecasts

• Updated statistical forecast from January-June SST anomaly
• Statistical forecast from January to February SST anomaly and verification of 2003 forecasts

• Updated statistical forecast from January-June SST anomaly
• Statistical forecast from January to February SST anomaly and verification of 2002 forecasts

• Updated statistical forecast for summer 2002 from March to June SST anomaly
• Statistical forecast for summer 2002 from January to February SST anomaly and verification of 2001 forecast

• Updated statistical forecast for summer 2001 from January to June SST anomaly
• Statistical forecast from for summer 2001 from January to February SST anomaly

• Updated statistical forecast for summer 2000 from January to June SST anomaly
• Statistical forecast from for summer 2000 from January to February SST anomaly

• Updated statistical forecast for summer 1999 from January to June SST anomaly
• Statistical forecast from for summer 1999 from January to February SST anomaly

• Verification of forecasts issued from 1996 and 1999
