In terms of total monthly precipitation, says an IPMA report, "there is no significant sign in the monthly anomaly of precipitation over mainland Portugal, Madeira and the Azores throughout the period covered by the forecast".

As regards the monthly average air temperature, "a positive anomaly is expected over the entire territory of mainland Portugal and islands for the 3 months covered by the forecast".

That is, the temperature is expected to be warmer than the reference value.

On mainland Portugal, the predicted anomaly is 1.0 to 1.5°C, in the months of August and September, decreasing to 0.5 to 1.0°C in October - with the exception of the central coast, which maintains the anomaly of the previous months.

Over the Madeira archipelago, the anomaly decreases from 1.5 to 2.0°C in August to 1.0 to 1.5 in September and October.

Finally, for the Azores, an anomaly of 0.5 to 1.0°C is expected in the three months covered by the forecast, with the exception of the Eastern Group, for which the anomaly forecast in August is 1.0 to 1.5°C.

It should be noted that the seasonal forecast bulletin is based, as of October 2019 and replacing the EUROSIP forecast system, on the multi-model forecasts provided by the Copernicus Climate Change Service (C3S).
