Starting from November 2019, APCC has changed the official seasonal climate outlook release date from the 25th to the 20th of every month.

The change of the official seasonal climate outlook release is aimed to promote the use and competitiveness of APCC's climate information.

Based on the demand from APEC economies for seasonal outlook at longer lead times, APCC has extended its seasonal outlook service from 3 to 6 months since September 2013. The 6-month seasonal outlook can be applied to various sectors and is very useful for decision-making and supporting policy on disaster preparedness and climate adaptation. The forecasts also have potential for use in estimating agricultural yields and managing water resources.
