Seasonal Temperature Outlook: June-August 2019 (JJA)
Issued: 30 May 2019
For JJA 2019, above-normal temperature is favoured over most parts of Southeast Asia.
For JJA 2019, all three models – NCEP CFSv2, ECMWF, and UK Met Office (Figures 1-3) favour above-normal temperature over most parts of the region except south of the equator, where near-to-above normal temperature is predicted.
The models’ skill for temperature prediction is generally good for the JJA season for the above normal tercile.

The qualitative outlook is assessed for the region in general. For specific updates on the national scale, the relevant ASEAN National Meteorological and Hydrological Services should be consulted.
