For the first fortnight of August 2019, above-average rainfall is predicted over northern Philippines, Viet Nam, parts of Myanmar and southern Thailand. With the Indian Ocean Dipole (IOD) predicted to remain in its positive phase, the southern ASEAN region and southern parts of the Philippines may experience drier-than-usual conditions.

In terms of temperature, warmer-than-average conditions can be expected over the equatorial ASEAN region and the inland areas of Thailand.

The 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.
