Figure 1: Rainfall Outlook

Figure 2: Temperature Outlook

 

In the first fortnight of July 2020, wetter conditions are expected over the equatorial regions of Southeast Asia, whereas drier conditions are expected over the northern and central parts of the Philippines.

In the first week of July, wetter conditions are expected over the southern parts of Mainland Southeast Asia.

Warmer conditions are expected over the northern and central parts of the Philippines, and the southern parts of the Maritime Continent for the first fortnight of July. For Mainland Southeast Asia, there is a higher likelihood of warmer conditions in the first week of July.

No discernible Madden-Julian Oscillation (MJO) signal is observed and there is no consistent signal in the models’ predictions for an MJO to develop in the forecast period.

 
The outlook is assessed for the region in general, where conditions are relative to the average conditions for the corresponding time of year. For specific updates on the national scale, the relevant ASEAN National Meteorological and Hydrological Services should be consulted.
