Monthly Temperature Outlook – June 2025
Issued: 23 May 2025
For June 2025, above-normal temperature is predicted over Southeast Asia.
For June 2025, above-normal temperature is predicted over Southeast Asia, based on the multi-model ensemble ( Figure 1). While over the Maritime Continent the models show high likelihood (>70% chance) of above-normal temperature, they are slightly less confident on above normal temperature over Mainland Southeast Asia, with 60-70% chance for much of the region. Most models predict above-normal temperature as the most likely tercile (at least six of the models, Figure 2). Model skill for predicting above-normal temperature is good for most of Southeast Asia.

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.
