Seasonal Temperature Outlook: June-August 2024 (JJA)
Issued: 24 May 2024
For JJA 2024, above-normal temperature is predicted over the ASEAN region.
For JJA 2024, above-normal temperature is predicted over the ASEAN region based on the multi-model ensemble (Figure 4). All three models agree with high confidence on above-normal temperature over most of the region, apart from over the southernmost part of the Maritime Continent where below- to near-normal temperature is predicted by the UK Met Office (Figure 3). Models’ skill for predicting above-normal temperature is relatively good for most of the ASEAN region.
