May 2025 Surface Temperature Analysis
In May 2025, surface temperature anomalies across Maritime Southeast Asia showed a mixed pattern. Warmer-than-normal conditions were prominent in Brunei Darussalam, much of Indonesia, coastal Malaysia, and parts of the Philippines and Timor-Leste.
In contrast, cooler-than-average temperatures were observed in mainland Southeast Asia, particularly in Myanmar, Thailand, and Cambodia.
Elsewhere, no other significant temperature anomalies were noted.
