Dominant Synoptic Drivers
Dynamic Shear Dynamics
The graph displays projected sea surface temperature trends from June to September 2026 across four major Asian ocean regions: the South China Seas, Bay of Bengal, Guam Expanse, and Indian East Ocean.
Warmer waters can increase evaporation, humidity, monsoon moisture, thunderstorm fuel, and tropical cyclone potential. Cooler waters can suppress convection, reduce local storm energy, and shift rainfall corridors. In summer 2026, the strongest warm signal is shown over the South China Seas, while the Indian East Ocean trends cooler through the season.

South China Seas: warmest SST signal
Bay of Bengal: gradual cooling trend
Guam Expanse: steady warming trend
Indian East Ocean: seasonal cooling trend
