The strongest marine heat waves (MHW) on record in the West Pacific and in-between Japan and the Asia Coast extending to MHW’s NEP25A and NEP25B in the Northeast Pacific are well-correlated to the summer 2025 upper air pattern featuring a strong upper-level high-pressure ridge. Similarly, the MHW’s in the east/northeast portion of the North Atlantic are well-correlated to a semi-permanent upper-level high-pressure ridge dominating the west/south portion of Europe during summer 2025.

Strong Negative Indian Ocean Dipole Arrives; La Nina Approaching!
During the past week, the Nino SSTA regions have cooled dramatically. The Nino34 SSTA is -0.49C today, very close to the -0.50C La Nina threshold. Off the northwest coast of South America, the Nino12C chilled rapidly to -0.80C. In the tropical Indian Ocean, the western areas have cooled while the southeast tropics have warmed dramatically signaling a moderate-to-strong negative Indian Ocean dipole (-IOD).
