Marine Heatwaves and the June 2025 Northern Hemisphere Climate

Neutral or weak ENSO events do not imply low skill climate forecasts. Recognizing the new mid-latitude (mostly warm) SSTA regimes can not only foreshadow climate patterns ahead but also recognize the potential for extreme events such as heatwaves, droughts, and flooding rainfall episodes.

Australia Week 2-4 Outlook: Comparing ECM and AI Temperature Forecasts

An interesting comparison between ECM "weeklies" and the AI GFS ENS 2-4-week temperature anomaly forecast for Australia whereas there is agreement on the upper air pattern (which supports increasing risk of cold in July) and AI GFS ENS offers the cold while ECM "weeklies" doubts the cold risk.

Strong -GLAAM Stalls Weather Patterns, Continues in July

Global atmospheric angular momentum (GLAAM) is currently sharply negative. Negative GLAAM patterns are frequently represented by a slower jet stream, tendency for semi-permanent trough and ridge patterns (caused by the slow down), and responsible for persistent and sometimes harsh weather patterns. The 15-day forecast by all operational models indicates -GLAAM eases but does not end while the CFS V2 6-week forecast carries -GLAAM through July.

Deep Tropics Not Likely to Activate Until Around August 1st

ECMM "weeklies" maintain a much drier than normal precipitation regime across the deep tropics through late July. Implied is lack of any tropical cyclone activity through July emerging in the tropical North Atlantic basin. Areas to watch for possible development is the northern Gulf of Mexico and Bahamas. However, there is the possibility that tropical cyclone season may wait until August 1st for onset.
