A weak to moderate pulse of the Madden-Julian Oscillation (MJO) is currently located in the Maritime Continent. In February, the Intertropical Convergence Zone (ITCZ) and the South Pacific Convergence zone were active with the SPCZ shifted south of its normal position over Vanuatu to Fiji.

The Regional Climate Watch is a guidance product designed for heightening National Meteorological and Hydrological Services awareness of an ongoing or high probability foreseen climate anomaly and its potential impacts on communities so that they can take appropriate action. This watch is disseminated to serve as a mechanism for initiating national preparedness activities and/or a series of events that affect decision-making

The 2025–26 La Niña event is weakening and is expected to end soon, as ocean temperatures in the central tropical Pacific have been warmer than the La Niña threshold (−0.80 °C) for the past two weeks. While oceanic indicators of the El Niño–Southern Oscillation (ENSO) are steadily weakening, atmospheric indicators, such as trade winds, pressure and cloud patterns in the tropical Pacific remain consistent with borderline La Niña conditions

This year is shaping up to be a big one for the region and we continue to strengthen our collaboration with our partners to support our Members. With 2025 recorded as one of the warmest years on record, the need for enhanced climate science services and environmental resilience has never been more urgent.

Climate change is not gender neutral. Global evidence confirms that climate change impacts are not experienced equally. Across the Pacific, including in Micronesia, women often carry the greatest burden of climate impacts because of the roles they hold in their families and communities.

The Regional Climate Watch issued by the Climate and Oceans Support Program in the Pacific (COSPPac) replaces the existing Pacific ACCESS-S Update Bulletin.

La Niña continues in the tropical Pacific. The Indian Ocean Dipole (IOD) is expected to remain neutral until at least the end of autumn 2026. The IOD is typically inactive from December to April. The Bureau's model indicates that SSTs in the tropical Pacific are likely to return to a neutral El Niño–Southern Oscillation (ENSO) state in late summer, consistent with most international models. Neutral conditions are favoured through to at least late autumn
