What to know about Monsoon cooling helps Great Barrier Reef coral cover hold steady after bleaching

The Australian Institute of Marine Science (AIMS) reports that coral cover on the Great Barrier Reef remained stable or increased slightly in the 2025-26 season, partly due to monsoon cooling. Despite this initial recovery, researchers warn that the reef remains vulnerable to climate change, frequent bleaching events, and other ecological stressors.

What happened

Monsoon cooling helps Great Barrier Reef coral cover hold steady after bleaching Lisa Lock Scientific Editor Robert Egan Senior Editor A late-summer monsoon in 2026 brought the Great Barrier Reef a reprieve from unfolding coral bleaching, aiding its initial…

Why it matters

Coral cover across all three regions of the Reef increased slightly or remained at similar levels to those recorded last year, indicating limited impacts from 2025's mass bleaching event and the regional bleaching event in the Northern and Central regions…

Common ground

The Reef faced other impacts from flooding and two tropical cyclones, including Narelle, but most of the surveys for this report were completed before its passage as a category 5 system over the Northern region in March.
