The El Niño continues in the tropical Pacific Ocean. Model forecasts and observations indicate sea surface temperatures in the central tropical Pacific have peaked and are now declining. Sea surface temperatures in the tropical Pacific are expected to return to neutral El Niño–Southern Oscillation (ENSO) levels in the southern hemisphere autumn 2024. Most atmospheric indicators are close to normal levels, although trade winds have temporarily weakened in line with the passage of the Madden-Julian Oscillation through the region.

The El Niño continues in the tropical Pacific. Model forecasts indicate the warmth of sea surface temperatures (SSTs) is likely at or near its peak, with SSTs expected to remain above El Niño thresholds into the southern hemisphere au-tumn 2024. Some atmospheric indicators have weakened over the past three weeks, and the SOI is currently neutral

The El Niño event continues in the tropical Pacific. Sea surface temperatures (SSTs) for December 2023 were higher than average across the central and eastern tropical Pacific Ocean. The extent and magnitude of warm anomalies across the equatorial Pacific has decreased compared with November.

El Niño continues in the tropical Pacific. Higher than average sea surface temperatures (SSTs) in the tropical Pacific persist above El Niño thresholds, with warmer water beneath the surface to support that at the surface. In the atmos-phere, cloud, wind and pressure patterns are consistent with El Niño.

Pacific Sea Surface Temperatures (SSTs) for November 2023 showed a mature El Niño pattern. Across much of the tropical Pacific between 10°S and 10°N, SSTs were more than 0.8°C above the long-term average, increasing to nearly 3°C above average east of the Date Line.

El Niño continues in the tropical Pacific. Higher than average sea surface temperatures (SSTs) in the tropical Pacific persist above El Niño thresholds, with warmer water beneath the surface to support that at the surface. In the atmos-phere, cloud, wind and pressure patterns are consistent with El Niño.

Sea surface temperatures (SSTs) in the tropical Pacific are exceeding El Niño thresholds and have Oceanic indicators firmly exhibit an El Niño state. Central and eastern Pacific sea surface temperatures (SSTs) continue to exceed El Niño thresholds. Models indicate further warming of the central to eastern Pacific is likely.

Oceanic indicators firmly exhibit an El Niño state. Central and eastern Pacific sea surface temperatures (SSTs) con-tinue to exceed El Niño thresholds. Models indicate further warming of the central to eastern Pacific is likely. During September, the trade winds were generally weak across the rest of the equatorial Pacific with some westerlies occurring in the western Pacific.

The Coral bleaching Outlook to 24 September shows patches of area of 'Alert Level 1 and 2' over Kiribati (central Gilbert, northern Phoenix and northern Line Islands).

The Bureau's El Niño Alert continues, with El Niño development considered likely in the coming weeks, despite the current lack of atmospheric response.
