El Niño and La Niña
Latest status (April 2026)
In the past month or so, the sea surface temperatures of the central and eastern equatorial Pacific rose and remained near normal on the whole. Based on the latest oceanic observations as well as forecasts by a number of climate models around the world, the sea surface temperatures of the region are expected to be normal to above normal for the rest of spring 2026. With the continued warming trend in the region through autumn 2026, the situation is expected to develop into an El Niño event in the second half of this year.
