The tropical Pacific Ocean has eased away from the borderline El Niño observed during late 2014. Overall, the tropical Pacific region remains neutral.
Neutral El Niño–Southern Oscillation (ENSO) indicators include central to eastern Pacific sea surface temperatures, temperatures beneath the sea surface and cloudiness near the Date Line. The Southern Oscillation Index (SOI) has returned to near to threshold values, but this is primarily due to tropical weather activity near Tahiti rather than a broadscale climate signal. The SOI is often affected by weather phenomena during this time of the year.
