El Niño 2026–27 in Myanmar

The forecast leans towards a drier-than-normal December–February in Myanmar (41% chance). Past El Niño years show no consistent rainfall pattern here.

Temperatures: likely warmer than the 1993–2016 average (98% chance).

El Niño status: El Niño Advisory (NOAA, 12 November 2026). Outlook: Copernicus, issued November 2026.

In the tropics, seasonal forecasts generally have useful skill during strong El Niño years, but they give odds, not certainties. “Normal” means the middle third of the model's own 1993–2016 range; because the climate has warmed since then, “warmer” is the usual result almost everywhere.
