El Niño 2026–27 in Lithuania
Odds favour a wetter-than-normal December–February in Lithuania (57% chance). Past El Niño years show no consistent rainfall pattern here.
Temperatures: likely warmer than the 1993–2016 average (55% chance).
El Niño status: El Niño Advisory (NOAA, 12 November 2026). Outlook: Copernicus, issued November 2026.
Outlook for the next six months
December–February
Rainfall: likely wetter
Temperature: likely warmer
February–April
Rainfall: likely wetter
Temperature: likely warmer
Away from the tropics, seasonal rainfall forecasts have limited skill. Treat small shifts in the odds as weak signals. “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.

Official warnings
Lithuanian Hydrometeorological Service (LHMT)
This is not an official forecast or warning. Seasonal outlooks give odds, not certainties. For warnings and decisions about safety, follow your national weather service.
What you can do
If it turns out wetter
- Find out whether your home, school or workplace is in a flood-risk area, and know your evacuation route.
- Clear gutters and drains before the rainy months.
- Keep important documents, medicines and a torch in a waterproof bag.
- After heavy rain, avoid walking or driving through flood water and follow local advice on drinking water and mosquito-borne disease.
If it turns out hotter
- Check on older relatives, neighbours and anyone who lives alone during hot spells.
- Drink water regularly, and avoid hard outdoor work in the hottest hours.
- Know the signs of heat exhaustion (dizziness, headache, nausea) and when to get medical help.
