Odds of each outcome compared with the 1993–2016 average.
December–February
February–April
In the tropics, seasonal forecasts generally have useful skill during strong El Niño years, but they give odds, not certainties. “Normal” is 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.

What you can do
If it turns out drier
- Follow water-use notices from your local water utility, and fix leaks early.
- Farmers: check planting advice and drought bulletins from the national agriculture and weather services before the season.
- Clear dry vegetation near homes where wildfires are possible, and know your local fire-danger rating.
- Keep a few days of drinking water stored if supply cuts have happened in past dry years.
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.
