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.

Be prepared

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 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.
