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. This place is smaller than one forecast grid cell, so the nearest cell is used.

Be prepared

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.
