Don’t forget your umbrella… La Niña may bring a longer wet season to Timor-Leste

The global weather pattern called La Nina is affecting weather in Timor-Leste and is likely to for the next few months. Although the La Niña is fairly weak, it feels like this wet season has had more rainfall than the past few years.

La Niña is the opposite to the El Niño that brings below average rainfall to much of Timor. In  La Niña years there is more rain, like 20% more rain overall.  The impact is great at higher elevations (above 500m) and in April, May and June. This means a much longer wet seasons in La Niña years, compared to normal years.

There are many benefits of an extended wet season. This includes increased recharge of surface and underground rivers, a longer season for perennial crops to grow and allows for a longer irrigation season on the systems that rely on river flows.
