Seasonal Climate Watch - October 2020 to February 2021

The following text is an extract from the latest report from South African Weather Service:
Date issued: September 25, 2020

Overview

"The El Niño-Southern Oscillation (ENSO) is currently in a weak La Niña state and the forecast indicates that it will most likely remain and strengthen towards a moderate La Niña state during early- and midsummer. With this strong likelihood of a moderate La Niña, there are increased chances of above-normal rainfall in the summer rainfall areas during the coming summer season.

The multi-model rainfall forecast for late spring (Oct-Nov-Dec), however, indicates that the eastern parts of the summer rainfall season may start off with below-normal rainfall, with above-normal expected for the rest of the region. During early- and mid-summer (Nov-Dec-Jan; Dec-Jan-Feb) most of the summer rainfall regions are expected to receive above-normal rainfall, with some parts of KwaZulu-Natal very uncertain and even showing signs of below-normal rainfall.

In general, most of the country is expected to experience above-normal temperatures during late spring, however significant areas over the central parts of the country are expected to have below normal maximum temperatures during early- and mid-summer.

The South African Weather Service will continue to monitor and provide updates on any future assessments that may provide more clarity on the current expectations for the coming seasons."
