Most of South Africa is likely to experience above-normal rainfall during the upcoming summer season. But much of the Western Cape will be hot and dry, as forecast by Saws in its latest Seasonal Climate Watch report published on Friday.
The report forecasts rainfall and minimum and maximum temperatures from October 2021 to February 2022 based on three probabilistic categories- namely above-normal, near-normal, and below-normal.
South Africa is expected to receive above-normal rainfall throughout the summer period, however this increased rainfall will not extend to much of the Western Cape, which has traditionally dry summer seasons.
The Western Cape is forecast to receive above-normal rainfall in December and January, however the increase in precipitation does not extend to the coastal areas.
This is expected to become more limited by February, with areas in the Cederberg and Witzenberg likely to record below-normal rainfall.
Above-normal temperatures for the Western Cape
South Africa’s summer season is also expected to be hotter than normal across all provinces.
This forecast of above-normal temperatures is especially true for the Western Cape with all areas of the province likely to experience a season which is hotter than normal, especially between November and February.
“The predicted above-normal temperatures are likely to induce exposure to ultraviolet (UV) radiation and heat stress conditions, leading to diseases associated with overexposure to UV and high temperatures,” Saws said in its latest Seasonal Climate Watch report.
“Consequently, the relevant decision-makers are urged to advise the public to take appropriate protective measures.”
