The forecast for the upcoming austral summer suggests that ENSO-neutral conditions are the most probable outcome, though some international models suggest a weak La Niña event. Looking at the rainfall outlook, spring is expected to bring above-normal rainfall to the southwestern Cape and parts of Namibia, while the eastern and northern regions will likely be drier than usual. As we move into summer, the chances of above-normal rainfall increase for most of the summer rainfall region, particularly toward early and mid-summer. As for temperatures, the southwestern Cape will likely see below-normal maximum temperatures in late winter. Initially, the broader region is predicted to have above-normal maximum temperatures, but this will likely shift to below-normal by mid-summer in anticipation of a wetter season. The one exception is the southern coastal areas, where temperatures are more likely to remain above average.
