AccuWeather’s latest projections indicate that hot and humid conditions will persist across Newcastle, Ladysmith, and Vryheid over the coming days. At the same time, however, the forecast includes periods of rainfall and thunderstorms in all three towns.
In this way, the expected showers and storms are likely to bring at least some welcome, if temporary, relief from the ongoing heat.
With this mind, here is a clear and detailed look at AccuWeather’s forecast for the weekend.

Vryheid: Expect a cloudy day that feels comparatively cooler than recent trends. Highs are predicted to reach 29°C, together with some rainfall at various points. In addition, nighttime temperatures will fall to 16°C. Further rain is likely to continue across the town during the night.
