Eastern Cape
Gqeberha will enjoy clear skies with temperatures ranging from 12°C to 17°C. Westerly winds at 17 km/h will keep conditions brisk along the coast. Humidity levels are high at 72%, but the clear conditions provide good visibility. The absence of cloud cover means cooler overnight temperatures are likely, so evening layers are recommended.
Limpopo
Polokwane will see clear skies and the second-highest maximum temperature of 24°C, with overnight lows around 12°C. Southerly winds at 16 km/h will be noticeable but not disruptive. The clear conditions and low humidity of 16% make this one of the more comfortable regions today. Residents can expect full sunshine and dry conditions throughout the day.

The temperature range means cold mornings will give way to pleasant midday conditions. Cloud cover may reduce direct sunlight intermittently, but no precipitation is expected.
