OR Tambo sits on the Johannesburg Highveld at an elevation of 1,694 metres (5,558 feet) above sea level — among the highest-altitude major airports in the world. This altitude shapes the airport’s weather in distinctive ways: hot, stormy summers and cold, dry, exceptionally sunny winters, with very little of the humidity you’d associate with coastal South African airports.
Johannesburg's Climate at a Glance
Summer (November–March): Daytime highs of 25–28°C, with the Highveld’s famous intense afternoon thunderstorms a near-daily feature, typically building from around 14:00–16:00. These storms are often dramatic but brief, and can cause short delays at OR Tambo — if your flight departs between 14:00 and 18:00 in summer, build in extra time.
Winter (June–August): Dry, sunny and cold. Daytime temperatures are pleasant at 18–21°C in direct sun, but nights and early mornings drop to 2–6°C, occasionally lower. Frost is possible on winter mornings. Winter offers the clearest, calmest flying conditions of the year — minimal rain and excellent visibility — though early departures require warm layers.
Autumn (April–May) and Spring (September–October): Generally the most comfortable seasons for travel, with moderate temperatures and decreasing (autumn) or increasing (spring) rainfall as the seasons transition.
Weather and Flight Delays at OR Tambo
Given OR Tambo’s altitude and the Highveld’s storm patterns, summer afternoon thunderstorms are the most common weather-related disruption — affecting departures and arrivals through reduced visibility, lightning-related ground stops, or knock-on delays from earlier flights. Morning departures are rarely affected. If you’re flying in the 14:00–18:00 window during summer (especially December through February), check your flight status before leaving for the airport.
Winter fog is occasionally a factor in the early morning, though far less disruptive than the summer storm season.
Best Time to Fly Through OR Tambo
For the most reliable flying conditions, May through August offers the clearest skies, least rain and most predictable schedules. If you’re travelling in summer, favour morning departures over afternoon ones to minimise storm-related delay risk.
