Bahrain Grand Prix set for steamy Sepang return with 50% rain threat and track temps nearing 54°C

Formula 1 heads back to one of its most atmospheric – and most punishing – venues this weekend, as the 2026 Bahrain Grand Prix is staged at the Sepang International Circuit in Malaysia, a track the sport has not visited in nine years. And if history is anything to go by, the weather could once again play a decisive role in the outcome.

Malaysia's notoriously unpredictable conditions have shaped plenty of dramatic races in the past. As the forecast notes: "Malaysia's unpredictable weather played a massive role in previous events, with sudden downpours forcing teams to amend their strategies in an instant whilst testing drivers' skills on a slick track."

The outlook for this weekend suggests that drama could repeat itself, with showers a genuine possibility at every stage of the event, while oppressive humidity and high temperatures add yet another layer of complexity for drivers, engineers and strategists alike.

Friday, October 2 – FP1 and FP2

Practice gets underway in hot and humid conditions, with temperatures ranging from 23°C up to a high of 32°C and a heat index that could peak at a stifling 37°C. There is a 50% chance of precipitation, making rain during Friday's running a real possibility. Winds will be light to moderate, averaging 5.4 km/h with gusts reaching up to 21.6 km/h, while track temperatures may soar to 53.85°C – hot enough to significantly impact tyre performance.

Saturday, October 3 – FP3 and Qualifying

The weather for final practice and Qualifying is expected to remain warm and humid, with temperatures between 23.5°C and 31.5°C and a heat index of around 36.07°C amid a punishing 86% humidity. The chance of rain eases slightly to 40%, with winds varying between 4.3 and 10.8 km/h and gusts reaching 27 km/h. Track temperatures could climb to 53.32°C, again posing a serious threat to tyre life.

Sunday, October 4 – Race

Race day looks marginally cooler but no less challenging, with daytime highs of 31°C, a minimum of 23.5°C at night and a heat index that could feel closer to 35°C. The rain risk drops further to 30%, with light winds averaging around 5.4 km/h and occasional gusts up to 21.6 km/h. Track temperatures could still reach up to 46°C, presenting a stern test for both drivers and tyres over the full race distance.

Weekend forecast at a glance

With the forecast pointing to sticky air, searing track surfaces and the ever-present threat of a tropical shower, strategists face a weekend of constant recalibration – and one sudden downpour could be all it takes to scramble the order at a circuit F1 has not contested since 2017.
