The 2026 Singapore Grand Prix is the next race on the Formula 1 calendar, taking place at the iconic Marina Bay street circuit this weekend.
Track action begins on Friday, October 9, with Free Practice 1 and Sprint Qualifying, before the main race takes place on Sunday, October 11.
The FIA has already issued an official heat hazard warning ahead of the weekend, with sweltering temperatures expected across all three days of competition.
Friday is forecast to see temperatures peak at 34 degrees Celsius, but the humidity will make conditions feel as brutal as 41 degrees on the ground.
Weather services are advising caution for anyone doing strenuous activities outside, which paints a vivid picture of just how gruelling conditions will be for drivers.
Thunderstorms are forecast for Friday morning with thundery showers in the afternoon, though the late-afternoon start of track sessions may help avoid the worst of the precipitation.
Saturday’s Sprint race at 5pm local time and Qualifying at 9pm face a similarly tricky forecast, with spotty thunderstorms expected in the afternoon and rain possible into the evening hours.
The Saturday Qualifying session for the Singapore Grand Prix could be particularly affected, with evening rain threatening to disrupt what is always one of the most dramatic sessions of the year.
Sunday’s race, with lights out scheduled for 8pm local time, carries an 85 percent chance of precipitation, meaning wet conditions could define the outcome of the grand prix.
Peak temperatures on race day are forecast at 32 degrees Celsius, still above the FIA’s official threshold for declaring a heat hazard warning.
Adding a further complication to an already difficult weekend, Singapore is currently experiencing what authorities have described as very unhealthy air quality levels.
The poor air quality has been caused by fires in Indonesia, with natural winds dragging a smoke haze across into Singapore, creating an additional challenge for everyone trackside.
This is a new headache layered on top of the usual Singapore heat, making this one of the most demanding weekends of the entire 2026 Formula 1 season for drivers and teams alike.
