Pre-race forecast put Singapore GP rain chance at about 10%

RacingNews365’s pre-race weather update, produced in collaboration with WeerOnline, put the chance of rain during Sunday’s Singapore Grand Prix at about 10%, making dry conditions more likely despite the heavy rain that delayed Saturday’s sprint start. The rain began at the Marina Bay Street Circuit about 15 minutes before the start.

The greatest rain risk was forecast for Sunday afternoon and early evening, with the heaviest showers expected to pass before the scheduled 20:00 local start. Rain during the race was not ruled out.

One reader in the comments cited a different Buienradar outlook: rain at 16:00, dry conditions from 17:00 to 19:00, then another chance of rain from 20:00 until at least 23:00. A reply said most major international weather stations forecast dry conditions.

At the time of the update, roughly four and a half hours before the race, RacingNews365’s team on site in Singapore reported no major rain threat. The update also forecast temperatures around 29°C, with high humidity making it feel closer to 35°C.
