Round 20 of the 2026 season brings the Formula 1 paddock to the Autodromo Jose Carlos Pace, universally known as Interlagos, for the final leg of this demanding triple header. Brazil has delivered some of the greatest wet weather classics in the history of the sport, and this weekend's meteorological outlook suggests we could be in for another dramatic chapter.
Looking back at last year, the grand prix ran in the dry with Lando Norris taking victory for McLaren. He led home a chaotic Sunday afternoon featuring multiple Safety Cars and crashes, beating Kimi Antonelli and Max Verstappen to the flag. Norris arrives ready to fight at the front once again, while Antonelli and Verstappen are locked in the spotlight alongside the Ferraris—with all eyes on Antonelli to see how he performs after recently sealing his maiden Drivers' title.
Friday, November 06 kicks off the action with FP1 and FP2 under cloudy and mostly dry skies. Temperatures are projected to reach a high of 25.5°C alongside a low of 18°C, though morning fog could roll in if there is heavy rain the day prior. Gentle winds averaging 9 km/h with gusts up to 30 km/h will accompany a 30% chance of precipitation early in the morning and again at night. Expect track temperatures to hit roughly 45°C during the afternoon sunshine, making for generally favourable conditions punctuated by the threat of an isolated shower. The maximum temperature is expected to reach 25 Celsius with a minimum of 18 Celsius.
Saturday, November 07 brings FP3 and qualifying with a warmer, partly cloudy atmosphere, though the stakes rise significantly. Temperatures will shift between 15°C and 27.5°C, with the maximum temperature expected to peak at 27 Celsius and the minimum dropping to 15 Celsius. Light to moderate winds could reach 25 km/h, alongside non-thunderstorm gusts pushing up to 50 km/h. Crucially, the chance of rain jumps to 50%, and any storms that form could drop heavy precipitation from 1400 onwards into the evening. That brings a very real possibility of localised urban flooding and standing water at the circuit, while track temperatures should peak near 40°C depending on afternoon cloud cover.
Sunday, November 08 delivers race day under much cooler and unsettled skies. Temperatures are forecast to plummet to a range of 13°C to 19°C, featuring a maximum temperature of 19 Celsius and a minimum of 13 Celsius. There is a 40% chance of heavy rain and thunderstorms hanging over the grand prix. Moderate winds averaging 15 km/h with gusts up to 40 km/h will sweep the venue, while heavy cloud cover keeps the track temperature capped near 30°C. With a post-frontal air mass locking in cooler conditions, teams will have zero heat hazard concerns to worry about as they tackle what promises to be a wild Sunday afternoon.
