Overview

• Formula 1’s governing body activated a heat alert for Singapore based on forecasts exceeding 31°C with humidity up to roughly 80%, requiring functional in‑car cooling systems under updated rules.
• Drivers may use cooling vests, though they can opt out if they manage the associated weight implications, reflecting tightened measures after the 2023 Qatar heat incidents.
• Heavy showers are predicted through practice and on race day, increasing the likelihood of interruptions on a circuit that already carries a reported 93% Safety Car probability.
• Pirelli selected the C3, C4 and C5 compounds, with teams expecting a one‑stop strategy in baseline conditions unless Safety Car periods or weather force deviations.
• No major performance upgrades were announced, placing emphasis on high‑downforce setups, brake and rear‑tyre management on the bumpy 19‑turn street course, as Red Bull arrives on a two‑race win run and McLaren can clinch the title unless Mercedes gains 31 points more than Norris and Piastri.
