The 2025 F1 Singapore GP returns under the dramatic glow of Marina Bay’s city lights, and this year the stakes feel higher than ever. But no circuit demands more from drivers than Singapore’s unforgiving mix of heat, humidity, and urban constraints; add in a newly declared “heat hazard” and the tenor of the weekend is set: survival will matter as much as speed.
Weekend Breakdown & Format
The Singapore GP 2025 weekend brings Formula 1 and F1 Academy together under the Marina Bay lights, mixing high-stakes racing with the city’s unique night-time spectacle. Fans can expect relentless action and a timetable that keeps both series in the spotlight.
Singapore GP 2025 Circuit Guide: Marina Bay Street Circuit
It’s a low-speed, high-stress layout: many tight corners, heavy braking zones, and minimal run-off. The challenge is compounded at night, under high humidity and minimal cooling, Singapore is among the most physically punishing races.
This year, the FIA has declared a heat hazard for the first time in F1 history, triggered by forecast ambient temps exceeding 31°C and humidity that will push cockpit “perceived” temps even higher.
Drivers may utilize new cooling vest systems or adjust ballast to offset heat strain, a tactical variable we’ve not seen before.

- F1A – 2:03.631 – Abbi Pulling (Rodin Motorsport) – 2024
Weather Forecast & Session Impact
Friday – October 3
Expect hot, humid conditions with embedded tropical cells: scattered thunderstorms possible, highs around 31°C, feels hotter, with a warm, saturated track surface. Showers are likeliest in the afternoon build-up window.
F1 impact: FP1 (late morning) should run on a dry but greasy track; tyre warm-up is easy, but thermal degradation will spike on longer runs. FP2 sits closer to convective shower risk; any downpour could rubber-strip the surface and reset grip. Engine and brake cooling margins matter, and the newly declared FIA heat hazard elevates driver heat-strain management (pre-cooling, in-lap airflow, cockpit cooling).
F1A impact: Early F1A Practice should benefit from slightly lower core temps; Qualifying near midday risks brief, heavy showers. Expect bigger lap-time swings if a cell clips Marina Bay between banker and push laps.
Saturday – October 4
Forecast trends point to very warm conditions with storms in parts of the city; peak heat around 33°C. Any short, intense shower can produce rapid grip changes as the surface dries under lights.
F1A impact: Race 1 (early morning) should start hot but generally drier; safety-car probability rises if a passing cell leaves damp patches over painted lines and kerbs.
F1 impact: FP3 (late morning) will stress rears under traction; teams will shorten long runs to protect tyres. Qualifying at night reduces track temp but not humidity; if a pop-up shower hits pre-session, expect a treacherous Q1 evolution and high red-flag risk through the heavy-braking zones. Cooling vests and hydration protocols remain a performance variable even after sunset under the heat-hazard designation.
Sunday – October 5
Showers are possible earlier in the day, then trending to a warm, sticky evening near 32°C; residual damp patches can persist in shaded areas.
F1A impact: Race 2 (morning) may dodge the heaviest cells but could see localized spray if a shower clips the bay. Tyre temperature will climb quickly once the track dries.
F1 impact: The night race (local lights out ~20:00) still runs in oppressive humidity; tyre thermal management and driver heat stress are central. A brief pre-race or formation-lap shower would reset rubber and widen strategy deltas; otherwise expect a one-stop bias influenced by safety-car timing rather than raw wear.
Tyre Choices & Strategy Outlook for the Singapore GP 2025
Formula 1 Tyre Strategy
Pirelli returns to Marina Bay with the same trio as last year: C3 as Hard, C4 as Medium, and C5 as Soft. They have deliberately excluded the C6 from use this weekend, citing overheating risks and high thermal stress under Singapore’s humid conditions.
Overheating is expected to be the dominant enemy. Singapore’s humid night airs and the tight street layout generate blistering tyre temperatures. The Hard and Medium compounds will almost certainly form the backbone of race strategies, favored for durability and stability under heat. Softs could still appear early or in a late Safety Car restart, especially if someone gambles on fresh grip to leap positions when the track is rubbered in.
Since overtaking is tough even after recent layout tweaks, any driver able to hop from Soft to Medium/Hards with a tire delta could gain places in pit phases. Managing tyre degradation, preserving camber and carcass integrity, and cooling the rear end will be critical. Anyone overdriving early risks an irreversible fade later.
Given the FIA’s heat hazard declaration, teams must juggle cockpit cooling, tyre pressures, and stint length carefully. A conservative long stint may yield better consistency than chasing outright pace. The key will be reacting swiftly to Safety Cars or track conditions, because in Singapore, small advantages often decide who finishes on the podium.

F1 Academy Tyre Approach
In F1A, tyre choice is simple and singular: one slick compound in dry sessions, and a grooved wet tyre for rain.
There is no hard/medium/soft spectrum, just the one slick for all dry runs.
The slicks must be kept hot immediately, as the peak window is short and strong performance drops if temps decline. In wet or damp conditions, the grooved tyres are essential to channel water and maintain grip. Because the rear tyres are wider, they manage power delivery and reduce wheelspin, while narrower fronts maintain balance under turning loads.
What to watch
Drivers & Storylines to Watch at the Singapore GP 2025
Among the key narratives heading into the Singapore GP 2025 is whether Max Verstappen can sustain his charge against McLaren’s title contenders? It’s a surprising but fair question now. Heading into Singapore, Max Verstappen carries the momentum of back-to-back wins in Monza and Baku that have clawed 35 points off Oscar Piastri’s lead. The gap has shrunk from 104 to 69 with seven rounds to go. While both circuits favored lower downforce, Marina Bay flips the challenge, high downforce, high heat and this will test whether Red Bull’s late upgrades translate to circuits unlike the likes of Baku.
Piastri’s bounce-back under pressure is another storyline. His crash on lap one in Baku ended a 44-race streak of points finishes and handed him his first non-scoring weekend. Singapore demands mental resilience. A strong return there and a clean weekend free of incidents will reaffirm him as a model of consistency. But can he contain the regained charge behind from Verstappen and Lando Norris?
Dark-horses to upset the pecking order bear close watching. Carlos Sainz arrives confident after his Baku podium. Singapore’s tight layout rewards defensive skill and clean execution, attributes he showed early in the season. Liam Lawson and Isack Hadjar from Racing Bulls are another pair to monitor; Singapore often rewards grit over pure pace, and they’ve already shown they can punch above the midfield bar.
Physical and strategic attrition could decide the race. Singapore is as much a mental marathon as a speed test. Hydration, tyre management, and focus under heat might unhinge even frontrunners. And with safety car history on these streets, race control interventions may shake the grid again. So those who stay alert could gain big.
What Happened in 2024
The 2024 Singapore Grand Prix delivered a milestone weekend for McLaren. Lando Norris converted a disrupted but ultimately decisive pole position into a flawless lights-to-flag victory, his sixth career win and McLaren’s first consecutive triumphs since 2012. Teammate Oscar Piastri backed him up with third place, while Max Verstappen split the pair in second, unable to match Norris’ relentless pace under the Marina Bay lights. Uniquely, the race ran without a single Safety Car or yellow flag, the first time in the event’s history.
It was also historic for another reason: Daniel Ricciardo bowed out of Formula 1 after his 257th start, taking fastest lap but finishing 18th, before handing over his seat to Liam Lawson for the U.S. Grand Prix.
F1 Academy 2025: Key Storylines Under the Lights
Title pressure arrives in Singapore with a vengeance. Doriane Pin leads the standings from Maya Weug and Chloe Chambers, and the field knows Marina Bay rewards patience as much as pace. Last year the series made its debut here, with Abbi Pulling setting a 2:03.631 benchmark lap on a layout that punishes every mistake and gives little cooling time on straights.
Track evolution will be dramatic from Friday to Sunday. F1 Academy practices and qualifies on a surface that will ramp up quickly as Formula 1 lays rubber, which can transform braking references and traction. Drivers who nail banker laps early in qualifying will carry control into Race 1, while those who adapt fastest to a grippier night surface can flip the script on Sunday. The official schedule confirms back to back outings across late afternoon and evening slots, which further increases setup compromise between cooler and hotter phases.
Another storyline to follow is Lisa Billard’s debut. At just 16 years old, she enters Singapore as the youngest ever F1 Academy Wild Card driver, representing Gatorade in a special #60 livery. Her appearance under the lights at Marina Bay not only celebrates the brand’s 60th anniversary but also highlights how the Wild Card program continues to bring fresh talent into the series and expand the championship’s competitive depth.
F1 Academy 2024 Recap: Pulling’s Clean Sweep in Singapore
The 2024 F1 Academy weekend in Singapore was all about Abbi Pulling. The Alpine driver produced a flawless double, winning both races from pole and setting fastest laps in each. Her clean sweep marked one of the most dominant displays of the season and tightened her grip on the championship.
Ferrari’s Maya Weug twice finished second, showing strong pace but unable to close the gap, while Mercedes’ Doriane Pin secured back-to-back podiums in third. Williams driver Chloe Chambers also impressed with consistent top-five finishes.
Wild Card entry Ella Lloyd fought hard in the midfield, collecting valuable experience despite penalties. Under the lights at Marina Bay, Pulling’s control stood out, while the rest of the field delivered close battles that highlighted the growing depth of the series. The results confirmed Singapore as a pivotal round in the title fight.
