Monza isn't usually where Formula 1 worries about heat. That's changing this weekend. The FIA has officially declared the Italian Grand Prix a Heat Hazard event, triggering special driver cooling protocols across the entire race weekend.
In a note issued to teams on Thursday morning, FIA Race Director Rui Marques cited Article B1.5.10 of the F1 regulations: forecasts predicting the Heat Index would exceed 31.0°C at some point during Sunday's race were enough to trigger the declaration, made ahead of any cars turning a wheel at the circuit.
Just How Hot It's Actually Going to Be
The numbers behind the declaration are genuinely extreme for early September. Friday's practice sessions are expected to hit around 33-36°C, depending on the specific forecast source, with FP2 alone projected to touch 36°C. Saturday's qualifying session is forecast at 34-35°C, and Sunday's race, starting at 3pm local time, is expected to run in ambient temperatures around 33-34°C.
For context, RacingNews365 notes that typical early-September temperatures at Monza usually sit around 25-27°C — meaning this weekend's forecast runs a full 7-9°C above what's normal for the circuit at this point in the calendar, part of a broader heatwave currently gripping northern Italy.
What the Declaration Actually Changes
Here's what the ruling means in practical terms. Drivers are given the option to wear a specialised cooling vest, a fireproof garment fitted with tubing that circulates chilled liquid — typically glycol — powered by a pump and thermal store built into the car. Any driver who opts against wearing it must instead carry 0.5kg of ballast, a deliberate design choice that prevents skipping the cooling system from becoming a performance advantage.
The FIA had originally hoped to make these vests mandatory, but pulled back after driver pushback over comfort and effectiveness concerns, leaving the choice optional rather than compulsory.
Where This Rule Actually Comes From
The Heat Hazard protocol isn't a new invention — it was introduced specifically in response to the 2023 Qatar Grand Prix, a weekend that left multiple drivers in serious physical distress due to extreme heat and humidity in the cockpit. That race became the catalyst for the FIA to formalise a systematic response rather than handling extreme conditions on an ad-hoc basis.
Since the protocol's introduction, Monza becomes the fourth race to be officially declared a Heat Hazard, following the 2025 Singapore Grand Prix, the 2025 United States Grand Prix, and this year's Austrian Grand Prix earlier in the season.
Why the Timing of the Announcement Matters
The FIA made this declaration before a single car had turned a lap at Monza, rather than reacting once the weekend was already underway. That's a deliberate procedural choice — teams need advance notice to physically fit the cooling equipment and account for the associated weight provisions in their car setup, something that can't realistically be arranged mid-session.
A Genuine Engineering Trade-Off
Monza already presents a delicate compromise for teams: it's a low-downforce circuit built almost entirely around straight-line speed, meaning any additional cooling hardware has to be managed carefully to avoid adding unnecessary drag. Layering heat-hazard cooling equipment on top of that existing balancing act adds another variable teams have to work through during an already technically demanding weekend.
What This Means for the Race Itself
The declaration itself isn't a signal that the race can't proceed — it's explicitly a preventative safety measure, not a prediction of cancellation or disruption. But it does add a genuine layer of physical difficulty for drivers who'll already be pushing hard around one of the calendar's fastest circuits, in cars that trap heat considerably more than a typical road vehicle.
For teams and drivers heading into an already title-relevant stretch of the season — with championship leader Kimi Antonelli facing a grid penalty at Monza and McLaren riding momentum from consecutive wins — extreme heat adds one more variable to a weekend that already carries plenty of storylines on track.
