Oscar Piastri is preparing for significant uncertainty ahead of the 2026 Miami Grand Prix, with heavy rain forecast set to potentially disrupt the race. The McLaren driver highlighted that wet conditions could introduce variables that teams have yet to fully understand this season.
Piastri is set to start from seventh on the grid following a difficult qualifying session. However, with all races so far held in dry conditions, the performance of the current generation cars on a fully wet track remains largely unknown, particularly in terms of aerodynamic response and tyre behaviour.
"I think probably build some oars," he said, referencing the potential severity of the expected weather conditions.

From a technical perspective, the primary challenge extends beyond mechanical grip to the behaviour of the power unit, particularly how energy delivery is managed electronically. In wet conditions, throttle modulation and torque application become critical due to the significantly reduced margin for error.
Piastri pointed out that the key uncertainty lies in how these systems will interact with a low-grip surface, especially during traction phases on corner exit.
"No one really knows how these cars will behave in the rain. It depends on how the power is delivered and controlled."
Although Pirelli has conducted wet tyre testing earlier in the year, not all teams have comparable data, potentially creating performance gaps depending on preparation and understanding.
Piastri also noted that while the fundamental driving characteristics may not differ dramatically, the risk factor increases considerably. Small mistakes in braking or acceleration can have amplified consequences in wet conditions.
"The margin for error in the wet is significantly lower. We need everything to behave as expected."
With unpredictable weather looming, the Miami Grand Prix is set to become a test of adaptability across the grid. Strategy, vehicle control, and system management will play decisive roles in determining the outcome under potentially extreme conditions.
