Our weather forecasting system uses multiple high-quality data sources to provide the most accurate predictions possible:

• Open-Meteo API - A scientific weather forecasting service based on the ECMWF and GFS meteorological models

The weather forecasts include comprehensive meteorological parameters:

• Temperature (current, feels-like, and min/max)
• Precipitation probability and amount (mm)
• Wind speed, gusts, and direction (km/h)
• Cloud cover percentage
• Visibility conditions (meters)
• Humidity levels (%)

Our system provides weather forecast data up to 16 days in advance of any F1 session. This timeframe is determined by the limitations of current meteorological models and their accuracy over extended periods.

The availability and precision of weather data follows this schedule:

• 0-3 days before an event: High-precision 15-minute interval data with detailed parameters including temperature, precipitation, wind, humidity, and visibility
• 4-7 days before an event: Hourly forecast data with good reliability for general conditions
• 8-16 days before an event: Daily forecast data showing general weather patterns and trends
• Beyond 16 days: No forecast data available until the event comes within the 16-day window
• Past events: Historical weather data is not displayed for completed sessions

The system uses three types of forecast data, depending on availability:

• 15-minute interval data - The most precise, showing conditions every 15 minutes with detailed parameters
• Hourly data - Used when 15-minute data isn't available, providing hourly snapshots
• Daily data - Used for longer-range forecasts with daily high/low values and general conditions

The "F1 Impact" section provides Formula 1-specific analysis of how weather conditions might affect racing performance, strategy, and safety. This analysis is generated using an algorithm that considers multiple weather parameters and their specific effects on Formula 1 cars.

Our F1 Impact analysis includes assessments of:

• Wind effects - How wind speed and direction might impact aerodynamics, DRS efficiency, and car stability in specific track sections
• Rain implications - Potential for wet conditions, changing grip levels, and tire strategy considerations
• Temperature effects - How ambient and track temperatures might influence tire performance, degradation, and optimal compound selection
• Visibility concerns - Safety implications of reduced visibility and potential for safety car deployments
• Track evolution predictions - How conditions might change during a session, affecting grip levels and strategy timing
• Cooling considerations - Effects on engine and brake cooling requirements
• Humidity effects - Impact on engine performance and driver comfort

The analysis uses specific thresholds developed through historical analysis of weather effects on F1 performance:

• Wind thresholds: Light (<20 km/h), Moderate (20-30 km/h), Strong (30-40 km/h), Extreme (>40 km/h)
• Rain probability thresholds: Slight chance (30-60%), Probable (60-80%), Likely (>80%)
• Temperature ranges: Cold (<15°C), Optimal (15-28°C), Warm (28-35°C), Hot (>35°C)

Formula 1 race weekends include several different session types, each with specific purposes and formats:

Standard Session Types:

• Free Practice 1 (FP1) - 60-minute session where teams test car setups, evaluate parts, and gather data. Rookie drivers sometimes participate.
• Free Practice 2 (FP2) - 60-minute session focusing on long-run pace, tire degradation, and race simulations.
• Free Practice 3 (FP3) - 60-minute final practice session where teams make qualifying preparations and final setup adjustments.
• Qualifying - 60-minute session divided into three segments (Q1, Q2, Q3) that determines the starting grid for the main race. Progressively eliminates slower cars.
• Race - The main Grand Prix event, typically lasting between 1.5-2 hours and covering a distance of approximately 305 km (except Monaco).

Sprint Weekend Format:

• Sprint Qualifying - A shorter qualifying session (45 minutes) that sets the grid for the Sprint Race.
• Sprint Race - A shorter race (approximately 100km, 30 minutes) that awards points to the top finishers and sets the grid for Sunday's main race.

Weekend Format Types:

• Traditional Format - FP1, FP2, FP3, Qualifying, Race
• Sprint Format - FP1, Sprint Qualifying, Sprint Race, Qualifying, Race
