Track Temperature Evolution

Temperature vs Lap Time

Lap times grouped by track temperature bins. Shows how temperature affects pace.

How Temperature Affects Pace

Estimated effect: +9ms per °C

Higher temperatures correlate with slower lap times

Confidence: Low

Based on 5059 clean laps across 20 temperature ranges

Low reliability. This estimate does not account for driver changes, class differences (ZP2/ZR2/ZR3 have different baseline pace), or tire degradation over stints. Temperature explains very little of the lap time variation. Refer to the chart above for the actual relationship between track temp and typical lap time.
Optimal window: 74-110°C(bins within 0.5% of fastest median)

Wind Impact on Sector Times

Scatter plot showing wind speed vs sector times across all laps

Methodology

  • Each lap is correlated with the nearest weather reading (recorded every ~60 seconds)
  • Pace impact estimated by comparing typical lap times across 2°C temperature ranges
  • Condition score (0-100) considers track temp deviation from optimal, humidity, wind, and rain
  • Optimal windows use 15-minute rolling analysis to find periods with most top-10% laps
  • Note: With data from a single race, reliability is limited. Use these estimates as directional guidance rather than precise values.
