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: +206ms per °C

Higher temperatures correlate with slower lap times

Confidence: High

Based on 685 clean laps across 15 temperature ranges

Optimal window: 14-18°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.
