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: +203ms per °C

Higher temperatures correlate with slower lap times

Confidence: Medium

Based on 657 clean laps across 15 temperature ranges

Optimal window: 22-24°C(bins within 0.5% of fastest median)

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.
