Wind Adjustment Calculator

Convert wind-aided or wind-affected sprint times to equivalent still-air performances. Essential for comparing 100m and 200m performances run under different wind conditions, using a peer-reviewed statistical wind model (Moinat et al. 2018).

Race Distance

Race Time (seconds)

Wind Speed (m/s)Positive = tailwind, Negative = headwind

t₀ = t + c₀·w + c₁·w·t + c₂·w²

(Moinat et al. 2018 data-driven model, 100m coefficients: c₀= -0.0449, c₁= 0.009459, c₂= -0.0042 — a +2.0 m/s tailwind is worth ≈0.12s)

Enter a time and the wind reading from the meet to get the still-air equivalent. Or start from an example:

How coaches use the wind adjustment calculator

Use this wind calculator when you need to compare 100m or 200m times run in different wind conditions, or judge how much a reading on the gauge really helped or hurt.

Convert a wind-aided 100m or 200m time to its still-air equivalent.
Compare two athletes whose marks came with very different wind readings.
Judge whether a breakthrough PR was fitness or a +1.8 m/s gift.
