Crosswind Calculator

Crosswind Calculator | Aviation & Driving Wind Component Tool

Use our advanced crosswind calculator to compute headwind and crosswind components for any activity.

0–150 (knots, mph, km/h, m/s)
0° = North, 90° = East

Quick reference for using the crosswind calculator.

Headwind

Wind from front – slows you down.

Crosswind

Side wind – pushes you off course.

Tailwind

Wind from behind – increases ground speed.

Crosswind = Wind × sin(θ) | Headwind = Wind × cos(θ)

Crosswind Calculator: Accurate Wind Component Tool

The most trusted crosswind calculator for pilots, drivers, and wind engineers worldwide.

"Precision in every knot." — Aviation Safety Standard

How the Crosswind Calculator Works

  • Angle difference: |Wind Direction − Runway Heading|
  • Crosswind: Wind Speed × sin(θ)
  • Headwind/Tailwind: Wind Speed × cos(θ)
  • Gusts: Added to base wind for worst-case
  • Aviation 6/10 rule: Max demonstrated = 0.6 × (wind+gust)

Understanding Crosswind Calculator Results

  • Crosswind component
  • Headwind or tailwind
  • Relative wind angle
  • Safety warnings (aviation/driving)

Why Use This Crosswind Calculator?

  • All units: knots, mph, km/h, m/s
  • Aviation 6/10 rule compliance
  • Gust modeling
  • Real-time validation
  • Mobile-optimized

Real Crosswind Calculator Examples

  • Runway 18, Wind 270°@20 kt → 20 kt crosswind, 0 headwind
  • Runway 09, Wind 360°@15 kt → 14 kt headwind, 5 kt crosswind
  • Driving East, Wind NW@30 mph → 21 mph crosswind, 21 mph headwind
