Crosswind Calculator

Find crosswind and headwind components.

Calculated Output

Crosswind (kts) 10

Headwind (kts) 17.321

Formula: crosswind = wind·sin(angle); headwind = wind·cos(angle)

Step-by-Step Breakdown

1. Values used:

2. Wind speed = 20 kts

3. Angle to bearing = 30 °

5. Crosswind = 10kts

6. Headwind = 17.321kts

Did this calculator solve your problem today?

The math behind it

crosswind = wind speed × sin(angle); headwind = wind speed × cos(angle).

20 kt at 30°→10 kt cross,17.3 kt head.
