Wind Rose Diagram — Free Polar Chart Template
This Wind Rose Diagram template plots wind speed and frequency across the 16 compass directions on a polar chart, so prevailing winds jump out at a glance. The sample data spans N through SSE, with the longest spokes at SE (11) and SSE (10) showing winds blowing predominantly from the southeast. It's a ready-made starting point for turning raw direction readings into a clear, presentation-quality wind rose.

Frequently Asked Questions
Can I replace the sample directions and values with my own readings?
Yes. Click "Open in editor" and edit the 16 rows directly, change the N/NNE/NE... labels or values, add or remove rows, and the polar chart redraws instantly. You can also recolor it and export to PNG, SVG, or PDF, all free in your browser with no signup.
Why use a polar chart for wind data instead of a bar or line chart?
A polar (wind rose) chart arranges each compass direction around a circle, so the angle matches the real bearing the wind comes from and the spoke length shows how often or how strongly it blows. That makes prevailing directions obvious in a way a flat bar or line chart cannot.
