How the Golf Weather Index works

Every hour is scored 0–100 by blending eight weather factors that actually affect a round of golf, with air quality shown alongside as an advisory. Higher is better.

🌡️

Temperature

Ideal 65–78°F. Cold below 45°F and heat above 90°F drop the score fast.

💨

Wind Speed

Calm is best. Big penalty above 15 mph, brutal above 25 — irons get sketchy.

🧭

Wind Direction

Shown as compass + arrow so you can plan holes into and downwind.

💧

Dew Point

Above 65°F feels muggy; above 72°F is oppressive. Ball flight and grip suffer.

🌫️

Humidity

Mild penalty above 70% — makes heat feel worse and softens greens.

🌧️

Precipitation

Chance and intensity of rain. Heavy penalty — nobody wants a soaked scorecard.

☁️

Cloud Cover

A little cloud cover is ideal — full overcast dims the day slightly.

☀️

UV Index

Advisory factor. Extreme UV nudges the score down and reminds you to reapply.

🍃

Air Quality

US AQI shown for context. Above 100 is Moderate; above 150 is Unhealthy for Sensitive Groups. Consider a mask or shorter round when smoky.

The GWI scale

85–100 Prime golf weather — book it.
70–84 Great day for a round.
55–69 Playable, minor annoyances.
40–54 Tough but doable — dress for it.
20–39 Rough — casual round only.
0–19 Stay home. Practice indoors.

FAQ

Where does the weather data come from?

Open-Meteo, a free, high-quality forecast API that aggregates the world's leading weather models. No sign-up required.

Is the score personalized?

Not yet — GWI uses a fixed formula tuned for a typical amateur golfer. A future version could weight things differently for junior/senior play, walkers vs. carts, and preferred temperatures.

Can I check tomorrow?

Yes. The hourly strip shows the next 36 hours so you can see today and tomorrow at a glance. The "Best windows" section highlights the top three hours.

Does it know real course conditions?

No — GWI is a weather score, not a course-conditions report. Frost delays, cart-path-only rules, and course closures still require a call to the pro shop.
