Weather shapes every round of golf. Wind changes club selection, rain softens courses, heat drains energy and lightning is a serious danger. Modern forecasts and radar apps give golfers far more information than ever, if you know how to read it. Here's how to use weather forecasts to plan tee times, pack the right gear and make smarter decisions on the course.
Wind
- Average wind vs gusts: a forecast of 12 mph gusting 25 mph is very different from a steady 12 mph.
- Direction: check how the wind will affect key holes.
- Changes during the day: wind often increases in the afternoon, especially on coasts.
| Wind speed | Effect on golf |
|---|---|
| Under 10 mph | Minor; small adjustments |
| 10–20 mph | Noticeable; club up and down, aim off |
| 20–30 mph | Strong; low shots and big adjustments |
| Over 30 mph | Very difficult; consider rescheduling |

Rain
- Probability: a 40% chance of rain means a 40% chance of rain at that location in that period, not rain for 40% of the time.
- Amount: check expected rainfall to judge how wet the course will be.
- Timing: hourly forecasts help choose a tee time between showers.
- Course conditions: heavy rain can lead to cart restrictions and preferred lies. Read playing golf in bad weather.
Pack waterproofs if there's any real chance of rain. Read golf rain gear guide.
Lightning
- Check storm forecasts before you play.
- Use lightning alerts on weather apps.
- Know where shelters are on the course.
- Follow the course's siren signals. Read golf course safety.
Temperature
- Cold: the ball flies shorter, the body is stiffer and greens may be slower. Read winter golf guide.
- Heat: the ball flies further, but heat illness is a risk. Read hot-weather golf.
- Humidity: makes heat feel worse and affects grip.
Fog and frost
Morning fog and frost can delay starts. Check forecasts for clearing times. Read playing golf in fog.
Using weather apps and radar
- Radar maps show showers approaching in real time.
- Hourly forecasts help plan tee times.
- Wind maps show direction and strength.
- Alerts warn of lightning and severe weather.
Using weather apps for general forecasts is fine, but using a device to measure wind speed during a competition round isn't allowed. Read golf apps and online tools.
Planning your round
- Check the forecast the day before and the morning of your round.
- Choose a tee time that avoids the worst weather.
- Pack for the conditions: layers, waterproofs, sun protection.
- Plan your strategy: adjust for wind and firmness. Read golf course management.
Frequently asked questions
Can I use a weather app during a competition?
Checking general forecasts for safety is usually fine, but measuring wind or using devices for playing advice isn't allowed.
What wind speed is too strong for golf?
Many golfers find over 30 mph very difficult. Safety, such as falling branches, also matters.
Does rain make the ball go shorter?
Wet conditions reduce roll and can reduce carry slightly.
The bottom line
Read forecasts carefully: wind gusts, rain timing, temperature and lightning risk. Use radar during the round, pack for the conditions and never take risks with storms. For seasonal advice, read best golf destinations by month.
