Fills temperature, humidity, pressure, altitude and wind speed from your location.
Downwind 0.0 m/s / Crosswind 0.0 m/s
Enter your carry (not including roll) in calm conditions on flat ground at 15 °C at sea level. Set a club to 0 to hide it.
Clubs set to 0 (ones you do not carry) are left alone.
Estimated from commonly quoted average driver distances by age. These are not per-club survey data, so overwrite them with your own numbers if you know them.
The temperature at which the carries above were measured. Set it to match your own conditions if you play somewhere warm.
In these conditions the carry is essentially unchanged.

Roughly the club you would normally hit that far・Distance [m]
Air density is computed from the conditions you enter, and the carry is obtained by numerically integrating the equations of motion including drag and Magnus lift. For each club the ball speed is solved so that, under your baseline conditions (15 °C, sea level, 50% humidity, no wind), the flight matches the carry you entered. The same ball speed is then flown again under the actual conditions, so errors in the absolute aerodynamic coefficients largely cancel in the ratio.
The flight model is checked against published launch-monitor tour averages (driver apex 29 m, descent angle 39°, hang time 6.4 s).
Assumptions: the wind is treated as uniform with height, and each club uses representative launch angle and spin. In reality wind is stronger higher up, and launch and spin vary shot to shot. Roll is not included.
What this tool does
Enter the temperature, altitude, pressure, humidity, wind and elevation change, and it simulates the ball flight to show how far each club’s carry moves from your baseline — and which club today’s conditions make it play like. No sign-up, no install.
How much carry the cold takes away
Colder air is denser, so the ball carries shorter. The loss is computed per club, which makes it a practical guide to club selection in winter.
How much further the ball goes at altitude
Higher ground means lower pressure and thinner air, so the ball carries further. You can check the familiar "a club longer up in the mountains" against real numbers.
What the wind actually costs
Give a wind speed and direction and it computes both the change in carry and the sideways drift. The asymmetry — a headwind hurting more than a tailwind helps — comes out as a figure.
Turn elevation change into distance
Enter the height difference to the green and it works out how the carry to the landing point changes, so you can see how much shorter an uphill shot plays and how much further a downhill one goes.
Fill it in from the weather where you are
Allow location access and it pulls in the temperature, pressure, humidity and wind for your position (via Open-Meteo), ready to use at the range or on the course.
Frequently asked questions
What if I do not know my own carry distances?
The defaults are typical figures for a male amateur. Use launch monitor numbers if you have them, otherwise the distance you normally reach. The tool works on the ratio — the percentage the conditions change things by — not the absolute value, so the trend still holds if your numbers are a little off.
Do I have to enter the pressure?
No. Give the altitude and the standard-atmosphere pressure is computed from it. Only override it if you have a barometer reading.
Does it include roll-out?
No. It computes carry to the landing point. The descent angle is shown as well, so you can judge how readily the ball will stop.
Is not the wind stronger higher up?
It is, but this tool treats the wind as constant with height. A genuinely high ball will be affected more than the calculation says. The assumptions are stated under the results.
Does it work offline?
Once you have opened it, the ball-flight calculation runs without a connection. Only pulling in the local weather needs one.
