Weather & Court Wind

Read the Conditions Before You Play

A local forecast sits right at the top of your Matches screen, and a tap opens Court & Wind — a live court that orients to your phone, shows where the sun is, and demonstrates exactly how the wind will move the ball on your serve and groundstrokes. Powered by Apple WeatherKit.

The next 3 hours, at a glance

A scrolling strip at the top of Matches shows your local forecast in 30-minute steps for the next three hours — temperature, wind, cloud cover, chance of rain and humidity. The condition icon is even tinted by how much sun you'll get: bright orange for full shine, softer for partial, grey when it's overcast.

  • Six 30-minute slots covering the next three hours.
  • Temperature, wind, cloud, chance of precipitation and humidity per slot.
  • Units follow your region — °C/°F and km/h or mph automatically.
  • Forecasts are cached for 10 minutes to stay fast and battery-friendly.

Court & Wind: see how the ball moves

Tap the forecast to open a top-down court that orients to your phone's compass — point the top of the phone down the court and the wind arrow, the sun and the North marker line up with the real world. A ball-drift demo then draws the no-wind path and the wind-affected path side by side, with the sideways and lengthwise drift in metres.

  • Sun position (azimuth & elevation) so you know which end faces the glare.
  • Ball-drift demo for Serve and Groundstroke, with an adjustable ball-speed slider.
  • Per-end advice: tailwind vs headwind, crosswind push, and sun in your eyes.
  • Switch ends and lock orientation to preview the other side of the court.

Privacy: your location is used only for the forecast

CourtsidePlay requests your location only to fetch the local forecast from Apple WeatherKit and to compute the sun's position. It isn't stored or uploaded anywhere, and the Court & Wind compass works entirely on-device. The ball-drift figures are an approximate aerodynamic model meant as a practical guide, not a lab measurement.
