How Ternmaps Works
Each surf break on the map has three LEDs. The number of lights tells you the size. The color tells you the quality.
Conditions update automatically every 10 minutes.
Reading the Lights
Size: Count the Lights
- 1 lightSmall

Quality: Check the Color
- Purple — All timeText your friend to come film.
- Green — GoodYou should probably get out there.
- Orange — OkaySurfable, but not great.
- Red — BadHeavy wind, no swell, etc.
Together they read like this:
- Three purple lights: Big and world class.
- One green light: Small, but good.
- Two red lights: Medium-sized, but poor.

Want to temporarily turn off the lights?
Tap the Tern in the bottom right corner of the map to turn the lights off. Tap again to turn them on.
The map can remain connected and powered while the lights are off.
