Before you leave the dock
01 · Know
Today leads with one plain-language read built from current observations, the hourly forecast and official marine advisories. Advisories come first, and old or missing readings ask you to check again.
Wind, gusts, wave height and period, and water temperature sit underneath, each with its source and age.
02 · Plan
See how the week compares, from a rough day to a calm one, then choose a window and turn it into a plan. Add a departure reminder and share it with your crew.
Save your boat and comfort limits, or start from an activity profile: cruising, sailing, paddling or fishing.
03 · Read the hours
Look closer at waves and wind against your boat's comfort limit. Scrub the day to see which hours fit, and which ones call for judgment.
The source and age of each reading stay in view, and missing readings stay missing.
04 · Go
Start an outing to keep your return time, sunset and the changing forecast in view. Keep saved plans, your active outing and past rides together.
Mark a moment, prepare a message for your shore contact, and note how the ride felt for next time.

Once you’re out there
Wavy can surface when to head back on the Lock Screen, in the Dynamic Island, and on Apple Watch. Widgets, Siri and Shortcuts keep the read within reach.
Location is used during an outing you start; the recorded route stays on your iPhone.
Head-back guidance is an estimate. The distance to the harbor is a straight line, not a navigable route.
Made for these waters
Explore U.S. Great Lakes harbors and Lake St. Clair. Compare nearby places, browse the lake map, and open available water-level, river, and lake-health context.
Wavy uses NOAA, National Weather Service, USGS, and Environment and Climate Change Canada sources. Coverage varies. A buoy may be miles offshore, a report may be delayed, and a forecast can change.
Wavy is a recreational planning companion. It does not identify safe routes or replace official forecasts, charts, marine notices, or conditions you observe on the water.
The animated lake scene is illustrative, not a camera feed or a measurement.
A few things to know
Yes. Wavy is free, with no account, ads, or in-app purchases. Conditions, forecasts, boats, plans, and outings are included.
You can choose a harbor manually. Nearby lookup is optional. If you start an outing, location supports the outing and optional route recording, including while the screen is locked. Finish the outing to stop tracking. Read the privacy details.
No. Wavy helps you interpret conditions for your plans. Always check official forecasts and advisories, use your own judgment, and carry suitable navigation and safety equipment. A favorable read is not a guarantee of safe conditions.
Conditions and planning are Wavy’s focus. Third-party webcams open the provider’s own page in an in-app Safari view. Wavy does not play or rebroadcast those feeds. Credited NOAA still images remain available in the app. That provider controls its content, availability, and privacy practices. A view may be delayed and should not be used to judge safety. Read the external-source notice.
