Cosmic's Coast Map
Tides, campsites, fishing times and marine weather for paddlers, anglers, boaters and coastal explorers. Free to use online; offline maps for trips out of signal come with a Coast Map Pass.
The same map on a computer and on a phone: kayak campsites in the Broken Group, Barkley Sound.
Fishing
A Fishing tab with bite windows and the best hours of the day, and why. Local rules, fishing piers on the map, and a private catch log that shows your own patterns.
More about fishing →Tide alerts
A heads-up before high tide, low tide, slack water or a good fishing window, from 15 minutes to 2 hours ahead.
Wind, waves and weather
Hourly wind and gusts, waves, water temperature, rain radar and marine warnings on the map, plus the official marine forecast for your area.
Where to camp
Campsites coloured by what you need before landing: a fee or reservation, a permit or protocol, or free backcountry. Boat launches and marinas too.
Foraging
The best daylight low tides for the month, shellfish harvest areas and, where they're published, today's closures.
Offline with the Coast Map Pass
With a Coast Map Pass, pick your region once and the map, campsites and a year of tide tables download to your phone for trips out of signal.
Otter sightings
Where sea otters and river otters have been seen, filterable by season, with the best spots to look.
Plan a trip
Star the stations you'll pass, then “Prepare for trip” saves their forecasts. See where your phone is likely to have signal on the water.
Get started in three steps
- Open the map. It starts where you are (allow location) or in Victoria.
- Save your region from Layers before heading out of signal, ideally on Wi-Fi (offline maps come with a Coast Map Pass). That's your offline copy.
- Install it so it opens like an app and keeps your downloads.
