About

What This Is

Environment and Climate Change Canada (ECCC) publishes real-time observations from a network of coastal weather stations and moored buoys. That data is authoritative and freely available — but government portals can be slow to navigate, especially when you need a quick read on conditions before heading out on the water.

Marine Conditions takes that same data and presents it in a clean, easy-to-read format for mariners, sailors, paddlers, and anyone curious about what the ocean is doing right now. Wind speed and direction, wave heights, sea and air temperature, barometric pressure — at a glance, on any device.

Where the Data Comes From

All data is sourced directly from ECCC's real-time observation network. Nothing is modified or estimated — what you see is exactly what ECCC publishes. The network includes both land-based coastal weather stations and moored buoys anchored at key offshore locations.

Stations currently shown:

• Sisters Island — Strait of Georgia
• Ballenas Island — Strait of Georgia
• Discovery Island — southern tip of Vancouver Island

Buoys currently shown:

• Halibut Bank — central Strait of Georgia
• La Perouse Bank — outer coast, southwest Vancouver Island
• Sentry Shoal — northern Strait of Georgia

How Fresh Is the Data

Observations are collected from ECCC hourly and stored so the dashboard loads quickly. The page refreshes automatically every 5 minutes, so you're always seeing the latest available reading without needing to reload. History charts show up to 48 hours of past observations for any station or buoy.

Coverage

The site starts with stations and buoys along the British Columbia coast. ECCC operates observation networks across all of Canada's coastlines — Atlantic, Pacific, and Arctic — and the goal is to expand coverage to more Canadian regions over time.
