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.
The site currently monitors 18 coastal weather stations and 19 moored buoys — primarily along British Columbia's Pacific coast, with initial coverage in the Atlantic and Arctic.

Atlantic & Arctic
Early coverage includes Banquereau Bank (Atlantic) and Resolute (Arctic), with more stations planned as ECCC data feeds are integrated.
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.
