NOAA Ocean Prediction Center

NOAA Ocean Prediction Center

NOAA's Ocean Prediction Center (OPC) publishes marine weather analyses and forecasts for Atlantic, Pacific and Alaska/Arctic waters, including graphical products, briefing pages and links to digital forecast data used by mariners. The site is a public US-government product page; no account is required to view the forecasts.

Coverage

OPC analysis and forecast products for ocean basins as linked from ocean.weather.gov, including Atlantic, Pacific and Alaska/Arctic product sets. Update cadence follows NWS/OPC forecast cycles; exact history depth for each product is not summarized on the homepage.

Verdict

This is an official US marine-weather and sea-state forecast hub for open-ocean routing risk, useful next to NDBC realtime buoy observations and ERDDAP ocean fields. Content is US government public information on the OPC site; Signal Lab links to the official hub rather than mirroring forecast graphics.
