What NOAA buoy 4403587 measures
As a NOAA meteorological station, 4403587 reports wind speed, gusts and direction, barometric pressure, air and water temperature, and — where wave sensors are fitted — significant wave height, swell period, and wave direction.
What to watch in Lake Superior
Lake Superior is the coldest, deepest, and largest of the Great Lakes, with enough open water and fetch to build true offshore seas. Water stays cold most of the year and storms move through fast, so a sustained blow can raise steep, short-period waves with little warning — read wind, fetch, and sea state together before heading out.
Frequently asked questions
- What is the water temperature at Whitefish Bay?
- Sea surface temperature at Whitefish Bay was 55°F. Measured October 19, 2026 at 20:20 UTC by NOAA station 4403587 (Whitefish Bay). NDBC measures this near the surface, at a depth that varies by station.
- What is the air temperature at Whitefish Bay?
- Air temperature at Whitefish Bay was 54°F. Measured October 19, 2026 at 20:20 UTC by NOAA station 4403587 (Whitefish Bay).
- What is the wind doing at Whitefish Bay?
- Wind at Whitefish Bay was from the NNW at 11 mph, with peak gusts to 15 mph. Measured October 19, 2026 at 20:20 UTC by NOAA station 4403587 (Whitefish Bay). NDBC records wind at the station’s anemometer height, which is not the 10 m height used in marine forecasts.
- How big are the waves at Whitefish Bay?
- Significant wave height at Whitefish Bay was 1.3 ft, with a 3-second dominant period. Measured October 19, 2026 at 20:20 UTC by NOAA station 4403587 (Whitefish Bay). Significant wave height is the average of the highest one-third of waves — individual waves can be larger.
- Which direction are the waves coming from at Whitefish Bay?
- Waves at Whitefish Bay were arriving from 1° true (N) at the dominant period. Measured October 19, 2026 at 20:20 UTC by NOAA station 4403587 (Whitefish Bay).
- What is the barometric pressure at Whitefish Bay?
- Sea-level pressure at Whitefish Bay was 30.37 inHg (1028.3 hPa). Measured October 19, 2026 at 20:20 UTC by NOAA station 4403587 (Whitefish Bay). NDBC reports pressure reduced to sea level rather than the raw reading at the station.
