What NOAA buoy 45137 measures
As a NOAA meteorological station, 45137 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 Huron
Lake Huron pairs a big open main basin with the sheltered waters of Georgian Bay and the North Channel, so conditions vary a lot with where you are. The open lake builds steep, short-period seas on a sustained blow — check the buoy nearest your water and mind the wind direction.
Frequently asked questions
- What is the water temperature at Georgian Bay?
- Sea surface temperature at Georgian Bay was 54°F. Measured October 19, 2026 at 19:00 UTC by NOAA station 45137 (Georgian Bay). NDBC measures this near the surface, at a depth that varies by station.
- What is the air temperature at Georgian Bay?
- Air temperature at Georgian Bay was 55°F. Measured October 19, 2026 at 19:00 UTC by NOAA station 45137 (Georgian Bay).
- What is the wind doing at Georgian Bay?
- Wind at Georgian Bay was from the W at 13 mph, with peak gusts to 16 mph. Measured October 19, 2026 at 19:00 UTC by NOAA station 45137 (Georgian 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 Georgian Bay?
- Significant wave height at Georgian Bay was 2.0 ft, with a 3-second dominant period. Measured October 19, 2026 at 19:00 UTC by NOAA station 45137 (Georgian Bay). Significant wave height is the average of the highest one-third of waves — individual waves can be larger.
- What is the barometric pressure at Georgian Bay?
- Sea-level pressure at Georgian Bay was 30.35 inHg (1027.9 hPa). Measured October 19, 2026 at 19:00 UTC by NOAA station 45137 (Georgian Bay). NDBC reports pressure reduced to sea level rather than the raw reading at the station.
