What NOAA buoy 45142 measures
As a NOAA meteorological station, 45142 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 Erie
Lake Erie is the shallowest Great Lake, which makes it the fastest to turn dangerous: northwesterly winds can stack steep 4–6 ft seas in the western basin within hours, and wind-driven seiches shift water levels several feet end to end. Watch wind speed and direction closely and check the buoy in your basin.
Frequently asked questions
- What is the water temperature at Port Colborne?
- Sea surface temperature at Port Colborne was 61°F. Measured October 19, 2026 at 19:00 UTC by NOAA station 45142 (Port Colborne). NDBC measures this near the surface, at a depth that varies by station.
- What is the air temperature at Port Colborne?
- Air temperature at Port Colborne was 61°F. Measured October 19, 2026 at 19:00 UTC by NOAA station 45142 (Port Colborne).

- Wind at Port Colborne was from the W at 13 mph, with peak gusts to 16 mph. Measured October 19, 2026 at 19:00 UTC by NOAA station 45142 (Port Colborne). 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 Port Colborne?
- Significant wave height at Port Colborne was 2.0 ft, with a 4-second dominant period. Measured October 19, 2026 at 19:00 UTC by NOAA station 45142 (Port Colborne). Significant wave height is the average of the highest one-third of waves — individual waves can be larger.
- What is the barometric pressure at Port Colborne?
- Sea-level pressure at Port Colborne was 30.39 inHg (1029 hPa). Measured October 19, 2026 at 19:00 UTC by NOAA station 45142 (Port Colborne). NDBC reports pressure reduced to sea level rather than the raw reading at the station.
