What NOAA buoy 45135 measures
As a NOAA meteorological station, 45135 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 Ontario
Lake Ontario is deep and steep-sided, so it stratifies strongly in summer and holds cold water below the thermocline while wind-driven upwelling swings surface temperature along the shore. Seas build quickly on a sustained westerly or northeasterly blow — read wind and water temperature together before you go.
Frequently asked questions
- What is the water temperature at Prince Edward Pt?
- Sea surface temperature at Prince Edward Pt was 57°F. Measured October 19, 2026 at 19:00 UTC by NOAA station 45135 (Prince Edward Pt). NDBC measures this near the surface, at a depth that varies by station.
- What is the air temperature at Prince Edward Pt?
- Air temperature at Prince Edward Pt was 58°F. Measured October 19, 2026 at 19:00 UTC by NOAA station 45135 (Prince Edward Pt).
- What is the wind doing at Prince Edward Pt?
- Wind at Prince Edward Pt was from the SW at 9 mph, with peak gusts to 11 mph. Measured October 19, 2026 at 19:00 UTC by NOAA station 45135 (Prince Edward Pt). 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 Prince Edward Pt?
- Significant wave height at Prince Edward Pt was 2.3 ft, with a 4-second dominant period. Measured October 19, 2026 at 19:00 UTC by NOAA station 45135 (Prince Edward Pt). Significant wave height is the average of the highest one-third of waves — individual waves can be larger.
- What is the barometric pressure at Prince Edward Pt?
- Sea-level pressure at Prince Edward Pt was 30.37 inHg (1028.3 hPa). Measured October 19, 2026 at 19:00 UTC by NOAA station 45135 (Prince Edward Pt). NDBC reports pressure reduced to sea level rather than the raw reading at the station.
