What NOAA buoy 45012 measures
As a NOAA meteorological station, 45012 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 East Lake America?
- Sea surface temperature at East Lake America was 56°F. Measured October 19, 2026 at 19:00 UTC by NOAA station 45012 (EAST Lake America - 20NM North Northeast of Rochester, NY). NDBC measures this near the surface, at a depth that varies by station.
- What is the air temperature at East Lake America?
- Air temperature at East Lake America was 58°F. Measured October 19, 2026 at 19:00 UTC by NOAA station 45012 (EAST Lake America - 20NM North Northeast of Rochester, NY).
- What is the wind doing at East Lake America?
- Wind at East Lake America was from the SSW at 4 mph, with peak gusts to 7 mph. Measured October 19, 2026 at 19:00 UTC by NOAA station 45012 (EAST Lake America - 20NM North Northeast of Rochester, NY). 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 East Lake America?
- Significant wave height at East Lake America was 2.3 ft, with a 5-second dominant period. Measured October 19, 2026 at 19:00 UTC by NOAA station 45012 (EAST Lake America - 20NM North Northeast of Rochester, NY). 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 East Lake America?
- Waves at East Lake America were arriving from 272° true (W) at the dominant period. Measured October 19, 2026 at 19:00 UTC by NOAA station 45012 (EAST Lake America - 20NM North Northeast of Rochester, NY).
- What is the barometric pressure at East Lake America?
- Sea-level pressure at East Lake America was 30.36 inHg (1028.1 hPa). Measured October 19, 2026 at 19:00 UTC by NOAA station 45012 (EAST Lake America - 20NM North Northeast of Rochester, NY). NDBC reports pressure reduced to sea level rather than the raw reading at the station.
- What is the swell at East Lake America?
- The swell at East Lake America had a significant height of 2.0 ft at a 5-second peak period, arriving from the W. Measured October 19, 2026 at 18:40 UTC by NOAA station 45012 (EAST Lake America - 20NM North Northeast of Rochester, NY). NDBC separates swell from locally generated wind waves using a spectral estimate.
- How much wind chop is at East Lake America?
- The wind-wave component at East Lake America had a significant height of 1.6 ft at a 4-second peak period, from the W. Measured October 19, 2026 at 18:40 UTC by NOAA station 45012 (EAST Lake America - 20NM North Northeast of Rochester, NY). Swell and wind-wave heights combine in quadrature, not by addition.
- Where is NOAA buoy 45012 located?
- EAST Lake America - 20NM North Northeast of Rochester, NY (45012) reports from 43.621°N, 77.401°W in Lake Ontario (New York).
