What NOAA buoy 44099 measures
As a NOAA meteorological station, 44099 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 the western North Atlantic
Conditions along the Atlantic coast are driven by swell direction and the shifting western edge of the Gulf Stream. Northeast winds against an outgoing tide stack up steep, dangerous seas at inlets, and water temperature can change 10–20°F over just a few miles as the Gulf Stream boundary moves.
Frequently asked questions
- What is the water temperature at Cape Henry?
- Sea surface temperature at Cape Henry was 67°F. Measured October 19, 2026 at 18:26 UTC by NOAA station 44099 (Cape Henry, VA). NDBC measures this near the surface, at a depth that varies by station.
- How big are the waves at Cape Henry?
- Significant wave height at Cape Henry was 8.5 ft, with a 13-second dominant period. Measured October 19, 2026 at 18:26 UTC by NOAA station 44099 (Cape Henry, VA). 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 Cape Henry?
- Waves at Cape Henry were arriving from 89° true (E) at the dominant period. Measured October 19, 2026 at 18:26 UTC by NOAA station 44099 (Cape Henry, VA).
- What is the swell at Cape Henry?
- The swell at Cape Henry had a significant height of 4.3 ft at a 13-second peak period, arriving from the E. Measured October 19, 2026 at 18:26 UTC by NOAA station 44099 (Cape Henry, VA). NDBC separates swell from locally generated wind waves using a spectral estimate.
- How much wind chop is at Cape Henry?
- The wind-wave component at Cape Henry had a significant height of 7.5 ft at a 7-second peak period, from the ENE. Measured October 19, 2026 at 18:26 UTC by NOAA station 44099 (Cape Henry, VA). Swell and wind-wave heights combine in quadrature, not by addition.
- Is it swell or wind chop at Cape Henry?
- NDBC classified the sea state at Cape Henry as average, with a significant wave height of 8.5 ft. Measured October 19, 2026 at 18:26 UTC by NOAA station 44099 (Cape Henry, VA). The classification describes wave steepness relative to period, not wave size.
