What NOAA buoy 44097 measures
As a NOAA meteorological station, 44097 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 Block Island?
- Sea surface temperature at Block Island was 61°F. Measured October 19, 2026 at 19:30 UTC by NOAA station 44097 (Block Island, RI (154)). NDBC measures this near the surface, at a depth that varies by station.
- What is the air temperature at Block Island?
- Air temperature at Block Island was 57°F. Measured October 19, 2026 at 19:30 UTC by NOAA station 44097 (Block Island, RI (154)).
- How big are the waves at Block Island?
- Significant wave height at Block Island was 8.2 ft, with a 10-second dominant period. Measured October 19, 2026 at 19:30 UTC by NOAA station 44097 (Block Island, RI (154)). 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 Block Island?
- Waves at Block Island were arriving from 135° true (SE) at the dominant period. Measured October 19, 2026 at 19:30 UTC by NOAA station 44097 (Block Island, RI (154)).
- What is the swell at Block Island?
- The swell at Block Island had a significant height of 3.9 ft at a 10-second peak period, arriving from the SE. Measured October 19, 2026 at 19:30 UTC by NOAA station 44097 (Block Island, RI (154)). NDBC separates swell from locally generated wind waves using a spectral estimate.
- How much wind chop is at Block Island?
- The wind-wave component at Block Island had a significant height of 7.2 ft at a 10-second peak period, from the SE. Measured October 19, 2026 at 19:30 UTC by NOAA station 44097 (Block Island, RI (154)). Swell and wind-wave heights combine in quadrature, not by addition.
- Is it swell or wind chop at Block Island?
- NDBC classified the sea state at Block Island as average, with a significant wave height of 8.2 ft. Measured October 19, 2026 at 19:30 UTC by NOAA station 44097 (Block Island, RI (154)). The classification describes wave steepness relative to period, not wave size.
- Where is NOAA buoy 44097 located?
- Block Island, RI (154) (44097) reports from 40.966°N, 71.123°W in the western North Atlantic (Rhode Island).
- How often is NOAA buoy 44097 updated?
- Station 44097 typically reports new observations about every 10 minutes. Big Buoy refreshes continuously so you always see the latest readings, alongside 7-day tide predictions and a solunar table for the area.
- What does NOAA buoy 44097 measure?
- Big Buoy shows wind, barometric pressure, air and water temperature, and wave height and period where available for Block Island, RI (154), plus 7-day tides, solunar peak windows, and a multi-day weather outlook.
