What NOAA buoy 41117 measures
As a NOAA meteorological station, 41117 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 Gulf of Mexico
The Gulf’s shallow, broad shelf means seas build and lay down quickly with the wind — short-period chop is the norm rather than long ocean swell. Summer afternoons bring fast-developing thunderstorms, so watch barometric pressure and wind trends closely before heading out.
Frequently asked questions
- What is the water temperature at St. Augustine?
- Sea surface temperature at St. Augustine was 78°F. Measured October 19, 2026 at 20:56 UTC by NOAA station 41117 (St. Augustine, FL (194)). NDBC measures this near the surface, at a depth that varies by station.
- How big are the waves at St. Augustine?
- Significant wave height at St. Augustine was 7.2 ft, with a 13-second dominant period. Measured October 19, 2026 at 20:56 UTC by NOAA station 41117 (St. Augustine, FL (194)). 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 St. Augustine?
- Waves at St. Augustine were arriving from 69° true (ENE) at the dominant period. Measured October 19, 2026 at 20:56 UTC by NOAA station 41117 (St. Augustine, FL (194)).
- What is the swell at St. Augustine?
- The swell at St. Augustine had a significant height of 3.6 ft at a 13-second peak period, arriving from the ENE. Measured October 19, 2026 at 20:56 UTC by NOAA station 41117 (St. Augustine, FL (194)). NDBC separates swell from locally generated wind waves using a spectral estimate.
- How much wind chop is at St. Augustine?
- The wind-wave component at St. Augustine had a significant height of 6.2 ft at a 6-second peak period, from the NNE. Measured October 19, 2026 at 20:56 UTC by NOAA station 41117 (St. Augustine, FL (194)). Swell and wind-wave heights combine in quadrature, not by addition.
- Is it swell or wind chop at St. Augustine?
- NDBC classified the sea state at St. Augustine as average, with a significant wave height of 7.2 ft. Measured October 19, 2026 at 20:56 UTC by NOAA station 41117 (St. Augustine, FL (194)). The classification describes wave steepness relative to period, not wave size.
- Where is NOAA buoy 41117 located?
- St. Augustine, FL (194) (41117) reports from 29.999°N, 81.079°W in the Gulf of Mexico (Florida).
- How often is NOAA buoy 41117 updated?
- Station 41117 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 41117 measure?
- Big Buoy shows wind, barometric pressure, air and water temperature, and wave height and period where available for St. Augustine, FL (194), plus 7-day tides, solunar peak windows, and a multi-day weather outlook.
- Is Big Buoy free to use?
- Yes. Live data for St. Augustine, FL (194) and every other NOAA buoy is free with no account required. Big Buoy Pro adds the Wind Tab, the Depth Chart, satellite overlays (sea surface temp, chlorophyll, currents), 16-day forecasts, and forecast model switching.
