What NOAA buoy 42354 measures
As a NOAA meteorological station, 42354 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 Chandeleur Island SE?
- Sea surface temperature at Chandeleur Island SE was 80°F. Measured October 19, 2026 at 19:30 UTC by NOAA station 42354 (Chandeleur Island SE, LA (279)). NDBC measures this near the surface, at a depth that varies by station.
- What is the air temperature at Chandeleur Island SE?
- Air temperature at Chandeleur Island SE was 73°F. Measured October 19, 2026 at 19:30 UTC by NOAA station 42354 (Chandeleur Island SE, LA (279)).
- How big are the waves at Chandeleur Island SE?
- Significant wave height at Chandeleur Island SE was 6.6 ft, with a 7-second dominant period. Measured October 19, 2026 at 19:30 UTC by NOAA station 42354 (Chandeleur Island SE, LA (279)). 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 Chandeleur Island SE?
- Waves at Chandeleur Island SE were arriving from 103° true (ESE) at the dominant period. Measured October 19, 2026 at 19:30 UTC by NOAA station 42354 (Chandeleur Island SE, LA (279)).
- What is the swell at Chandeleur Island SE?
- The swell at Chandeleur Island SE had a significant height of 0.7 ft at a 10-second peak period, arriving from the SE. Measured October 19, 2026 at 19:30 UTC by NOAA station 42354 (Chandeleur Island SE, LA (279)). NDBC separates swell from locally generated wind waves using a spectral estimate.
- How much wind chop is at Chandeleur Island SE?
- The wind-wave component at Chandeleur Island SE had a significant height of 6.6 ft at a 7-second peak period, from the ESE. Measured October 19, 2026 at 19:30 UTC by NOAA station 42354 (Chandeleur Island SE, LA (279)). Swell and wind-wave heights combine in quadrature, not by addition.
- Is it swell or wind chop at Chandeleur Island SE?
- NDBC classified the sea state at Chandeleur Island SE as steep, with a significant wave height of 6.6 ft. Measured October 19, 2026 at 19:30 UTC by NOAA station 42354 (Chandeleur Island SE, LA (279)). The classification describes wave steepness relative to period, not wave size.
- Where is NOAA buoy 42354 located?
- Chandeleur Island SE, LA (279) (42354) reports from 29.579°N, 88.645°W in the Gulf of Mexico (Louisiana).
- How often is NOAA buoy 42354 updated?
- Station 42354 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 42354 measure?
- Big Buoy shows wind, barometric pressure, air and water temperature, and wave height and period where available for Chandeleur Island SE, LA (279), plus 7-day tides, solunar peak windows, and a multi-day weather outlook.
- Is Big Buoy free to use?
- Yes. Live data for Chandeleur Island SE, LA (279) 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.
