What NOAA buoy 44258 measures
As a NOAA meteorological station, 44258 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 Halifax Harbour?
- Sea surface temperature at Halifax Harbour was 53°F. Measured October 19, 2026 at 22:00 UTC by NOAA station 44258 (Halifax Harbour). NDBC measures this near the surface, at a depth that varies by station.
- What is the air temperature at Halifax Harbour?
- Air temperature at Halifax Harbour was 53°F. Measured October 19, 2026 at 22:00 UTC by NOAA station 44258 (Halifax Harbour).
- What is the wind doing at Halifax Harbour?
- Wind at Halifax Harbour was from the S at 9 mph, with peak gusts to 11 mph. Measured October 19, 2026 at 22:00 UTC by NOAA station 44258 (Halifax Harbour). 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 Halifax Harbour?
- Significant wave height at Halifax Harbour was 2.3 ft, with a 5-second dominant period. Measured October 19, 2026 at 22:00 UTC by NOAA station 44258 (Halifax Harbour). Significant wave height is the average of the highest one-third of waves — individual waves can be larger.
- What is the barometric pressure at Halifax Harbour?
- Sea-level pressure at Halifax Harbour was 30.40 inHg (1029.4 hPa). Measured October 19, 2026 at 22:00 UTC by NOAA station 44258 (Halifax Harbour). NDBC reports pressure reduced to sea level rather than the raw reading at the station.

- Halifax Harbour (44258) reports from 44.500°N, 63.400°W in the western North Atlantic.
- How often is NOAA buoy 44258 updated?
- Station 44258 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 44258 measure?
- Big Buoy shows wind, barometric pressure, air and water temperature, and wave height and period where available for Halifax Harbour, plus 7-day tides, solunar peak windows, and a multi-day weather outlook.
