Questions about buoy 44009

Where is buoy 44009?

NDBC station 44009 is moored at 38.460°N, 74.692°W — DELAWARE BAY 26 NM Southeast of Cape May, NJ, in 24 m of water. The closest other reporting station is Bethany Beach, DE (263) (44084), 17 nm to the WNW.

Does buoy 44009 report wave height?

Not in its current configuration — 44009 reports wind, pressure and temperature but has no wave sensor. For sea state use the nearest wave buoy listed under Nearby.

How windy is it at Delaware Bay buoy 44009?

Wind at 44009 is 19.4 knots from the ESE, gusting 23.3. The strongest gust in the past 21 days was 43 knots.

Why are some fields blank?

Not every sensor reports on every transmission. NDBC prints “-” (or “MM” in the raw feed). A field that stays blank for days usually means a sensor fault; NDBC lists outages on its station status page.
