Questions about buoy 44098

Where is buoy 44098?

NDBC station 44098 is moored at 42.800°N, 70.169°W — Jeffrey's Ledge, NH (160), in 76.5 m of water. The closest other reporting station is Buoy A01 - Massachusetts Bay (44029), 24 nm to the SW.

How big are the waves at the Jeffreys Ledge buoy right now?

As of the Aug 27, 10:30 PM EDT report, 44098 shows 3.6 ft significant wave height on a 12-second dominant period from the E. Over the past 46 days, 45% of readings were under 2 ft and the biggest day reached 6.9 ft.

What is the water temperature at Jeffreys Ledge buoy?

Water temperature at the buoy is 68.2°F. That is 2°F warmer than on July 14.

Why are some fields blank?

Waves are sampled every 30 minutes, so most 10-minute rows carry no value for them. 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.

The buoy says what it did. This says what it'll do.

The buoy reads the present. For what Jeffreys Ledge will do tomorrow, and whether your boat should be out in it, that's the app.

Per-vessel go / no-go for Jeffreys Ledge

SeaLegs AI turns 12+ forecast models — and the buoy you just read — into a verdict for your boat, not a generic sea state.
