Questions about buoy 44097

Where is buoy 44097?

NDBC station 44097 is moored at 40.967°N, 71.124°W — Block Island, RI (154), in 49.4 m of water. The closest other reporting station is Buzzards Bay, MA (260) (44085), 26 nm to the N.

How big are the waves at the Block Island buoy right now?

As of the Sep 11, 6:00 AM EDT report, 44097 shows 3.6 ft significant wave height on a 8-second dominant period from the SSW. Over the past 46 days, 24% of readings were under 2 ft and the biggest day reached 9.5 ft.

What is the water temperature at Block Island buoy?

Water temperature at the buoy is 70.5°F. That is 1°F warmer than on July 28.

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.
