Caution: Right whales may be active in northeast waters year-round. NOAA may establish temporary Dynamic Management Areas (DMAs) to protect aggregations of right whales. Mariners are requested to transit DMAs at 10 knots or less when consistent with safe navigation. For information on currently active DMAs, go to: http://www.nmfs.noaa.gov/pr/shipstrike

Questions about buoy 44007

Where is buoy 44007?

NDBC station 44007 is moored at 43.525°N, 70.140°W — PORTLAND - 12 NM Southeast of Portland,ME, in 49 m of water. The closest other reporting station is Portland, ME (CASM1), 9 nm to the NNW.

How big are the waves at the Portland buoy right now?

As of the Aug 27, 10:30 PM EDT report, 44007 shows 3.9 ft significant wave height on a 5-second dominant period from the S. Over the past 46 days, 53% of readings were under 2 ft and the biggest day reached 6.2 ft.

How windy is it at Portland buoy 44007?

Wind at 44007 is 15.6 knots from the S, gusting 19.4. The strongest gust in the past 46 days was 37 knots.

What is the water temperature at Portland buoy?

Water temperature at the buoy is 63.9°F. That is 4°F warmer than on July 14.

Why are some fields blank?

Waves are sampled every 30 minutes and pressure tendency is computed hourly, 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.
