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

As of the Oct 11, 11:50 AM EDT report, 44013 shows 1.6 ft significant wave height on a 3-second dominant period from the SSE. Over the past 46 days, 51% of readings were under 2 ft and the biggest day reached 17.1 ft.

How windy is it at Boston buoy 44013?

What is the water temperature at Boston buoy?

Water temperature at the buoy is 58.3°F. That is 11°F cooler than on August 27.

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.
