Rhode Island marine forecasts: common questions
Is there a small craft advisory off Rhode Island right now?
1 of the 2 Rhode Island marine zones is under an active advisory or warning, Block Island Sound (small craft advisory). Each zone page shows the expiry time and the full text.
How windy is it on the Rhode Island coast right now?
Buoys off Rhode Island are reporting 4 to 7 knots, the strongest at Block Island Sound. A knot is 1.15 mph, so 20 knots is about 23 mph. Wind measured offshore is usually stronger than the same wind felt in a harbor.
How rough are the seas off Rhode Island today?
The highest seas measured right now are 3 ft off Block Island Sound, out of the 2 of 2 Rhode Island zones with a wave-capable buoy nearby. Seas are significant wave height, the average of the highest third of the waves, so individual waves run noticeably higher than the figure.
Who issues the marine forecast for Rhode Island?
The National Weather Service, from its Boston/Norton, MA office. Each of the 2 zones on this page gets its own bulletin in a legacy teletype format, reproduced here in full underneath the charts and the live buoy readings.
