Synopsis
A low-pressure northeast of the region will continue moving eastward over the next few days, while high pressure builds across the western Atlantic. Light to moderate westerly to southwesterly winds today will become variable tonight, then gradually shift to a more easterly direction early this week. A northerly to northeasterly swell will peak today through tonight, maintaining hazardous conditions near exposed Atlantic coastal waters. Although seas will remain below Small Craft Advisory criteria, the longer-period swell will produce locally rough conditions, particularly across the offshore Atlantic waters. The northeasterly swell will gradually subside on Monday, with improving marine conditions expected thereafter. Showers and isolated thunderstorms will remain possible across the regional waters through midweek.

Does this page show NOAA warnings for this area?
Watches, warnings, and advisories for Coastal Waters east of Puerto Rico, around Vieques, and around and just north of Culebra and Saint John appear alongside the conditions, here and in the app. Pro also pushes NOAA watches, warnings, and advisories when they are issued.
Can I see the forecast against what buoy chav3 measured?
This page shows measurements only. Buoycast Pro charts the NOAA forecast against them so you can see where the two diverge.
Can I keep buoy chav3 for next time?
Save it as a favorite and Buoycast opens on the buoys you run.
What this buoy measures
This buoy is not reporting waves or water temperature. Conditions above come from the sensors it does carry, and the forecast, tides and sun times on this page are regional rather than measured at the buoy.
