Two Right Whale Slow Zone Extensions: NE of Virginia Beach, VA and Cape Cod Bay, MA
Effective Through January 5
On December 21, 2025, the Cape Cod Bay acoustic buoy operated by the Woods Hole Oceanographic Institute (WHOI) and Massachusetts Division of Marine Fisheries detected the presence of right whales in Cape Cod Bay, MA. Also, the Cape Charles buoy operated by WHOI and NAVFAC Atlantic detected the presence of right whales northeast of Virginia Beach, VA. These right whale Slow Zones are in effect through January 5, 2026.
As a reminder, five additional Slow Zones are also currently in effect. Locations and effective dates are listed below.
Voluntary Right Whale “Slow Zone” Areas
Mariners are requested to avoid or transit at 10 knots or less inside the following Dynamic Management Areas and Slow Zones where endangered right whales have been detected. Vessel strikes are one of the primary causes of injury and death for right whales. Slower speeds are known to reduce the severity of impacts to whales when strikes occur and may provide boat and vessel operators an opportunity to avoid a collision.

Active Seasonal Management Areas
Mandatory speed restrictions of 10 knots or less (50 CFR 224.105) are in effect for most vessels 65 feet or longer in the following areas:
Mid-Atlantic: November 1-April 30
Southeast: November 15-April 15
North Atlantic right whales are on the move along the Atlantic coast of the United States. To protect right whales, regulations prohibit approaching or remaining within 500 yards (1,500 feet) of a right whale. That’s the length of about five football fields.
Endangered North Atlantic right whales are approaching extinction. There are approximately 380 individuals remaining, including fewer than 70 reproductively active females. Human impacts continue to threaten the survival of this species.
In August 2017, NOAA Fisheries declared the increase in right whale mortalities an Unusual Mortality Event, which helps the agency direct additional scientific and financial resources to investigating, understanding, and reducing the mortalities. This work is done in partnership with the Marine Mammal Stranding Network, Canada’s Department of Fisheries and Oceans, and outside experts from the scientific research community.
