North Topsail Beach - Sea Dunes (S30F)

Stump Sound, North Carolina
Managed by The Swim Guide

North Topsail Beach is located on the northern end of Topsail Island. The island offers 26 miles of stunning coastline for both locals and visitors to enjoy. Note that there are no lifeguards on this quiet beach.

Local history has it that Topsail received its name from the many pirates that used to hid in the channel, waiting to ambush merchants ships. The merchants caught on to this hiding spot and kept a sharp watch for pirate ships’ topsails beyond the dunes when they sailed through the area.

Please be mindful of the sand dunes and the sea grasses. Dunes are extremely important to the ecosystem as well as to the properties on this low lying island, and breaches in the dunes leaves the beach extremely vulnerable to storms and floods. There is 500$ fine for walking on the dunes.

Topsail Island’s coastline is nesting beach for several species of threatened and endangered sea turtles. The Topsail Sea Turtle Project manages sea turtle activities along the 26 miles of coastline. Beach goers should take care to avoid disturbing nesting females, nests, and hatchlings during the nesting season (May1-August 31). During nesting and hatching season the North Carolina Wildlife Resources Commission strongly encourages North Topsail Beach visitors and residents use red filters on flashlights when walking on the beach at night and to ensure that lights facing the beach are turned off.

MONITORING FREQUENCY

North Topsail Beach - Sea Dunes (S30F) is sampled weekly from April 1st to October 31st

SOURCE INFORMATION

The N.C. Recreational Water Quality Program's staff monitor water quality at over 200 testing sites across the North Carolina. Monitoring locations are divided into 3 tiers based on their location and average public use. The more popular a beach is, the more strict the water quality standard will be.

The swimming season is from May - September, with April and October being considered shoulder months. All locations are sampled biweekly in October and once a month from November - March. Tier 1 beaches default to Tier 2 standards during the shoulder months and off season.

Tier 1 beaches are sampled weekly during the swimming season. All ocean beaches as well as brackish and freshwater beaches that average daily use during the swimming season will be marked Green when the geometric mean of 5 samples collected within 30 days contain less than 35 units / 100ml of water and when single sample test results are below 104 units / 100 ml of water. When water quality results fail to meet this standard, Swim Guide will show these beaches as "Red".

Tier 2 monitoring locations are sampled every two weeks April - October. These beaches will be marked "Green" when single sample results show enterococci levels below 276 untis / 100mL of water. When water quality results fail to meet this standard, Swim Guide will show these beaches as "Red".

A beach is marked Grey when there is no current or reliable monitoring information available.

Please note: Warning signs are only posted at beaches when a single sample results are above 500 units / 100 ml of water, however the press is notified to an alert when results show enterococci levels above 104 units / 100 ml of water for Tier 1 beaches and 276 units / 100 ml for Tier 2 beaches. Tier 3 beaches are in a separate region as boating is the primary use.

Recreational fishing permits are required for people over the age of 16 in North Carolina.

Swim Guide checks water quality results daily April - October.
