* WHAT...Up to one foot of inundation above ground level expected in low-lying areas near shorelines and tidal waterways (2.9 to 13.0 feet Mean Lower Low Water) around the evening high tides. * WHERE...Eastern Essex MA, Suffolk MA, Eastern Norfolk MA, Eastern Plymouth MA, Barnstable MA and Dukes MA Counties. * WHEN...From 9 PM EDT this evening through late Monday night. The evening high tide periods tonight, Sunday night and Monday night are of the greatest concern. * IMPACTS...Shallow pockets of flooding less than one foot deep affects the lowest lying areas along the coast, including Morrissey Boulevard in Boston. Most roads remain passable. Flooding up to one foot deep affects coastal roads on the North Shore from Salem to Gloucester and Newburyport. Rough surf will cause flooding on some coastal roads around the time of high tide due to splashover.

Effective: Sat June 13, 2026, 8:01 PM
Expires: Sun June 14, 2026, 5:00 AM

* WHAT...Warm air temperatures in the 80s to near 90 may cause people to underestimate the dangers of the cold water temperatures in the upper 50s and lower 60s. * WHERE...In Maine, Coastal York, Coastal Cumberland, Sagadahoc, Lincoln, Knox and Coastal Waldo Counties. In New Hampshire, Coastal Rockingham County. * WHEN...From Sunday morning through Sunday evening. * IMPACTS...The cold water temperatures can quickly cause hypothermia to anyone immersed in the water. When the water temperature is below 60 degrees, the average submerged person could lose dexterity within minutes and be unable to accomplish simple tasks. Anyone on boats or paddlecraft should use extreme caution to avoid this threat.

A Beach Hazards Statement is issued on days when a significant number of boats and paddlecraft are expected to be out on the water and when warm air temperatures may cause people to underestimate the danger of the cold water. Paddle smart from the start. Always wear your life jacket. Be aware of wind conditions, tides, and localized currents. All boaters and paddlers are highly encouraged to contact the U.S. Coast Guard Auxiliary or U.S. Power Squadrons at https://cgaux.org/vsc/ to receive a FREE vessel check. This is a convenient, no consequence way to ensure your vessel is outfitted with all required safety equipment. Additionally, please label your paddlecraft with your contact information (IF FOUND Sticker) in the event it is found adrift on the water.

The times presented here are based upon the solunar theory, which is the idea that the movements of fish and other animals are affected by the location of the sun and moon. The major periods are believed to be the times of the greatest animal activity and occur when the moon is directly overhead or underfoot (lunar transits). The minor periods also see increased activity and occur when the moon is rising or setting. The strongest activity occurs during full or new moons, and the weakest during quarter or three quarter moons. This is indicated by the Action Rating.
