The New York coastal region is experiencing a dynamic weather pattern today as a low-pressure system shifts away, leaving a Small Craft Advisory in effect through this afternoon across the Western Long Island Sound and nearby coastal zones. Coastal temperatures are starting around 71°F near the beaches, with an expected daytime high climbing into the mid to upper 70s under mostly clear to partly cloudy skies. Coastal winds are currently blowing out of the west at 15 to 20 knots with gusts reaching up to 25 knots, though they will gradually diminish and shift northwest at 10 to 15 knots later this evening before dropping below 10 knots after midnight.
Ocean conditions display an average wave size of 2 to 3 feet within the more sheltered waterways and 3 to 5 feet along the more exposed south shore beaches. Real-time offshore data from the New York Harbor Entrance Buoy 44065 shows primary swell sizes of 2.5 feet coming from the northwest at a brief 4-second period, accompanied by a secondary easterly swell of 1 foot at 7 seconds. Further out, the Long Island Buoy 44025 registers a dominant south-southwest swell of 3 feet with an 8-second wave period, contributing to cleaner, longer-period lines along the ocean beaches compared to the choppier internal sounds.
Tidal cycles for the New York area dictate a brief low tide occurring at 5:12 AM, followed by a high tide peaking at 11:24 AM, before dropping back down to another low tide at 5:36 PM this evening. Tomorrow's marine outlook brings highly favorable conditions as high pressure briefly takes hold, causing winds to shift westerly at a gentle 5 to 10 knots and flattening seas down to 1 foot or less across most coastal zones.
