Surf Forecast: 7th Ave, Belmar, NJ

Forecast Analysis

Alright, Jersey shredders, get ready to wax up those boards because we've got a fun few days ahead, despite a bit of a mixed bag! The water temperature is sitting beautifully in the low 70s Fahrenheit, so no need for thick rubber this week – maybe just a vest or a thin spring suit if you run cold. Air temperatures will be super comfortable, ranging from the mid-60s to mid-70s Fahrenheit, making for some epic sessions. Remember, I'm mapping the provided forecast data to the next 2-3 days from today, Thursday, September 18th, so let's dive into the specifics! Kicking things off this Thursday evening, September 18th, we're looking at some solid shoulder-to-head high waves, initially around 5.8 feet and slowly backing down to about 5 feet by sunset. The swell is coming in primarily from the East to East-Southeast, with quick periods hovering around 5.7 to 5.9 seconds. Expect a bit of texture though, as the winds will be a moderate NNE at 11-14 mph, easing to around 9.5 mph by dusk. These cross-shore winds mean the waves won't be perfectly groomed, but with the tide pushing in towards a high around 5:48 PM EDT, we should see some fun, albeit slightly bumpy, peaks to bash. Sunrise today was at 6:41 AM EDT, and sunset is at 7:01 PM EDT. Friday, September 19th, sees a gradual decrease in wave height but potentially cleaner conditions. Early birds might find waves in the 4 to 5-foot range, tapering off to under 3 feet by the evening. The East to East-Southeast swell remains consistent, with periods starting around 5.9 seconds and stretching out to a more workable 7 seconds later in the day, which should give those waves a bit more punch. The good news for wave shape is the lighter winds! We're expecting very light Northerly winds at 5-7 mph in the morning, becoming an almost glassy ENE at a mere 2-3 mph by the afternoon, then shifting to a light SSE at 6.5 mph in the evening. While not perfectly offshore, these light winds mean much less chop, offering some cleaner faces to carve. High tide hits at 6:12 AM EDT, perfect for a sunrise session, then drops to a low at 12:21 PM EDT, before pushing back to high at 6:37 PM EDT, just as the sun sets at 7:00 PM EDT. Heading into Saturday, September 20th, conditions will be on the smaller side, mainly in the knee to waist-high range, starting around 2.7 feet and dropping to about 2.1 feet by mid-morning, with a slight bump to 2.4 feet in the late afternoon. The East to East-Southeast swell continues, offering periods in the 6.7 to 7.1-second range. Now, here's the kicker: for those dedicated enough, there's a very brief window of true offshore winds in the pre-dawn hours! From approximately 12 AM to 2 AM EDT, we're looking at light West-Southwesterly to Westerly winds at around 4-5 mph. While the waves will be tiny, this could offer some super clean, albeit small, wedges. After this, winds shift to a cross-shore NW/NNE at 5-9 mph through the morning, moving to an ENE at 8-9 mph in the afternoon, bringing some inevitable chop. High tide is at 6:57 AM EDT, just after sunrise (6:43 AM EDT), before falling to low tide at 1:08 PM EDT. Sunset is at 6:58 PM EDT.

Best Time to Surf

For the absolute best opportunity to snag some quality rides, I'm calling **Friday, September 19th, around 6:00 AM to 8:00 AM EDT**. The high tide hitting at 6:12 AM EDT, coupled with the chest-high waves (around 3.7-3.9 feet) and very light Northerly winds (only about 6.5 mph), will provide the cleanest and most workable conditions of the forecast. The light cross-shore breeze won't completely ruin the shape, and the comfortable air and water temperatures will make for an epic start to your Friday!

Atlantic Tropical Report
Summary of current named storms in the Atlantic basin.

Tropical Storm Fiona is currently located in the central Atlantic, a considerable distance from the US East Coast. While Fiona is a named system, its current track and moderate intensity suggest it will likely generate only a subtle, long-period groundswell for Belmar, NJ over the next several days, without posing any direct threats or significant surf impacts.
