Black Rocks Jetty Surf Forecast and Surf Report

Yo, surfer dudes, Rusty here with the long-range look for Black Rocks Jetty. This is a solid run of swell, but you gotta pick your windows. The water is sitting at 77°, which is a touch warmer than usual for this time of year, so you might not need the thickest wetsuit.

Things kick off Friday morning the 10th with clean, glassy conditions. We’re looking at a 3ft SW groundswell with a long 15 second period, generating a moderate wave energy of 388. It’s a small start, but the glassy NNE breeze will make it rideable. The afternoon builds a little to 4ft, still glassy from the east, and the energy bumps up to 549. It’s a gentle intro.

Saturday the 11th is where it gets interesting. The morning brings a solid 5ft SW swell, still on that 15 second pulse, and the energy jumps significantly to 1117. With a glassy NNW breeze, this is going to be excellent for experienced surfers. The afternoon sees it push to 6ft and the energy to 1361, but a SSE wind swings in and makes it cross-on, so the morning session is the clear winner.

Sunday the 12th is a bit of a write-off for paddle surfing. The swell is pumping at 8ft with massive energy of 2699, but the wind is a cross-shore mess from the SSE, building to a moderate breeze. This setup is way more interesting for kite surfing than a traditional paddle session.

Monday the 13th is redemption. The swell drops to a still-strong 7ft, but the wind goes dead calm, making it glassy in the morning and then glassy from the SE in the afternoon. The energy is around 1600, so this is excellent surf for experienced folks, just with a chance of rain showers.

Tuesday the 14th stays good. The swell is 5ft in the morning and 5ft in the afternoon, both from the SSW with glassy conditions. The energy dips to 929 and then 745, but it’s still very good, clean surf.

Wednesday the 15th sees the swell back off to 4ft with a 12 second period and 439 energy. Dead calm in the morning means clean little waves, but the afternoon goes to a 4ft southerly with an onshore wind, making it ordinary.

From Thursday the 16th through Sunday the 19th, we hit a flat spell. The swell drops under 3ft, and the energy falls below 300. There are some glassy moments, but the waves are too small to get excited about. Sunday the 19th afternoon shows a glimmer of hope with a 4ft SW swell and 497 energy, but it’s a wait-and-see.

Now, the real standout of the entire forecast is the final week. Monday the 20th kicks off a run of pumping swell. That morning we have 4ft SW with 705 energy and glassy WNW wind. Tuesday the 21st is the absolute highlight: the morning is 5ft SW from a very long 18 second period, with 1994 energy and dead calm. That’s an incredible groundswell, and with the reef at Black Rocks Jetty, it’s going to be a thing of beauty. The afternoon pushes even bigger to 7ft and 2425 energy, still glassy. This is expert territory.

Wednesday the 22nd is still big at 7ft, but a cross-on wind makes it less clean. The afternoon recovers to 6ft and glassy, so pick that window. Thursday the 23rd is magic again: the morning has 4ft with a 16 second period and 1114 energy, glassy. The afternoon is the real kicker: 5ft from the SSW with a mind-bending 23 second period, generating 3513 energy and clean offshore NE wind. That’s a very long period groundswell – perfect for this reef.

Friday the 24th is the biggest day of the forecast. The morning is a solid 10ft SSW swell with a 17 second period and a massive 5270 energy, and it’s glassy. This is only for the experts, and it’s going to be exceptional. The afternoon is still huge at 8ft with 4128 energy, still glassy. Then Saturday the 25th fades fast, with a bumpy 6ft and cross-on wind, so the party is over.

So, the call is simple: the first week has a few good windows, but the second week from Monday the 21st through Friday the 24th is the true standout. That Tuesday the 21st morning and Thursday the 23rd afternoon are the absolute best on offer, with clean, long-period groundswell and perfect winds. Don’t sleep on it.

Rusty.
