Marengo Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s have a look at what’s cookin’ for Marengo over the next couple of weeks.

We’ve got a bit of a slow start, but hold onto your boards because things are going to get real interesting. The first solid session kicks off Friday 7th August. Marengo is a reef and point break, fairly exposed to the swell, and it’s got a bit of a beginner-friendly vibe when conditions are right.

Friday 7th August is where you wanna be. Morning sees a clean 5 ft SW swell (16-second period) with a light NW cross-off breeze. The combined energy is strong at 1105, and it’s delivering very good surf. The water temp is about average for this time of year, so a spring suit should do. Then Friday afternoon turns glassy – 4 ft of SW groundswell with zero wind. That’s proper clean, face-high waves with a lot of push. This is the standout of the whole run.

Saturday 8th gets messy. The swell holds around 4 ft, but a howling 12 mph N cross wind chops it up. Not worth paddling out. Sunday 9th is even worse – rain, onshore wind, and the swell drops to under 3 ft. Give it a miss.

Monday 10th sees a jump in size – 6 ft SW swell, but the wind is a strong 22 mph cross-off. It’s clean, but that wind is fresh. The energy is moderate to strong (2402), but conditions are marginal. Only for the keen.

Tuesday 11th is cleaner but the swell is dropping. 5 ft in the morning, then fading to 4 ft by afternoon. Still, a clean wave is a clean wave.

Wednesday 12th is when it gets serious. Morning brings 8 ft SW swell (16 seconds) and a solid 19 mph cross-off. That’s big, powerful energy at 4987. On the afternoon, it jumps to 10 ft with a 25 mph offshore wind. That’s a strong offshore, clean but hard to paddle into. This is expert territory.

Thursday 13th is the big one. 20 ft of SW groundswell in the morning. That’s a massive 20694 combined energy. The wind is offshore, but the forecast says it’s too big for this break. This is a day for watching, not paddling. Afternoon drops to 16 ft, still huge. Only absolute legends should even look at it.

Friday 14th is the reward for the brave. The swell drops to a still-solid 8 ft, with a 12 mph offshore. The wind is moderate offshore, the waves are clean, and the energy is strong (3882). This is excellent, powerful surf for experienced surfers. Crowds are possible, but it’s a lot of water.

Saturday 15th the swell backs off a bit to 7 ft, but the wind turns light cross. It’s clean enough, but a bit jumbled. Sunday 16th drops further to 4 ft with a light cross-onshore. Not great.

Monday 17th morning is glassy – 3 ft of SW swell, no wind. That’s a nice, clean, small wave for a longboard or a funboard. Tuesday 18th is even better for the glassy conditions – dead calm, 3 ft swell. Perfect for a quiet session.

Wednesday 19th afternoon sees a nice little spike: 4 ft of WSW swell with a 6 mph offshore. Very clean, good energy (1021), and a long 18-second period. That’s a quality wave.

Thursday 20th gets windy again, but there’s still 5 ft of clean swell. Friday 21st has a morning of short-period, cross-shore junk, but the afternoon turns it on: 6 ft of SW swell with a clean cross-off. That’s excellent for experienced surfers.

Saturday 22nd finishes the run with glassy conditions – 4 ft of SSW groundswell, a light 3 mph offshore, and clean. A nice way to end.

So, the best on offer? Easy. Friday 7th August for the glassy, clean, chest-to-head-high waves. And for the big guns, Friday 14th August is the one – powerful, offshore, and demanding respect.

Rusty.
