Marengo Surf Forecast and Surf Report

G’day, Rusty here. Let’s have a look at what’s on offer for Marengo over the next couple of weeks.

We’ve got a solid run of surf coming, but it’s not all smooth sailing. The first real pulse hits Thursday afternoon, and it’s a big one – a serious SW groundswell with 16ft faces and massive energy (12467). That’s a whole lot of water moving, and with a 14-second period, it’s packing plenty of punch. The wind is fresh offshore from the WSW, so the face will be clean, but at this size, it’s strictly for the experienced crew. Beginners, stay well clear; this is a heavy, powerful wave. The water temp is sitting at 58°, which is pretty much bang on for this time of year, so nothing unusual there.

Friday keeps the same energy, with another 16ft SW swell and a 15-second period in the morning, making it a very long-period groundswell. The wind stays offshore from the W, moderate to fresh, so the surface will be clean. This is still a big, powerful wave, and at a reef and point break like Marengo, that long period will wrap in nicely, offering some proper lines. Friday afternoon remains similar, just a touch more wind.

By Saturday morning, the swell starts to ease to 13ft, but it’s still a solid 13-second period. The energy is dropping (7569), but it’s still a hefty wave. The wind is a fresh offshore. Saturday afternoon drops to 12ft, still clean and offshore. This is the window where it starts to become a little more manageable for strong intermediate surfers, but it’s still a big, powerful ocean.

Sunday sees the swell ease further: 10ft in the morning with an 11-second period, and 5ft by the afternoon. The wind stays offshore, but the energy drops significantly (2733 then 566). The morning is still for experienced surfers, but the afternoon is where the conditions start to get good for a broader range of surfers.

Looking at the standouts, Thursday afternoon and Friday morning are the absolute standouts for the big wave chargers. The combination of a massive groundswell, long period, and clean offshore wind is about as good as it gets for a serious session. For the rest of us, Saturday afternoon and Sunday morning are the best bets, with the swell dropping to a more manageable size but still offering plenty of power.

Monday through to the middle of the next week sees a mixed bag. The swell drops to 4ft to 7ft, with periods bouncing between 10 and 16 seconds. The wind is variable, often cross-offshore, which keeps things clean enough. The standout in this stretch is Tuesday afternoon: a fresh offshore wind and a 7ft SW swell with a 15-second period, giving a clean, powerful wave. The energy is moderate (3296), so it’s a solid session for an experienced surfer.

The second week gets a bit more inconsistent. Around the 30th and 31st, the swell drops right down to 3ft to 5ft, with periods of 11-12 seconds. The wind is mostly light and offshore, which makes for clean, small waves. It’s not a standout, but it’s a chance to get a few cruisy ones.

Then, on the 1st of August, we get another big pulse. Saturday morning sees a 10ft SW swell with a 16-second period, but the wind is cross-shore, which will put some chop on the face. Saturday afternoon, though, is a gem: the same 10ft swell, 16-second period, but the wind swings to a light cross-offshore, delivering clean, powerful waves. This is a fantastic option for experienced surfers, and the energy is strong (4822). Sunday the 2nd holds similar quality, with 8ft to 7ft SW swell and light cross-offshore winds, making for some excellent, clean waves.

The very end of the outlook, around the 7th of August, sees a 5ft to 5ft SW swell with a very long 17-18 second period, but the wind is cross-shore and moderate, so it’ll be a bit messy. The energy is moderate (1639), but the conditions won’t be as clean.

Overall, the best on offer is Thursday afternoon and Friday morning for the big, clean, powerful groundswell. For a more manageable but still excellent session, Saturday afternoon and Sunday the 2nd of August are the picks. This is a run of solid surf, but it’s big; don’t be a hero if you’re not ready for it.

Rusty.
