The Lowdown
Hey crew, Rusty here with a look at the Banzai forecast. It’s a pretty bleak picture for the next couple of weeks, so don’t get your hopes up.
Things start on Saturday, August 8th, and it’s already a bust. Onshore SE wind at 16 mph, a tiny 3 ft swell from the SE with a short 6-second period, and the wave energy is weak at 73. Just poor conditions all around.
That same story holds through Sunday, Monday, and into the middle of the week. The wind stays onshore or cross-onshore, the swell stays small and weak, and it’s just consistently rated as poor.
We do see a jump in size towards the end of the first week. By Thursday, August 13th afternoon, the swell is up to 5 ft from the SE with a 7-second period, and the energy hits a moderate 261. But the wind is still onshore at 16 mph, so it’s going to be choppy and messy.
The biggest waves of the whole forecast hit on the weekend of August 15th and 16th. On Saturday the 15th, we’re looking at 7 ft from the ESE with a 10-second period and strong energy of 830. By the afternoon, it’s 8 ft from the ESE with a 12-second period, and very strong energy at 2013. That’s a solid groundswell. But again, the wind is cross-onshore from the E at 16 mph. That size is for experts only, and with the onshore wind, it’s gonna be a battle. The direction is also off from the optimum S swell Banzai prefers.
After that big pulse, it drops off fast. Monday the 17th is small again. Tuesday the 18th morning gives us the only slight glimmer of hope – a cross-shore wind from the ENE at 9 mph, with a 6 ft swell from the SE and moderate energy of 589. The report calls it “marginal,” scoring a 2 out of 10. It’s the best it gets, and that’s not saying much. The afternoon gets bigger at 7 ft, but the wind turns cross-onshore and it’s back to a score of 1 out of 10.
From Wednesday the 19th through the end of the period on Sunday, August 23rd, it’s back to small, weak, onshore slop. Swells are mostly under 3 ft, periods are short, and energy is often below 100.
The only real window? That Tuesday morning, August 18th. The cross-shore wind and 6 ft swell is the only time things are even close to rideable. But it’s still just marginal. This is a rough stretch for Banzai. The water temp is about 85°, normal for this time of year, so at least it’ll be warm while you’re waiting for something clean to come through. Hang tight.
Rusty.

Information about the Banzai Surf forecast
The above surf forecast table for Banzai provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Banzai can be found by selecting the local surf guide option on the grey menu. Our Banzai surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Banzai) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Banzai may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
Banzai is 2 km (1 miles) from the city of Boca Chica. If you plan a holiday in Caribbean Coast - Dominican Republic, look for hotels and other accommodation in Boca Chica. Boca Chica has rooms for a wide range of budgets as well as car hire and transport links.
