The Lowdown
Alright, Rusty here again for the Banzai (Hawaii) stretch.
Looking at the whole 16-day window, it’s a tough one. The finder is basically showing a big fat zero for the first two weeks. We’ve got a long gap of nothing but onshore wind and weak, choppy conditions. The first real glimmer of anything doesn’t show up until Monday afternoon, August 17th, and even then it’s just a marginal call.
The main issue is the wind. It’s consistently from the SE or ESE, which is onshore or cross-onshore for Banzai, and that’s been trashing the surf quality. The swell is small and weak, coming from the SE, which is the opposite of what this place wants to see. The swell period is short, mostly 6-8 seconds, so there’s no real energy in the water. The combined energy is weak, usually under 200 (like 91 to 150), which tells you the ocean is just flat and messy.
The only day that’s worth a mention is Monday, August 17th, in the afternoon. We finally see a bit of a pulse, with the swell bumping up to 6 ft from the ESE, with a period of 8 seconds. The combined energy jumps to 682, which is a moderate energy level. But even then, the wind is still onshore from the ESE at 9 mph, and it’s a risk of thunderstorms. It’s *marginal* at best, but it’s the only thing on the entire board. That’s your best bet if you’re desperate, but don’t expect much.
Water temp is a warm 85°F with a tiny anomaly of 2°F, so it’s about average for the time of year – no surprises there.
In short, it’s a bleak run. Banzai needs a clean S swell and offshore NW winds to really fire, and we’re getting none of that. The first 14 days are a write-off. The 17th offers a tiny chance, but it’s a long shot. Hang in there, the forecasts can change.
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.
