The Lowdown
Alright folks, Rusty here. Let's be straight with you—this 16-day outlook for our region is a tough one to write. The whole stretch is a write-off for decent surf. From now through to August 17th, every single session is rated as poor. There's not a single standout window, not even a glimmer of a decent wave on offer.
The problem is the wind. It's almost locked in from the SE or ESE, blowing onshore or cross-onshore for the entire period. That's blowing straight into the face of any swell that tries to show up. We're looking at tiny, short-period windswell the whole time, mostly between 3 ft and 5 ft, with periods hanging around 6 to 8 seconds. The combined wave energy is weak, mostly under 200 (with a few moderate readings around 277-315 early on), but it's all messy, choppy, and blown out.
The optimum swell direction for Banzai (Big Island) is from the south, but with this persistent onshore flow, it doesn't matter. Even on the rare occasion of a slightly bigger swell on August 14th, hitting 7 ft from the ESE with a period of 9 seconds, the wind is howling onshore at 19 mph, making it a total mess. That's a strong, moderate energy day (646), but it's only for the hardcore. Water temp is sitting around 85°F, which is about average for this time of year, but you won't be enjoying it with those conditions.
To be honest, with this much consistent onshore wind and short-period chop, this setup looks more interesting for kite surfing than paddle surfing. Don't hold your breath for a change. Forecasts can shift, but right now, it's a full blank run. Put the board away for a fortnight.
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.
