The Lowdown
G’day, Rusty here. To be straight with you, this outlook for Banzai (Hawaii) is a tough one. We’ve got a full 16-day window ahead, but it’s a barren run for paddle surfing. There isn’t a single decent recommendation in the mix, so don’t bother waxing up your board just yet.
The pattern is persistent onshore wind – mostly from the ESE and SE – blowing at 12 to 16 mph, so it’s messy and chopped up. Thursday the 30th of July kicks it off with clear skies but a moderate breeze straight onshore, making the 4.3 ft swell pretty unrideable. That sets the tone. Friday the 31st is more of the same, with a cross-on breeze that’s just adding chop to the 3.9 ft swell. Saturday the 1st of August sees a spike in combined energy to 365 (moderate wave energy), but that’s still pinned to an onshore wind and poor surf conditions. No joy.
The entire first week is a write-off. By Monday the 3rd of August, we’ve got a risk of thunderstorms with the onshore flow. The second week doesn’t offer any relief. From the 4th to the 12th of August, it’s a monotonous run of 3.3 ft to 4.3 ft swell, always coming from the SE with short periods of 6 to 8 seconds, and always blown out by an onshore or cross-onshore breeze. The combined energy drops as low as 78 (weak wave energy) on the morning of the 10th of August.
There’s a slight lift in size on Thursday the 13th of August, with the swell hitting 5.6 ft from the ESE and the combined energy jumping to 601 (strong wave energy). Even then, it’s cross-onshore and choppy, so the power just means bigger, messier lumps. For kite surfers, that’s a different story – the consistent onshore wind and moderate swell might be worth a look, but for a paddle surfer, it’s a pass.

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.
