Hey crew, Rusty checking in. I've got to level with you about Banzai – the outlook for the next couple of weeks is a total bust. We're looking at a solid run of nothing worthwhile, with no clean surf anywhere in the 16-day forecast.
Straight up, the winds are the killer. They're pinned out of the east and southeast, blowing cross-onshore or straight onshore for almost every single session. That's shredding any chance of a smooth wave. And the swell direction is all wrong, too. Coming from the SE and ESE, it's the exact opposite of what Banzai (Oʻahu) needs to work its magic – that spot craves a southwest groundswell.
Water temp is around 84°F, which is pretty standard for this time of year, so no weird anomalies to blame.
Here's the ugly timeline. It starts on Sunday the 5th with a weak 3 to 4ft swell from the SE, a short 8-second period, and terrible energy – a combined 119, which is weak. The wind is already trashing it. From Monday the 6th all the way through Wednesday the 16th, it's just a blur of onshore slop. Swell heights bounce between 3 and 6ft, but with that constant ESE wind, it's all messy whitewater. You'll see some higher energy numbers pop up, like 550 on Monday the 6th or 770 on Saturday the 11th (which is moderate to strong), but it's completely wasted by the wind.
The only time the charts even hint at "marginal" is for Tuesday morning the 7th and again on Sunday morning the 19th. That's a brutal 11-day gap with nothing. That Sunday the 19th does have a bit more energy (580, moderate) with a 6ft swell from the ESE and just a light breeze. It's still cross-onshore, so you'll be fighting the chop. That's the absolute best this two-week stretch has to offer, and it's still just average.
Bottom line: don't bother. This is a classic summer flat spell for Banzai. The wind is wrong, the swell is wrong, and there's no light at the end of the tunnel. Stash the board and find something else to do until the weather pattern decides to shift.
Stay salty.

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.
