The Lowdown
Alright folks, Rusty here. Gotta be straight with you – the next 16 days at Banzai are a tough pill to swallow. We’re looking at a long, long stretch of poor surf conditions with no real standouts on the horizon. The water’s sitting at a warm 85°, which is about average for this time of year, but that’s about the only thing that’s standard.
The pattern starts off messy. Monday the 10th through Thursday the 14th, we’ve got a mix of onshore and cross-onshore winds, mostly from the ESE and SE, kicking up chop and keeping things blown out. Swell sizes are all over the place, from a tiny 3 ft up to 5 ft, but the periods are short – 6 to 7 seconds – so there’s no real push or shape to the waves. The combined energy is weak to moderate (54 to 250), and it’s all just poor surf.
Then Friday the 14th morning, we see a larger pulse of swell hit 7 ft from the ESE, but it’s still just a short period groundswell (8 seconds) with a moderate cross-onshore wind. The energy jumps up to 943, which is strong, but with the wind state reading “moderate cross-onshore and choppy,” it’s a classic case of a lot of energy and no quality. That’s a big, crumbly mess for experts only, and it’s still a no-go. The weekend of the 15th and 16th sees a bit more size, around 6 ft to 6 ft, with periods stretching to 9-10 seconds, but again, the wind is onshore, and the wave comment is consistently “poor surf conditions.”
After that, from the 17th onward, the swell drops right off, with heights under 3 ft and very weak energy (21 to 76). The wind remains onshore from the SE, so even the tiny waves are messy. The entire forecast is a washout. There’s not a single session in the 16-day window that’s worth paddling out for. The reef is getting no love from the swell direction, and the wind just won’t play nice.
For a spot like Banzai, which is fairly consistent and exposed, this is a rare blank run. It’s the kind of stretch where you just wait for the next system to roll in. Keep an eye on the forecasts, because it tends not to stay this poor for long.
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.
