The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for the next couple of weeks.
Honestly, it’s a pretty quiet stretch for the Banyans. The surf is going to be small and unimpressive for the vast majority of the forecast period. We’re looking at a long, drawn-out run of knee-high slop and weak, wind-affected lines. Don’t get your hopes up for any big scores; this is a time for patience.
The first few days are a real struggle. Tuesday morning the 4th of August starts with a tiny 2ft swell from the SSW, but with a light onshore breeze, it’s just poor. The energy is weak at 115 (combined energy) and the conditions are messy. The wind flicks around but never really cleans it up properly. Wednesday and Thursday are even smaller, with swell dropping to 1.0ft – 1ft. Thursday afternoon the 6th does offer a brief moment of relief with glassy conditions and a 1ft SSW swell, but it’s barely surfable and scored as “surfable waves but very ordinary conditions.” Not exactly a day to call in sick.
We drift through a long featureless stretch. Friday the 7th and Saturday the 8th have a bit more period, with a 20-second groundswell showing on Friday afternoon, but it’s only 1ft from the SW with a cross-on breeze. The energy hits 175 (combined energy), but with the wind and size, it’s a frustrating tease. The real story is a long period, long period swell hitting a reef break – it’ll likely be too straight and walled up to be fun anyway.
The only session that makes me want to paddle out is the morning of Friday the 14th of August. The wind goes glassy, the swell is a clean 2ft from the WNW with a nice 17-second period, and the wave energy is up to 375 (combined energy). It’s the only time the forecast calls for “good surf conditions” in the whole 16-day window. The coral reef will be working, and those long, clean lines will be a welcome sight after the drought. It’s the single standout. The water temp is about average for this time of year. The Banyans can be a crowded spot, so keep an eye out for the usual suspects.
The weekend after that, the 15th and 16th, sees a bit more size (3ft) but the wind is messy again – cross-shore or cross-on. The energy is high, but the quality just isn’t there. The final week of the forecast is more of the same: small, weak swells, mostly onshore or cross-onshore winds, and poor to marginal conditions. It’s a bleak run.
So, mark your calendar for the morning of the 14th. That’s your best bet. Otherwise, wax the longboard and wait for the next pulse.
Rusty.

Information about the Banyans Surf forecast
The above surf forecast table for Banyans provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Banyans can be found by selecting the local surf guide option on the grey menu. Our Banyans 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 (Banyans) 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 Banyans 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.
Banyans is 94 km (58 miles) from Hilo. If you plan a vacation in Big Island, look for hotels and other accommodation in Hilo. Hilo has rooms for a wide range of budgets as well as car hire and transport links.
