The Lowdown
Alright, Rusty here again, this time in feet and miles per hour.
Let’s break down Bay Front for the next couple weeks. It’s a reef break, and it rarely breaks, so we’re starting with a long dry spell. From Saturday afternoon, August 8th, through to Friday, August 21st, the surf is mostly poor to marginal. The wind is cross or cross-onshore, making the surface choppy, and the swell is small – around 3 to 6 feet from the east, with a period of 8 seconds. That’s weak, short-period windswell with combined energy between 200 and 400 – just not worth getting wet for.
There’s a brief moment on Sunday, August 16th, when the wind goes strong offshore from the south at 25 to 30 mph. The surf will be clean, but look at the size: 7 to 8 feet of east swell with an 8-second period. Combined energy hits 1861 and 740 – that’s a lot of power, but it’s short-period and dumpy. This is expert-only territory, and even then, paddle-out will be a mission. Not the best shape.
The pick of the bunch is Saturday, August 22nd. Morning and afternoon both look solid. Swell is 5 feet from the east with a 9-second period – a bit longer, so the waves will have some shape and push. Wind is light from the east-southeast at 6 to 10 mph, cross-offshore, so the surface is clean. Combined energy is 386 and 356, moderate but fun. Crowds are listed as “sometimes,” so you might bump into a couple other surfers, but it won’t be packed. Swell direction is close to the optimum northeast, so the reef should work nicely. This is the best window – not giant, but clean, fun waves for intermediate surfers.
Water temp is about 80°F, just a touch warmer than average for the season.
After that, Sunday August 23rd fades back to cross-shore winds and marginal conditions. So if you’re looking for a session, target that Saturday, August 22nd. The rest is a wait-and-see.
Rusty.

Information about the Bay Front Surf forecast
The above surf forecast table for Bay Front provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Bay Front can be found by selecting the local surf guide option on the grey menu. Our Bay Front 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 (Bay Front) 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 Bay Front 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.
Bay Front is 1 km (1 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.
