The Lowdown
Alright, surfers, Rusty here. Let’s have a look at what’s coming up for Bay Front.
This is a tough one to start. The first two weeks are pretty much a write-off for getting any decent waves. We’ve got a bit of a wait on our hands. The first real glimmer of hope doesn’t show up until the tail end of the third week.
Let’s be straight with you: there’s nothing worth paddling out for this weekend or next week. The wind is messy, often cross-onshore, and the swell is either too small or just plain ugly. The combined energy is weak, sitting in the low hundreds (e.g., 139 on the 21st). It’s a frustrating start.
The real story begins to shift around the 26th of August. Swell starts to show up with some serious length, with periods hitting 18 seconds. That’s proper groundswell. The energy jumps massively, hitting 730 early on the 26th, and climbing to 1314 by the afternoon. That’s a big jump, but it’s still a bit of a gamble. The wind is a light cross-onshore breeze, so it’s not going to be perfect, but it’s a lot better than what we’ve been dealing with.
The standout period, and I mean the only one worth circling on your calendar, is the 27th and 28th of August. We’re looking at a solid 6ft swell from the east with a long, long period of 17-18 seconds. The combined energy is strong, sitting between 2000 and 2361. That’s real power. The wind is light and cross-shore, which at this reef break should mean clean, lined-up waves. This is a reef break, so that long period groundswell is going to wrap in nicely. The waves will be well-shaped, with plenty of energy. The water temperature is a normal 81°F for the time of year, so a rashie is plenty.
For the crew who can handle it, this is the best on offer. The swell is over 5ft, so beginners might find it a bit much, but for intermediate and above, it’s game on. Keep in mind this is a spot that *rarely breaks*, so when it’s on, it’s a special occasion. The crowds are listed as *sometimes* there, so expect a few others who’ve been waiting for the same window.
The weekend of the 29th and 30th still has some size, but the period drops off a bit and the wind gets more cross-onshore, so it’s not as clean. The energy is still high (around 1500-1800), but the quality won’t match the 27th and 28th.
So, to sum it up: the first two weeks are a bust. The 27th and 28th of August are your best bet by a long shot. That’s the one to go for. After that, it’s still surfable but a step down.
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.
