The Lowdown
G’day, it’s Rusty here. Look, I’m going to level with you straight off the bat: the next couple of weeks are looking pretty grim for a paddle. We’ve got Bay Street (Big Island) on the radar, and it’s a real mixed bag at best. The water’s sitting at 72.1°, which is much warmer than normal for this time of year, so if you’re getting in, you won’t need much rubber.
Right now, into Saturday the 5th, there’s a bit of life in the water with a 3ft SSW swell rolling in at a solid 16 seconds. The energy is moderate at 602, but the wind is a cross-on and the call is “marginal” – a bit of a tease, really. We see that same swell hanging around for the rest of the weekend, dropping slightly to 2.5ft, but the winds are cross or onshore, keeping things a little soft. Sunday afternoon might offer the best chance with 3.5ft of S swell, but it’s still not clean.
Into Monday the 7th, the swell drops a touch to 2.5ft, but the wind goes light and offshore from the SW in the morning. That’s the best window of the whole run for a wave that’s actually got some shape to it. The period’s still a decent 14 seconds, and the energy is moderate at 515. If you’re desperate, that Monday morning paddle is your best bet. The rest of that week sees the swell hover around the 1.5ft to 3ft mark, but the winds are mostly onshore or cross-onshore. The period starts to drop and bounce around – down to 10 seconds by Wednesday the 9th, which makes things feel weaker.
By the time we get to the second week, it’s a write-off for surfing. From about Tuesday the 15th through to Thursday the 17th, the swell is tiny, around 1.5ft, with long periods – that’s just not enough oomph to break properly. You’d be wasting your time. We do see a bit of a nudge from Friday the 18th, with the swell struggling to 1.5ft-2ft and the period stretching out to 19 seconds, but the energy is still on the weaker side and there’s no clean wind to help it out. On Sunday the 20th, the swell pushes up to 2ft and energy climbs to 411, but it’s still a weak, messy offering. Given the persistent cross-onshore wind and small, gutless surf, this setup honestly looks more interesting for a kite surfer than anyone on a paddleboard.
Basically, if you’ve got to get wet, make it Monday morning. Otherwise, you’re waiting for better days.

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