The Lowdown

Alright folks, Rusty here. Let’s be straight with you – this stretch of the forecast is a tough one. We’re looking at Big Wave Bay, and honestly, for the next three weeks, there’s almost nothing to get excited about. The waves are tiny, the wind is messy, and the consistency is just not there for a proper paddle session.

Looking at the first week, from Tuesday the 14th all the way through to the end of the week, it’s a write-off. We’re seeing a lot of stormy weather, cross-shore winds, and the swell is flat or barely a ripple. The combined wave energy is almost non-existent, with values like 2 or less. There’s a brief moment on Sunday the 19th morning where the wind goes glassy, but the swell is still only 0.3 ft – not enough to ride. Even the water temp is a warm 85°F, but that’s about average for the time of year, so no surprises there.

The gap continues. Monday the 20th is a mess with strong winds, and the rest of that week stays tiny. We’re looking at poor surf conditions, with cross-onshore winds chopping up what little ripple there is. It’s a long, quiet stretch.

You’ve got to wait until the very end of the forecast window for a glimmer. On Tuesday the 28th, we finally see a bit of life. The morning is glassy, with a tiny 0.7 ft swell from the ESE, and the combined energy climbs to 24 (weak). It’s not much, but it’s the cleanest we’ll see. The period is 14 seconds, which is a long-period groundswell, so it will have some shape, but it’s so small it’s only for the most patient soul on a longboard. Then on Wednesday the 29th, the swell bumps up to 1 ft, with a period of 14 seconds and energy hitting 92 (still weak). The wind is light cross-onshore, so it’s not perfect, but it’s the best we’ve got. By the afternoon, the swell lifts to 2 ft with energy at 120 (moderate), but the wind turns a bit more onshore.

For a beginner spot like this, anything over 2 ft is a session, but don’t expect any barrels. The optimum swell direction is NE, but we’re getting ESE, so it’s not ideal for this sheltered bay. The crowds are listed as “sometimes,” so when it’s this small, you’ll probably have it to yourself.

If you’re a kite surfer, the windy days in the first week might look interesting, but for a paddle surfer, this is a long dry spell. Keep an eye on the forecast, because it tends not to stay this poor for long, but for now, the 16-day window is a near-total blank.

Rusty.

Information about the Big Wave Bay Surf forecast

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