The Lowdown
Alright folks, let’s cut to the chase. The next two weeks look flat and uninviting, nothing to get the heart racing.
Our only real chance for a wave is on Friday. The swell is a small 3ft from the southwest at Suicide Cliffs (Big Island). It’s not big, but the cross-off breeze will make it look clean. The energy is weak, and the water is about normal for this time of year. It’s a maybe.
Saturday is a step down. The bump from the southeast wind just makes it messy. Sunday through Tuesday, the trade wind kicks up and chops everything to bits. There's a brief pulse of east swell on Tuesday afternoon that pushes to 5ft, but it’s short-period junk from the wrong angle. It’ll be a washing machine.
By Wednesday, the swell just dies. We’re talking ankle-biters at best. The week after that has a few pulses of south swell, but they’re small and the winds are mostly onshore or cross. There’s a cleaner moment on Sunday the 23rd, but the waves are only 2-3ft. Not worth the drive.
Honestly, the only time with a clean wave is Friday. The rest is a long stretch of nothing. It’s a dry spell, plain and simple. For a reef break like Suicide Cliffs, we need a proper SW groundswell to light it up, and that just isn’t happening. The long-range stuff holds some promise, but it’s too far out to get excited about.
Keep your board in the car, but don’t be surprised if you don’t use it.
Rusty out.

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