The Lowdown

Wednesday morning starts off clean with a light N offshore breeze, but there's no real juice in the water—only a tiny 1ft S swell at 7 seconds, weak combined energy (28). It's flat and small, not worth getting wet for more than a splash. Thursday stays small, 1ft, glassy in the afternoon, still nothing doing. Friday sees some bump from an ESE cross-onshore, but the swell jumps a bit to 3ft at 6 seconds, choppy with a risk of thunderstorms—not inviting. Saturday morning brings a slightly better 4ft SE swell, but it's cross-shore and messy, with only moderate energy (140). Sunday cleans up a bit with a cross-offshore ENE wind and 4ft E swell, but it's still short-period and weak (125). Monday and Tuesday are small and clean, but no power. By Wednesday the 16th, a longer-period SW swell (11s) shows up at 2ft, but onshore wind makes it a write-off.

So, the first week is a dud. There's a real gap from now until the 20th—over a week of small, weak surf. But then things get interesting.

Sunday the 20th morning gives us our first real standout: a clean cross-offshore ENE breeze, 4ft of SE swell with a long period of 16 seconds—that's proper groundswell. The combined energy jumps to 539, which is decent, and the wave comment says expect very good surf conditions. Suicide Cliffs (Big Island) is a reef, exposed to SW, but this SE swell is coming in good. It's a little inconsistent for a reef, but when it hits, it'll have some push. Light wind, clean lines—this is the first day I'd get excited about.

Then Monday the 21st morning is even bigger: 10ft SE swell at 14 seconds, energy jumps to 3599—that's strong. Still clean with ENE cross-offshore wind, and it's excellent for experienced surfers. This is getting serious, but 10ft on a reef is no joke. Tuesday the 22nd is the biggest of the run—16ft at 16 seconds in the morning, energy 12002, and then 20ft in the afternoon with energy 17316. That's enormous. The wind and tide are favorable, but honestly, it's predicted to be too big for this break by then—only for the most hardcore, and even then, it's pushing limits. Wednesday the 23rd drops to flat, and from Thursday the 24th it's all blown out by a strong ENE wind with a short-period NW swell, so that's done.

So, the best on offer is Sunday the 20th morning—clean, solid, manageable size and proper period. Monday the 21st morning is a close second for those who want bigger, but it's already on the heavy side. Beyond that, it's a huge, humbling swell that suits tow-surfing or just watching.

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.

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.
