The Lowdown
Alright, Rusty here. It’s a slow stretch ahead at Suicide Cliffs. Not much going on, but there’s a couple of days that might get you out of the house. Water temp is 84°, right around normal for this time of year.
First window worth a look is Thursday the 13th. You’ve got a clean 4ft SW groundswell with a 8-second period, and the morning’s glassy with a light north wind offshore. The combined swell energy is moderate at 312. It’s small, but it’s clean. Thursday afternoon stays tidy too, with a 3ft SW windswell and a light cross-offshore breeze. Energy drops to 220, but the surface is smooth.
Friday the 14th bumps up a bit—4ft SSW in the morning, 4ft SW in the afternoon—but the wind is a moderate cross-offshore both times, keeping it clean. Energy is moderate (252 and 251). Still short period, so not a lot of grunt.
Saturday the 15th is the other clean day: 4ft SW in the morning, 4ft SW in the afternoon, with light cross-offshore winds. Morning energy is 281, afternoon 313. Clean, small, and predictable.
From Sunday the 16th, it’s a mess. Winds go onshore or cross-shore, and conditions get choppy and lumpy. The swell fades to 2–3ft by the 19th with poor wind. Around the 21st the swell tries to come back to 4–5ft, but it’s all onshore from the SE or ESE, so it’s choppy. Energy hits 312 that afternoon, but the wind kills it. After the 24th, winds are strong—22–25 mph—and the swell is tiny, so it’s more of a kiteboarding window than a surfing one.
Best bet is Thursday the 13th or Saturday the 15th. Otherwise, it’s a long dry spell. Forecasts change, so don’t write it off completely.
Rusty.

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.
