Alright, this is Rusty. Let’s break down what’s heading to Cunns.
First off, the water temp is about 61°F right now, which is dead average for the season. No surprises there.
The forecast kicks off Sunday the 5th with a solid push of SW groundswell – about 6 feet at a very long 16-second period. The combined energy is strong, sitting at 1631. Winds are a gentle cross-off from the ENE, perfect for this reef. For the experienced crew, this is the standout of the first week. The swell direction is spot-on for Cunns, but remember, this break is *inconsistent* – don’t expect a wave every few minutes. That long period will mean long lulls between sets, but when they come, they’ll be proper.
Monday the 6th drops way down to around 4 feet, cleaner in the afternoon with a light offshore from the ESE. It’s rideable, but nothing special – energy drops to 390. Tuesday the 7th is the same story: small, clean, mid-length period.
The real good stuff returns Wednesday the 8th. Morning has 5 feet of groundswell out of the SW at a thumping 17 seconds. Energy is strong again at 1573. Winds are a gentle cross-off from the NE. This is a top call for advanced surfers – *excellent* shape on the menu. The afternoon holds similar size and a 16-second period, still clean. Wednesday is your ticket.
Thursday the 9th and Friday the 10th go south fast – onshore winds and a fresh breeze chop everything up. Saturday the 11th and Sunday the 12th are blown out completely: near gale-force winds, rain, and 8-to-10-foot slop. Do not paddle out. That’s kite-surfing weather, not paddle surfing.
Monday the 13th stays ugly with 10-foot plus and a strong cross-shore.
Then it cleans right up. Tuesday the 14th is stunning: 5 feet from the SW, light clean cross-off wind from the SSE, and a 19-second period in the afternoon pushing energy to 1339. Glassy, powerful, and clean. Wednesday the 15th is nearly a carbon copy: 5 feet, light winds, pristine conditions. These two days are your second-week highlights.
After that, it gets marginal again from Thursday the 16th onward, with onshore winds and lumpy surf. The 20th has a very long 21-second period swell, but it’s only 2 feet and the wind is messy, so it’s a tease.
In short: Get on it Wednesday the 8th, then wait through a rough patch for the magic on Tuesday and Wednesday the 14th and 15th.
Rusty.

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