The Lowdown
Alright, let’s talk Saint Annes in feet and miles per hour. This is Rusty, and I’m telling you, it’s a tough 16 days. Water temp is about normal for the season.
The opening stretch, from Friday the 17th to Monday morning the 21st, is a bust. Waves are tiny—mostly 2 to 3 feet—with cross-on or onshore wind, light chop. The combined energy is weak to moderate, between 299 and 760 (moderate). Not worth paddling out.
Tuesday morning, the 21st, brings a pulse: swell hits 6 feet from the SSW, period of 12 seconds, with a combined energy of 1131 (strong). Wind is light and cross-on, so a bit bumpy but rideable. That’s the best of the first week. By afternoon it drops to 5 feet, so the morning window is key.
Then it’s back to small, choppy slop. Wednesday and Thursday the 23rd see 5 to 5 feet, but the period drops to 7 seconds (short period) and the wind is moderate and cross, making it a mess. Combined energy at 585 (moderate)—more for kite surfers.
The second week is a mixed bag. From the 24th to the 26th, waves are 2 to 4 feet, light cross-on winds, poor conditions. Sunday the 26th afternoon has a 4-foot SSW swell with strong energy of 1688, but it’s still cross-on and messy.
The real standout is Tuesday morning, July 28th. We’ve got a 4-foot SSW swell, period of 18 seconds (very long period groundswell), and combined energy of 1371 (strong). Wind is cross from the NW at 12 mph, so a bit of a cross-chop, but that long period will push powerful, fast lines into the reef. This is for experts only—over 5 feet and very long period. The morning is the window. The afternoon gets windier.
The 29th and 30th have small, cleanish conditions—on the 30th afternoon we get glassy 3-foot SSW swell with a period of 15 seconds, combined energy 491 (moderate). Clean but tiny. The 31st and 1st of August are back to poor, small waves.
So, your best bet is that Tuesday morning, July 28th. It’s not perfect, but it’s the only real chance at a decent wave. Crowds are often here, so expect company. The rest is a waiting game.
Rusty.

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