The Lowdown
G’day, Rusty here. Let’s break down the next couple of weeks at Turtle Cove. It’s a slow start, no doubt. For a reef and point that’s fairly consistent, the first week is mostly flat, windy, and wet. There’s a decent pulse in the second week, but you’ll need to be patient.
Water temp is about 67°F – a bit colder than usual for this time of year, so a wetsuit is a good call.
Tuesday the 14th kicks off with a tiny 1ft SE swell and a strong southwesterly blowing 28 mph. That’s a write-off.
Wednesday the 15th is the first real option. Morning has a 4ft SW swell, 6-second period, and a clean offshore wind from the west at 12 mph. Combined energy is moderate (148). It’s small but clean. Afternoon holds a similar 4ft SW swell, still offshore. Best of the first week – fine for an intermediate on a longer board.
Thursday the 16th drops to 2ft and cross-off winds. Friday the 17th is glassy but only 2ft – too small. Saturday the 18th is glassy at 2ft, then onshore winds blow Sunday and Monday. The 19th and 20th see some S swell up to 5ft, but it’s onshore or cross-on, with moderate energy (272-310). Not clean.
The standout is Wednesday the 22nd morning. A 7ft S swell, 9-second period, with a fresh offshore wind from the west at 18 mph. Combined energy is strong (766). That’s proper groundswell, clean, and the swell direction (S) is a good match for the optimum SE. It’s for experienced surfers only – over 8ft is expert territory, and 7ft is borderline big for beginners. The period is just under 11 seconds, so it won’t be too straight for this reef and point.
Thursday the 23rd drops to 3ft. Friday the 24th through Sunday the 27th is a flat spell – mostly 2-3ft, with onshore or cross-off winds. Not much.
Tuesday the 28th afternoon shows a 5ft SSW swell, 7-second period, with offshore wind from the WSW at 12 mph. Combined energy is moderate (235) and the forecast says “expect good surf conditions.” It’s smaller than the 22nd, but clean and rideable. Wednesday the 29th has 3ft offshore winds, but small.
The absolute best is Wednesday the 22nd morning at Turtle Cove. That’s the one to mark on the calendar. Crowds are listed as “sometimes” – on a good day like the 22nd, expect a few others out.
Rusty.

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