The Lowdown
Hey, Rusty here. Turtle Cove is in a funk, plain and simple. We’ve got one spot on the list: Turtle Cove, a reef and point that needs swell from the ESE, S, or SSE, but the 16-day outlook is mostly flat and messy. There’s a big gap from now until Thursday the 30th of July with nothing worth paddling out for—just onshore wind and tiny waves.
Thursday the 30th finally shows a pulse. That morning brings a SSE swell at 3ft with a 10-second period—decent groundswell, and combined energy is moderate (216). Water temp is a bit colder than normal at 67°, and the wind is light easterly and glassy, so clean. Still, the surf is marginal. Best bet is Thursday afternoon: swell same direction, bumps to 4ft, period still 10 seconds, and energy jumps to 323. Wind is a light north cross-shore—good for a reef and point. This could be rideable, but not a standout.
Friday the 31st is back to onshore chop, S swell at 3ft and short period (8 seconds). Saturday the 1st of August is tiny—2ft and cross-shore wind. Skip it.
The real highlight, if you can call it that, is Tuesday the 4th of August morning. South swell at 3ft, 8-second period, combined energy 115 (weak-to-moderate). Wind is glassy from the NW—clean, clean, clean. Water temp is average. Crowds are possible here. That afternoon also cleans up with cross-offshore wind from the SSW at 9 mph, but swell drops to 3ft. Surfable but ordinary.
After that, it fades. Wednesday the 5th is choppy-small. Thursday the 6th is flat—0.7ft and clean but tiny. Friday the 7th has clean cross-offshore wind and a SSW swell at 3ft, but only a 6-second period (weak energy, 71). Saturday the 8th of August shows 5ft to 6ft from the SSW, period still 6 seconds, energy up to 192–240 (moderate). Wind Saturday morning is east onshore and unknown, so likely messy. Over 5ft is expert territory at a short-period break, and it might be better for kite surfing than paddle surfing.
No true standouts here. The only two windows are Thursday the 30th afternoon and Tuesday the 4th of August morning. It’s a dry spell, but forecasts can change. 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.
