The Lowdown

Alright folks, Rusty here. Let’s talk about the next couple of weeks on the water. The swell window is open for a specific spot, and it’s all about picking the right sessions. We’ve got a nice, consistent run of clean, offshore conditions coming up, but the size is on the smaller side, so temper your expectations. There’s a real standout window right in the middle of the period that’s worth circling on the calendar.

We’re looking at The Cove, a reef break that’s always an advanced proposition. It’s inconsistent, which means when it’s on, it’s on, but you’ve got to be patient. The water temp is sitting at 80°, which is exactly average for this time of year, so no surprises there.

The action starts Monday, the 31st of August, with a small 2ft swell from the SW, but with a super long 15-second period. That’s proper groundswell energy, and with a light offshore breeze from the NE, it’ll be clean. The combined energy is moderate at 299. It’s a gentle start. Tuesday the 1st through Wednesday the 2nd of September sees a little more juice, with the swell pushing to 3ft from the S/SSW, still with long periods (16-18 seconds). The wind stays light offshore, keeping it glassy. The energy picks up to a solid moderate range (485 to 592). This is good, clean surfing.

Then we hit the real gem. Friday the 4th of September is the standout. The swell jumps to 5ft from the S, with an 11-second period. The wind is a gentle offshore breeze from the NE. The wave energy is strong at 522. This is the best size and quality combo of the whole outlook. Saturday the 5th is also a treat, with a glassy morning—wind is dead calm from the SW at 0 mph. The swell is 3ft from the SSW. That’s as clean as it gets.

From Sunday the 6th into the second week, the swell hangs around the 2ft to 3ft range, but the period stays long, and the wind is mostly offshore or glassy. There are a couple of days to dodge, like Tuesday the 8th of September when a cross-onshore wind messes up the early session, but the afternoon goes glassy again. The 9th of September is another glassy morning, with a 3ft SSW swell and 14-second period. Mid-September, the 13th and 14th, offers some clean glassy mornings with 2-2ft SW/SSW swells, but the energy is lower.

The overall vibe is a slow-burn classic. The Cove is not a beginner spot, especially with those long-period swells that can make a reef break a bit more critical. The crowds are possible, given it’s a known spot, but the inconsistency might keep the lineup thin. The 4th of September is your best bet—biggest swell, cleanest wind, and the most energy. Don’t sleep on the glassy mornings of the 5th and 9th either.

Information about the The Cove Surf forecast

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