Hey, Rusty here. Let’s break down Kellys Cove in feet and miles per hour for you.
The next couple of weeks are pretty grim, to be honest. The first week is a near-total washout. Winds are mostly cross-onshore or onshore, and the surf is choppy or poor. There’s some size – like the morning of Wednesday the 8th of July with 7ft from the NW – but that short 8-second period and cross-on breeze make it a mess. The combined energy is high (1419), but it doesn’t matter if the waves are junky.
The one bright spot – and I mean the only one – is the morning of Monday the 13th of July. The conditions go glassy with 4ft of WNW swell and a 9-second period. That’s clean, smooth, and surfable. Combined energy is moderate (382), but with zero wind, you’ll be stoked on whatever comes through. It’s an advanced spot, beach and reef, fairly consistent. Crowds are often, so expect a few locals, but for a glassy session, it’s worth the company.
Water temp is 62°F, which is much warmer than usual for this time of year – a big anomaly of 7°F, so you might not even need a full wetsuit.
After that Monday morning, it’s back to the same story: cross-on winds and rough conditions. A few glimmers in the second week – like Wednesday the 15th has a tiny 1ft swell from the west with a very long 21-second period, but the wind is onshore and ruins it. Bigger days like Wednesday the 8th (7ft) with strong cross-onshore winds would be better for kite surfing than paddling.
So, save your energy for the Monday the 13th glass-off. The rest is a waiting game.

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