Updates in hr min s Forecast update imminent
Alright, surfers, Rusty here. Let’s look ahead at what’s on the cards for the coming weeks.
We’re starting off with a solid pulse of south-west groundswell, and it’s not going to be a quick session. The first real action is Friday morning the 3rd of July, and it's all focused on one spot.
Cow Bombie is an exposed reef break that demands respect – this is strictly for the experienced crew. It’s inconsistent by nature, so you need patience, but when it comes, it comes with serious power. On Friday morning we’ve got a clean 10-foot SW groundswell with a long 14-second period, making for some real push. The wind is a cross-offshore light breeze, so the face should be smooth. The wave energy is strong at 3200, and it’s looking excellent for those with the skill to handle it. This is proper stuff.
The swell holds through the weekend but the wind gets a bit more challenging. Saturday morning the 4th of July still has 10-foot SW swell, but a moderate 16 mph cross-off breeze will make it a bit lumpy. By Sunday the 5th of July, a strong onshore wind makes a mess of things.
Now, here’s where it gets interesting. Look ahead to Monday the 6th of July. The swell jumps to a powerful 13 feet from the WSW with a 15-second period. The wave energy is very strong (6317). The morning is clean with a moderate cross-off breeze. This is still too big for beginners (over 8 feet) and is expert-only territory, but it could be a wild session for those who can handle the peaky sets.
But the highlight of the whole outlook lands on Sunday the 12th of July. That morning, Cow Bombie will see a massive 13-foot SW groundswell with an exceptionally long 17-second period. The combined wave energy is extremely strong, reading 10335. To top it off, we’ve got a gentle cross-off breeze keeping it clean. The afternoon is forecast to be glassy with zero wind, which is about as perfect as it gets at a gnarly reef. This is a standout day, but it’s two weeks out, so keep an eye on the long-range forecasts. It’s promising, but don’t book the plane ticket just yet.
After that, the swell drops back to the 8-foot to 10-foot range, with cleaner conditions through Tuesday the 14th of July under a moderate offshore easterly. By Thursday the 16th of July, the wind swings north and starts to blow with fresh strength, making the surf lumpy, before a full-blown onshore mess closes out the window on Friday the 17th of July with heavy rain and strong winds.
In summary: Cow Bombie is your only game in town, and for the experienced surfer, the 12th of July is the real date to circle on the calendar – a huge groundswell with glassy conditions. The first week has some solid moments too, especially Monday and Tuesday.
Stay safe, respect the reef, and I’ll see you out there.

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 Cow Bombie 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.
