The Lowdown
Alright, this is Rusty, and I’m looking at what’s on the table for the next couple of weeks. Macaronis is the only spot in the picture, and it’s a world-class reef break that needs a good setup. The water is sitting at 85°F, which is pretty much normal for this time of year, so no surprises there.
The first few days are a bit of a write-off. Monday the 7th and Tuesday the 8th have some swell around, but the wind is cross and cross-shore, making for a messy, choppy surface. The waves are there, but they’re not clean. The combined energy is moderate to strong, but the quality just isn’t there. We’re looking at a gap of poor and marginal conditions from the 7th through to the 11th.
Now, the standout window is shaping up for Saturday the 12th. That morning, we’ve got a 5ft SSW swell with a very long period of 19 seconds, and the wind goes light and cross-offshore. The combined energy jumps, and the wave comment calls it excellent for experienced surfers. This is the real deal – a long period groundswell at a reef, with clean conditions. The afternoon gets a bit bigger, around 6ft, but the wind swings cross, so the morning is the pick. The swell direction is SSW, which is close to the optimum SW direction for this spot, so the waves should wrap in nicely.
Sunday the 13th looks bigger, around 7ft, but the wind is cross and a bit stronger, so it’s not as clean. The energy is still strong, but the conditions are marginal. The following week, from the 14th to the 16th, the swell stays in the 5ft to 7ft range, but the wind is mostly cross, keeping things from being top-tier.
The second week has a couple of promising days. Thursday the 17th morning has a 6ft SSW swell with offshore wind from the NE, making for clean conditions. Then, Saturday the 19th looks like a real treat. The morning has a 6ft SSW swell with light wind, and the afternoon goes glassy with a 6ft SSW swell. The combined energy is strong, and the wave comments call it excellent for experienced surfers. That Saturday afternoon is the best of the second week, with glassy conditions and a solid swell.
If you’re a beginner, most of the good swell is over 5ft, and some days push 7ft, which is expert territory. The long period swells (15+ seconds) are frequent, so the wave shape will be excellent, but the long gaps between sets make paddling out easier. This is a reef break, so it handles those long swells well.
Crowds are possible at Macaronis, so keep that in mind.
Overall, the best on offer is Saturday the 12th morning, with a close second being Saturday the 19th afternoon. Everything else is a wait-and-see game.
Rusty.

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