Table - best surf conditions forecast for Roaches Reef over the next 16 days.


The Lowdown

Alright, this is Rusty. Let's get into it.

First up, the water temp at Roaches Reef is sitting at 68°F and that's a whopping 7°F warmer than usual for this time of year. That's a very unusual anomaly, so you'll be in for a real treat on that front if you're paddling out.

The next 16 days look like a real mixed bag. We've got a solid pulse of swell on the way, but the wind is going to be a nightmare for most of the first week. The early part of the window is a write-off for decent waves. Friday the 4th and Saturday the 5th are a no-go with strong cross-shore winds and lumpy, choppy conditions. The swell is there, but it's blown out. Sunday the 6th is tiny and weak, with a combined energy of just 42, so don't bother.

The first real standout comes on Monday the 7th. The swell jumps up to 6ft from the WSW with a very long period of 13 seconds, giving it some serious energy (1042). That's a proper groundswell. Now, the wind is a moderate cross-shore, which is a bit of a bummer, but the sheer size and period mean it will be breaking with some power. The caveat here is that a long period swell like this can be tricky at a reef break, making it a bit walled-up, but it's the best wave we're going to see for a while.

Tuesday the 8th through Thursday the 11th are all pretty average. The wind stays on it, and the quality is poor. The only good news is that by Friday the 11th, the wind swings offshore and we get clean conditions, but the swell has dropped to a marginal 4ft.

The real gold is waiting for you in the second week. The best on offer is looking like Thursday the 17th. The morning starts with a clean 4ft from the W, and by the afternoon it's a dream. The wind is going to be a gentle offshore from the NNE, the swell is 4ft from the WSW with a solid 10-second period, and the combined energy is a solid 389. This is a classic setup for a reef break. Then Friday the 18th morning is also a standout: 6ft from the W, clean offshore wind from the N, and energy of 371. That's a proper fun size. Keep in mind these late-week calls are a bit more promising than certain, but the data is pointing that way.

The rest of the second week drops off into tiny, clean but small waves, with the 19th offering a glassy 3ft but very weak. For the whole 16-day window, the 17th afternoon and 18th morning are the ones to circle on the calendar.

Rusty.

Information about the Roaches Reef Surf forecast

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