The Lowdown
Alright, Rusty here. Let's chew the fat on what's cookin' at Roaches Reef.
Well, I gotta be straight with you – this is a tough stretch. The next couple of weeks are looking pretty flat and lifeless. We're staring down the barrel of a 16-day forecast with barely a ripple to get excited about, and the first few days are a total write-off. It's gonna be a long wait.
The water is sitting at a balmy 69°, which is a whopping 9° warmer than usual for this time of year. It's like swimming in a bath, but there's no surf to enjoy it with.
Looking at the charts, the first real pulse of energy doesn't show up until the morning of Sunday, July 26th. The combined swell energy is still weak at 46, but it's the best we're going to see for a while. We'll have a clean 3ft swell coming from the WSW with a short 6-second period. The wind will be a clean cross-off from the NNW, which is a major positive. This is for the experienced crew only, as it's the pick of a very poor litter.
The pattern continues through Monday, July 27th, with a similar 3ft swell from the W on the morning, but the period is still short and the energy is only moderate (88). The wind stays clean and cross-off, so it'll look good, but it just won't have any punch.
Honestly, the rest of the run is a write-off. We get a few tiny bumps on the 2nd and 3rd of August, but the wind is either howling from the SW or cross-onshore, making a mess of the already small and weak waves. The energy levels are all in the two-digit range, so it's weak.
So, to sum it up: if you're desperate, the Sunday morning, July 26th and Monday morning, July 27th are your best bets for a clean but small wave. The west swell direction is a fair match for the reef. But don't expect much. The rest of the month is a blank unless a sneaky swell shows up. That's just the way it goes sometimes.
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.
