The Lowdown
Alright folks, Rusty here. Let's break down what Rainbow Rocks has in store for the next couple of weeks.
Right off the bat, the start is a bit of a bummer. Saturday the 12th is a no-go – light rain, cross-onshore wind, and the surf is just messy. Not worth getting wet. Sunday the 13th shapes up a little better in the afternoon: 1.6m of WNW swell at 9 seconds, with a clean cross-offshore breeze. That's a glimmer, but the energy is moderate (656). Still, if you're keen, that's your first real shot.
The best of the first week lands on Wednesday the 16th afternoon. The swell bumps to 2.0m from the NW at 8 seconds, but the wind goes light cross-offshore, and conditions clean right up. The combined energy is moderate (694), and the forecast says very good surf. This is a standout – clean lines, decent size, and good for intermediates. Crowds are sometimes here, so expect some company if it looks good.
Heading into the second week, things get more interesting. Saturday the 19th morning is a glassy little session – only 0.6m of long-period SW groundswell (18 seconds) but with glassy conditions. The energy is weak (346), so it's more of a longboard cruiser. Then on Monday the 21st afternoon, things pump up: 3.0m from the NW at 8 seconds, with cross-offshore wind and clean conditions. Energy is strong (1393). This is solid, but at 3.0m it's expert territory – that's a heavy beach-and-reef setup. For the experienced crew, this is the standout of the whole run. However, it's a long-range call so keep an eye on it.
After that, there's a bit of a lull, but Wednesday the 23rd brings a nice 1.3m WNW groundswell at 12 seconds, with gentle cross-shore wind. That's a good all-rounder. The final real highlight is Sunday the 27th afternoon: 1.2m from the NW at 13 seconds, moderate energy (1124), and cross-offshore wind. Clean, long-period lines that will wrap nicely. This one's promising.
Water temp is around 58°F with a +1°F anomaly – pretty average for this time of year, nothing unusual.
All in all, the standout sessions are Wednesday 16th afternoon for cleaner intermediate fun, and Monday 21st afternoon for the experts wanting a big, clean wave. The rest is a mix of marginal windows and small groundswell. Keep the 21st on your radar but don't bank on it yet.
Rusty, signing off.

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