The Lowdown
Alright folks, Rusty here in imperial. Let’s break down Rosa’s next couple weeks.
Tuesday 14 July starts off sweet: glassy morning, 5.9ft SE swell at 10 seconds, combined energy 618 – moderate but clean. Offshore NW breeze, so waves will be lined up. Crowds show sometimes, but early Tuesday should be fine.
Then it goes south. Tuesday afternoon turns choppy and cross-on, and Wednesday through Saturday are all poor – cross-shore winds, bumpy. Saturday 18 July pumps 7.5ft NE swell, but cross-shore wind ruins it – energy jumps to 1183 but messy.
Sunday 19 July is the best of the lot. Morning already clean with offshore W wind and 5.9ft ENE swell, but the afternoon is killer: light offshore west breeze, 6.6ft NE swell, 8-second period, energy 983. Glassy, punchy, perfect. Don’t miss it.
Monday 20 July is marginal – small, rippled. Tuesday 21 July morning marginal, but afternoon brings a gem: 3.3ft S groundswell at 12 seconds, light cross-offshore NNW, clean, energy 509. Long period means better shape, wider sets.
Wednesday 22 July is another cracker: both sessions clean with cross-offshore SW/SSW wind, 4.9–5.2ft S swell, 10-second period, energy 650–935. Fun all day.
Then Thursday 23 July goes messy again, Friday 24 July poor, Saturday 25 July has 6.9ft NE but cross-chop. Sunday 26 July and Monday 27 July poor/marginal. Tuesday 28 July small but clean, and Wednesday 29 July morning offers a little clean 3ft SE swell with offshore light wind.
Best bets: Sunday afternoon the 19th and Wednesday the 22nd

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