Alright, Rusty here, checking in on what's shaping up for the Rosa stretch. We've got a bit of a slow start, but the gears start turning by mid-week and there's some real quality further out.
The first few days are pretty low-key. Monday the 6th shows a small 4ft SE swell, and it's bumpy in the morning, but cleans up nicely in the afternoon with a light cross-offshore breeze. The water temperature is sitting at 60°, which is over 5° colder than usual for this time of year, so you'll be needing a thicker wetsuit for sure. The energy is moderate (608) but the waves look a bit weak.
Tuesday the 7th is when things start to get interesting. We get a bump in size to 5ft from the S, with a clean cross-offshore wind all morning. It's a short-period swell at 8 seconds, so it'll be a bit punchy and dumpy, but it's consistent and the wind is right. The afternoon will see the wind shift, making it a little wonky.
Now, if you can hold out, Sunday the 12th afternoon is where the magic starts. We get a jump to 8ft from the S, with a clean cross-offshore breeze. The wave energy is pumping at 1471, and the report is calling it excellent for experienced surfers. This is a proper step-up, solid and powerful, not for the faint of heart. The consistency is good, and with those conditions, it'll be a session to remember.
But the real standout, the one you want to circle on the calendar, is Friday the 17th of July morning. We've got a clean 7ft swell from the S with a 13-second period. That's a proper groundswell, and it's wrapping in with a light offshore wind. The combined energy is a massive 1555. With a long-period swell like this, Rosa (a break I imagine is exposed to the open ocean) will have some serious lines, power, and shape. This is the best on offer for experienced surfers, no question. The wind is going to be clean, and the sets will be well-spaced, making it a lot easier to get into position.
After that, the surf hangs in there through the following week, with plenty of 4ft to 5ft S swells and clean conditions, but nothing quite compares to that 17th.
Alright, that's the rundown. The early week might be a bit of a tease, but a good surf fisherman waits for the right swell. Get your gear ready.

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.
