The Lowdown
Alright folks, Rusty here. Let's have a look at what's cookin' for Rhos-On-Sea over the next couple of weeks.
To be straight with you, this is a quiet stretch. We're looking at a long run of small, weak, and frankly poor surf conditions. The biggest issue is the total lack of decent swell energy. The numbers are tiny, like 40 (weak energy) or less, and most of the time it's just flat.
The first few days, from Thursday the 23rd to Friday the 24th, we've got tiny waves. On Thursday morning, we're looking at a 3ft swell from the NW with a short period of 5 seconds, and a combined energy of just 40. The wind is a light cross-offshore from the WNW, so the surface will be clean, but don't expect much to ride. It's inconsistent and, frankly, poor. By Friday afternoon, the swell drops to 1ft and the energy is down to 5. It's a struggle.
After that, from Saturday the 25th right through to the end of the month, we're looking at a big gap. The swell is completely gone. There's nothing to ride. The water temp is about average for this time of year, so no drama there, but without waves, it doesn't matter.
We get a tiny flicker of life on the 1st of August. Saturday morning shows a 0.3ft NW swell, but the energy is a measly 1. Then again on the 2nd of August, Sunday afternoon, there's a 1ft swell from the NNW with a 5-second period, and energy bumping up to 11. The wind is moderate offshore from the SW, which would clean it up, but with waves that size and period, it's still a poor surf day.
The rest of the first week of August stays flat, with tiny blips of 1ft swell on the 4th and 5th, but nothing that's going to get the heart racing. The energy stays in the single digits or low teens.
Honestly, the standout – if you can call it that – is probably the Sunday afternoon of the 2nd of August. It's the only time the swell gets over 1ft with a clean offshore wind. But it's still a tiny, weak wave for intermediate surfers. Don't expect much.
This is a real dry spell. It won't stay poor forever, but for now, the forecast is a blank run. We're just waiting for a proper pulse of energy to show up.
Rusty, signing off.

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