The Lowdown
Right then, let’s have a look at what’s on the cards for Manorbier. Honestly, it’s a pretty quiet run for the next two weeks, with a long stretch of nothing much happening. The water temperature’s sitting at 66°, which is much warmer than normal for this time of year, so that’s a nice bonus if you’re getting in.
We’re looking at a big gap of poor conditions right through the first week. From Monday the 17th all the way through to Sunday the 23rd, it’s mostly cross-shore and cross-onshore winds, with weak little waves and a lot of chop. The combined energy is weak, around 53 to 126, so nothing’s really building. There’s a small window on Thursday morning the 20th where it’s clean with a cross-offshore wind and a 5ft swell from the WSW, but it’s only marginal and the tide might mess with it. Friday the 21st and Saturday the 22nd are tiny and clean, but the swell’s barely 2ft, so not worth paddling for.
Then it goes dead flat from Sunday the 23rd right through to Tuesday the 25th, with combined energy dropping to as low as 14. That’s a proper lull, and you’d be better off doing something else.
Things start to stir again on Wednesday the 26th, with a bit more energy coming in – 4ft from the WSW, but the wind’s onshore and choppy, so it’s still messy. The combined energy climbs to 242, but it’s not clean. Thursday the 27th is similar, with 6ft from the SW in the afternoon, but again onshore wind.
The standout in the whole outlook is Friday the 28th morning. Now, that’s a week and a half away, so keep it in mind but don’t book the day off yet. We’ve got a 7ft swell from the WSW, period 10 seconds, and the combined energy is strong at 766. The wind is light cross-onshore, just a light breeze, so it’s not perfect but it’s the best we’ve seen. The swell’s a bit big for beginners, though, at over 7ft, so it’s more for the experienced crew. Manorbier is a beach and point setup, exposed to SW swell, and with a 10-second period it should have some decent shape, but the cross-onshore wind might keep it a little lumpy.
Saturday the 29th drops off again with strong cross-onshore winds, and Sunday the 30th has a 7ft onshore swell that’s still marginal. Monday the 31st has a big energy spike at 1364 with a 7ft W swell, but it’s got a risk of thunderstorms and a fresh cross-onshore, so it’s wild and messy. Honestly, that’s more kite-surfing territory than clean paddling.
So, if you’re keen, circle Friday the 28th morning. It’s the only real chance for something half-decent, but don’t expect perfection.

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