The Lowdown
Alright folks, Rusty here. Let's have a look at what Trestrignel has in store for us over the next couple of weeks. I gotta be straight with you – it’s a tough outlook. The swell is mostly on the small side, and the wind is rarely playing ball. The water is sitting at 66°F and is a touch warmer than normal for this time of year, which is a nice little bonus if you're getting in.
We kick things off on Friday the 28th of August, but there's nothing worth paddling out for. The wind is a fresh cross-onshore with a lumpy mess, and we're only seeing ankle-biters at 2 ft from the WNW. The combined energy is a weak 65, so don't bother.
Saturday the 29th of August sees a bit more size in the morning, 4 ft but from the WSW with a short, weak 6-second period. The wind is a cross-off, so it looks clean, but the swell is too weak and chopped to get excited about. The energy is still only moderate at 144. By the afternoon, the wind goes nuts – a near gale cross-shore at 31 mph with 12 ft of chaotic, crossing waves. That's a big number for energy at 2313, but it's a total write-off for surfing. Possibly more interesting for the kite crew.
Sunday the 30th of August is disappointing. The morning has 5 ft from the W, clean with a cross-off, but the energy is still moderate at 389. The afternoon gets a bit messy again with a fresh cross-shore breeze. The pattern continues through the end of August and into early September: small to moderate W and WNW swells, but the wind is always cross, cross-on, or cross-off, leaving the surface lumpy or choppy. There's a brief window on Wednesday the 2nd of September morning with 3 ft and clean conditions, but it's tiny.
The standout for the whole period, if you can call it that, is Saturday the 5th of September. The morning has 4 ft from the WNW with a light cross-on breeze and a combined energy of 227. It's not perfect, but it's the most manageable and least messy looking session for a while. The afternoon improves slightly with a NNE wind, but it's small.
After that, we slide into a long stretch of weak, inconsistent surf. The swell drops off and the periods are short, with the wind often onshore. There's a small spike around Monday the 7th of September afternoon with 5 ft, but it's a short-period windswell from the W with a period of 7 seconds. The energy is moderate at 262, but the quality won't be there.
The rest of the forecast is a quiet run. The swell stays small, rarely above 3 ft, and the wind keeps it messy. The last few days are particularly weak. To be honest, there's nothing here that's going to get the heart racing. I'd keep an eye on the forecasts, but don't cancel any plans.
Rusty.

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