The Lowdown
Alright, let's talk straight. The next couple of weeks are going to be a fight. There's swell around, but the wind is going to have its way with it, keeping things choppy and messy. We’re looking at a lot of blown-out conditions, so you're gonna have to pick your moments.
We start with a dud on Tuesday the 8th. A solid 7ft of WNW swell, but a fresh NW breeze on top of it will turn it into a washing machine at Perranporth. The energy is moderate (677), but it’s going to be poor. Water temp is 65°, which is a touch warmer than usual for this time of year.
Wednesday the 9th and Thursday the 10th are more of the same, with the wind staying onshore and cross, putting a nasty lump on a 6ft swell on Thursday afternoon. Friday the 11th offers a small push to 5ft, but a NNW cross-on wind keeps it average.
The one small window we get in the near-term is Sunday morning the 13th. The wind drops to almost nothing, and we have 5ft of clean W swell. It's a marginal call with the energy at 369, but it might be rideable. The rest of the weekend and Monday gets messy again.
Now, next Tuesday the 15th is your standout. The morning is looking clean, with a gentle offshore SE breeze and 3ft of W swell. That longer period of 11 seconds gives it some punch. This is your best bet for a proper surf. The afternoon stays clean too, but the morning is the pick.
Then it dies. From the 17th to the 21st, the swell drops out completely. We’re talking knee-to-waist high dribble with onshore winds. It's a dead period, so find something else to do.
Just when you think it's over, we get a few interesting mornings the following week. Saturday the 19th is completely glassy with 3ft of WNW swell – it’ll be small but clean. Then the 20th and 21st have a moderate offshore ESE wind with 2ft to 3ft waves, again clean but small.
The real kicker is Wednesday the 23rd. A long-period WNW swell shows up with a 14-second period. It's small, around 3ft, but that long period is a sign of proper groundswell. The wind is light and cross-on, so it’s not perfect, but that one has serious potential. It's a long way out, so don't get too excited yet, but keep it on the radar.
So, Tuesday the 15th is your day. The rest is a waiting game for those cleaner mornings and that long-period pulse on the 23rd.

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