The Lowdown
Alright folks, Rusty here. Let's talk about what’s on the cards for the next couple of weeks. We’re looking at a bit of a rough start, but I'm seeing some potential light at the end of the tunnel if we're patient.
Right off the bat, it's not looking great. We have a solid stretch of onshore and cross-onshore winds combined with some sizeable but messy swell. The water temp is sitting at 64°, which is a touch warmer than normal for this time of year, so at least you won't freeze while you're sitting out there frustrated. That early bit is a write-off for quality waves.
We’ve got about four days of poor conditions to slog through. The wind is howling from the SW on Sunday the 30th, making a mess of things. Monday the 31st sees some size—waves hitting 8 ft from the west with a moderate to fresh cross-shore breeze—but the quality is just not there. We're talking about strong wave energy, but it's all lumpy and choppy. Not what you want.
The first real glimmer of hope comes on Saturday, September 5th. This is the standout of the outlook. The morning is looking clear with a light cross-offshore breeze from the NNW, and we’ve got a clean 6 ft west swell rolling in with a period of 11 seconds. That's a nice groundswell with some decent energy. This will set up really nicely at Poldhu Cove. This is the one to circle on the calendar—clean conditions with proper waves.
However, I have to mention that Poldhu Cove is an inconsistent spot, so don't expect it to be pumping all day. It’s a fairly exposed break, and when that swell lines up with the SW optimum direction, it can really turn on. The crowds will be around sometimes, which makes sense for a spot that doesn't fire off all the time.
The rest of that weekend and into the following week is a mixed bag. The Sunday (Sept 6th) drops right off in size, and we get an odd SE wind that’s just cross-shore. Then Monday the 7th shows a promising 5 ft west swell with a very long 12-second period, but the onshore wind from the WSW will kill it.
Looking further out at the second week, things get small. The wave energy drops significantly. We see some clean conditions from the 8th to the 14th with cross-offshore winds, but the swell height is mostly below 3 ft. The best of that week is looking like Saturday the 12th. The afternoon shows a 4 ft west groundswell with a long 11-second period, clean conditions and a light offshore breeze from the ESE. It's not going to be big, but it will be clean and surfable. That's a "nice if you can get it" session, not a "drop everything and go" session.
So, to sum it up: get through this week of chunky, windy mess, and you’ll be rewarded on Saturday the 5th. That's your best bet for a proper session. The window after that is mostly small but clean for the die-hards.
Stay frothy.

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