The Lowdown
Hey, Rusty here. Let’s break down what’s headed to Strandhill.
Right from the start, the 8th of September is ugly: rain showers and strong onshore wind, 2.5m WNW swell (combined energy 1351) but it’s a total mess – that’s more for kite gear than a surfboard. That poor run continues through Thursday the 10th, with tiny swell and weak energy (83). Nothing to get excited about.
By Thursday afternoon the 10th, we see a little 1.3m WSW swell but it’s still choppy with cross-shore wind. Friday the 11th stays so-so with bumpy 1.4m to 1.6m and moderate cross-onshore wind.
Saturday the 12th brings a solid 2.2m to 2.3m west groundswell, 12-second period, and combined energy up to 1463. The wind is cross-shore and the water’s chopped up, so it’s a messy power session for strong paddlers.
The real gem is Sunday morning, the 13th of September. Glassy conditions, 1.2m WNW groundswell with an 11-second period, combined energy of 308 – dead calm wind. That is clean, fun surf. Water temperature is 16°C, a touch warmer than average for this time of year. Crowds are possible here, but that early glass is your best bet of the whole forecast.
The rest of the month is hit and miss. Monday the 14th and Tuesday the 15th are cleaner but with moderate wind, waves around 1.1m to 1.5m – alright but not standout. Wednesday the 16th is back to strong onshore wind and rain.
Thursday the 17th of September morning is another good one: 1.6m WNW groundswell, 10-second period, combined energy of 482, with clean cross-off wind. A solid day for a surf.
Then we go small and weak from the 18th to the 20th – waves from 0.5m to 1.0m. Monday the 21st of September morning lights up again: 1.3m west swell, 12-second period, combined energy of 456, with light cross-off wind. That long-period west swell at a beach break can be a bit straight, but if the banks are good it’ll be fun.
Finally, Wednesday the 23rd of September pumps out a big 2.3m WNW swell with a 15-second period, combined energy of 2351 – serious power, but cross-onshore wind ruins the shape. Only for experts and even then, it’s a tough day.
So, if you’ve got one session to make, hit Sunday morning the 13th. Thursday the 17th and Monday the 21st are your fallback mornings. The rest is mostly small or blown out.
Rusty.

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