Alright folks, Rusty here. Let's be straight with you. I've had a good look at the charts for the 16-day window, and the news isn't what any of us wanted to hear. The entire forecast period is a write-off for Irmas/Leftpoint. There isn't a single session that gets the nod. Every single day, from Friday the 10th of July right through to Saturday the 25th of July, the combined swell energy (506) is moderate at best, but the wind is just relentless. It's a constant cross-shore or cross-onshore breeze, blowing at 15 mph to 25 mph, which is going to leave the place a lumpy, choppy mess. The swell is mostly short-period, 7 to 8 seconds, coming from the ENE, which is not the optimum direction for this reef. The water temp is sitting at 79°, just about bang on average for the time of year.

For most of the 16 days, the swell is hanging around 5 ft to 8 ft, but with that wind, it's going to be poor surf conditions. There is a tiny window around the 15th of July where we get a flash of a longer-period SSW swell, but it's tiny at 2 ft and the wind is still on it. A few days later, around the 22nd of July, we see a similar story with a 13-second S swell, but again, the height is barely 2 ft and the wind is cross-onshore, keeping it choppy. The very end of the run, from the 23rd to the 25th of July, has some more promising longer-period SSW groundswells—16 to 21 seconds—with the energy climbing up to 902, but the heights are still only 2 ft to 3 ft and the wind is still cross-shore and fresh. You'd be fighting a losing battle.

Honestly, there's nothing to get excited about here. It's a long stretch of messy, blown-out conditions. If you're desperate, you might find a rare clean wave, but don't count on it. This area is pretty consistent, so a blank run like this is a bit of a surprise, but forecasts can change. For now, I'd say park the board and find something else to do.

Rusty.

Information about the Irmas/Leftpoint Surf forecast

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