The Lowdown
Alright folks, Rusty here. Let’s get straight into it.
First up, we’ve got a pretty bleak outlook for the coming weeks at Irmas/Leftpoint. The wind is locked in from the ENE, blowing hard and cross-shore, which is a recipe for lumpy, messy conditions. The pattern is clear: there’s no real clean surf on offer for the first ten days or so. After that, the swell energy picks up but the quality remains poor, so we’re looking at a long stretch of disappointment.
The first chance of anything rideable comes on Saturday the 25th of July, but even then it’s a marginal call. The swell is 8 ft from the ENE with a short period of 8 seconds, so it’s a messy, wind-affected wave. The cross-shore wind is still fresh at 19 mph, so it’s going to be lumpy. The combined energy is moderate (1405), but the conditions are just not there for a clean session. It’s really only for the die-hards who don’t mind a fight.
The standout period, if you can call it that, is the end of the first week of August. On Sunday the 2nd of August, the swell is 5 ft from the NE with a period of 7 seconds, still short and choppy. The wind is fresh cross-shore at 19 mph, so it’s lumpy again. The combined energy is moderate (614). Honestly, there’s no single day that screams “go now.” The wind is never truly offshore or glassy, and the swell direction is almost always from the east, which is not the optimum ESE direction for this reef. The water temperature is about average for the time of year, so no surprises there.
Overall, I’d say the best bet is to sit this one out. The forecast shows a gap of about ten days with no real surf, and then it’s just marginal at best. It’s a tough run for Irmas/Leftpoint, and the ENE wind is the villain here. Keep the board in the car, but don’t get your hopes up.
