The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s cooking for the next couple of weeks.

To be straight with you, the next 16 days are a real struggle for surf around here. We’re looking at a long, dry spell with nothing worth paddling out for. The first proper recommendation doesn’t even show up until the tail end of the month, so there’s a big gap of quiet conditions from now right through the end of July. The water is sitting at a warm 86°F, which is about normal for the time of year, but that’s where the good news ends.

The only break on the radar is Haad Rin (Kho-Phan-Ngan). This spot is inconsistent and exposed to the east, but the swell we do get is tiny. For the entire first week, we’re talking about 0.3ft of short-period, weak energy (energy values of just 1 or 2) coming from the southeast. The wind is often offshore or even glassy, which would be a dream for clean conditions, but with no wave to ride, it’s just a flat, pretty ocean. The afternoons on the 22nd and 24th go glassy, but again, there’s nothing to surf.

The pattern starts to shift very slightly at the end of the run. Moving into the first week of August, from the 31st of July onward, the swell bumps up to a tiny 1.0ft, still a short 6-second period, but the energy creeps up a little (5 to 10). The winds are clean, with offshore and cross-offshore conditions. The morning of the 1st of August has the highest energy in the whole period at 10, but it’s still a poor surf scenario. This is a very marginal, long-range hint that something might be trying to happen, but it’s too weak and short-period to get excited about.

Given the swell is so small, the conditions are clean, and the energy is so weak, this setup honestly looks more interesting for a kite than a paddle. The best advice is to keep an eye on the forecasts, because it tends not to stay this flat forever, but for now, the boards can stay in the car.

Rusty.
