The Lowdown
Alright, Rusty here. Let's have a look at what's on the table for the stretch ahead.
Right off the bat, we're looking at a pretty drawn-out period of small, clean but very ordinary surf. The energy is there, but it's weak. The standout? Honestly, nothing here is firing hard, but for a nose-in-the-air, soul-surf trim, Lahaina Breakwall/Harbour is the spot to be. The water is bang on average for the time of year at 80°, so no surprises there.
The action kicks off Tuesday morning, the 21st of July. We've got a tiny 2 ft S swell rolling in, period 14 seconds, with a combined energy reading of 140 (moderate energy). The wind is a light cross-off from the ENE at 6 mph, keeping things clean. It's surfable, but it's not going to blow your socks off. That afternoon, the wind swings offshore from the NE at 9 mph, and the conditions stay clean, but the swell is still a paltry 2 ft.
Wednesday the 22nd and Thursday the 23rd are a story of persistence. The swell drops to 1 ft, but the period stretches out – 24 seconds on Wednesday morning! That's a very long-period groundswell from the SW, which means it'll wrap in with some push, but it might break a bit straight at the beach. The wind holds offshore or cross-off, keeping the surface clean. The combined energy sits in the 160-190 range, still moderate. Friday the 24th is similar, with a 2 ft SW swell and good offshore winds. The energy climbs to 217 on Friday afternoon, so it's got a little more grunt, but it's still small.
The weekend of the 25th and 26th is more of the same – tiny 1 ft to 2 ft SSW swell, light offshore winds, and clean faces. The energy peaks at 229 on Saturday afternoon, but it's still just a small wave. Sunday the 26th has light rain showers in the morning, but the wind is good and offshore.
Now, we hit a bit of a lull. From Monday the 27th of July through to the end of the month, the swell drops consistently. The combined energy falls into the double digits, under 100, indicating weak wave energy. The waves are still there, but they're struggling to break with any authority. The period is dropping from 15 seconds down to 12 seconds, so the quality is fading.
The start of August doesn't bring much change. Saturday the 1st and Sunday the 2nd have tiny 1 ft to 2 ft swells, with moderate energy. The real low point comes Monday the 3rd of August through to Wednesday the 5th. The swell bottoms out at 1.0 ft, with very weak energy – the combined energy reading is in the 50s and 60s. Conditions are clean, but the waves are just not there. It's a flat spell, plain and simple.
So, for the whole 16-day window, the best on offer is the first week, but even then, it's a long run of very small, clean surf. There's no big, powerful swell to get excited about. The crowds at Lahaina Breakwall/Harbour are listed as "sometimes" busy, so you might have a few friends out, but with waves this small, it won't be a zoo.
If you're looking for a wave to actually ride, the best bet is the first few days, especially Tuesday the 21st and Wednesday the 22nd of July, when the swell is at its peak and the winds are light. It's not a classic, but it's clean and rideable. After that, you're mostly just bobbing around.
Rusty.
