Dumbea Left Surf Forecast and Surf Report

Alright, this is Rusty, and I’m looking at the forecast for Dumbea Left. This is a reef setup over at Dumbea. Water temps are sitting around 74°F, which is pretty much what you’d expect for this time of year – nothing weird going on there.

The next few days are where the real action is. The standout window is from Friday afternoon, July 17th right through to Sunday, July 19th. We’ve got a solid SSW groundswell moving in with a very long period of 17 to 21 seconds. That’s some serious energy for a reef break. On Friday afternoon, expect 4ft waves from the ESE with a clean, gentle offshore wind from the NE. The combined energy is moderate (543), but it’s clean and it’s setting up.

The real highlight hits Saturday, July 18th. Saturday morning is a bit risky with storms around, but the wind is light offshore from the NE at 6 mph. The swell is 4ft from the SSW at 17 seconds, and the energy jumps to 925. Then Saturday afternoon, the wind picks up to a moderate offshore from the ENE at 12 mph, and the swell bumps up to 5ft with a 17-second period. The energy is strong (1643). This is excellent, clean surf for experienced surfers. The long period and SSW direction are perfect for this reef. Crowds are sometimes a thing here, so you might have some company, but it’s worth it.

Sunday morning, July 19th also looks good – 4ft SSW swell, 21-second period, and a gentle cross-offshore wind. The energy is very strong (2244). That’s a lot of power for a reef. Sunday afternoon gets a bit dicey with a strong cross-offshore wind at 25 mph and 5ft waves, which is getting into the "experts only" territory.

From Monday, July 20th onwards, the wind starts to swing cross-shore and onshore, making things choppier and messier. The swell sticks around but the quality drops off. There’s a bit of a lull. Thursday, July 23rd sees a drop in swell size and period, and the wind is pretty fresh.

Then, there’s a second chance starting Sunday, July 26th. The SSW swell returns with a 16-second period and moderate energy. The winds are cross-offshore, so it’s clean. The wind on Monday, July 27th goes glassy in the morning – zero wind, 5ft SSW swell, 15-second period. That’s a real treat. Tuesday and Wednesday, July 28th and 29th, still have some clean windows but the wind starts to mess with it a bit.

After that, it’s a long stretch of poor surf from July 30th all the way through the end of the forecast. The swell size drops below 3ft, and the winds are onshore or cross-shore, creating lumpy, choppy conditions. Not worth paddling out.

So, the pick of the surf is this weekend – Saturday, July 18th and Sunday morning, July 19th. That’s the best mix of solid groundswell and clean offshore winds. If you miss that, keep an eye on Monday morning, July 27th, when the glassy conditions look promising, but it’s a bit further out and less certain.
