The Lowdown
Alright folks, Rusty here. Let’s take a long, hard look at what’s cookin’ for Kihei Cove.
Right off the bat, we’ve got a reef break that’s very consistent, which is a good sign for a place that’s fairly exposed. The water is sitting at 80°, which is pretty much normal for this time of year – nothing weird going on there. The main thing to know is that the first few days are going to be small, real small. We’re talkin’ ankle-to-knee high stuff, not much to get excited about. The real standout window is further out, but we’ll get to that.
The period kicks off Wednesday, August 19th with a tiny 1 ft SSW swell, but we’ve got a nice cross-off wind from the NNW. It’s surfable, but it’s very ordinary. The combined energy is weak at 172, so you’re not gonna feel much push. Thursday, August 20th, the swell nudges up ever so slightly to 2 ft, and the morning is glassy. That’s about as good as it gets for the conditions, but the waves are still small. Friday, August 21st, the morning wind is onshore, so it’s a bit messy. The afternoon cleans up with glassy conditions, but again, it’s small.
We hit a bit of a rough patch on Saturday, August 22nd morning. The surf is poor – a cross-shore wind with small ripples. Not worth paddling out. The afternoon does clean up with a gentle offshore from the NE, but it’s still only 2 ft. Sunday, August 23rd, is much the same: clean but tiny.
Now, here’s where it gets interesting. From Monday, August 24th, through the end of the month, we see a gradual increase in energy. The morning of the 24th is glassy with 2 ft from the SSW, and the combined energy is climbing to 224. It’s still small, but it’s getting better. The real standout for the whole outlook is Thursday, August 27th. The morning brings a 3 ft swell from the south, with a long period of 16 seconds. The combined energy jumps to a solid 546, which is moderate, and it’s glassy. That’s a clean, groundswell for the reef. The afternoon is also clean with a light offshore breeze. This is the best on offer – a true standout for the whole 16 days.
After that, the energy drops off again. The rest of the month and into early September, we’re back to small, ankle-high waves with energy numbers falling back to the 100s and lower. The 1st and 2nd of September are pretty ordinary, and the 3rd of September has a bit of rain with a tiny 1 ft that’s glassy but not much else.
So, if you’re looking for a wave, the best bet is to hold out for the morning of Thursday, August 27th at Kihei Cove. The swell direction is S, coming right in for the reef, and the period is long enough to have some shape. It’s a beginner spot, so this size is perfect. The rest of the time, it’s mostly small and clean, but that one morning is the real standout.
Rusty.

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