The Lowdown
Right then, let’s take a look at what’s coming up for Makaha. This is a spot that’s very consistent and exposed to the swell, so it always has something to offer, but the quality is going to be all over the shop for the first while. The water temp is sitting at 71°, which is much warmer than normal for this time of year – a solid 9° above average, so you’ll be comfortable in a shorty or less.
We kick off on Tuesday, the 18th of August, and it’s a bit of a messy start. We’ve got a solid 7 ft to 8 ft SW groundswell rolling in with a long period of 12 to 13 seconds, and the combined energy is strong (1325 to 1819). But, the wind is blowing cross-shore from the SSE at 12 to 16 mph, putting a cross-chop on it. It’s surfable for sure, but it’s not going to be clean. Wednesday looks similar with a 7 ft SSW swell, though the period drops a bit. The wind is a little lighter from the south at 9 mph, still cross-shore, so still a bit lumpy.
Then on Thursday, the 20th of August, things finally turn. We’ve got offshore wind from the WSW at 6 mph in the morning, blowing straight into the face of a 6 ft SSW swell with a 9-second period. The combined energy is moderate (648). This is your standout window for the first week – clean conditions on a solid, fun-sized swell. The afternoon sees the wind go cross-on, so definitely hit the early session at Makaha.
After that, the swell backs way off. From Friday the 21st through the middle of the following week, we’re looking at waist-to-chest high waves at best, with mostly cross or cross-on winds. The combined energy drops into the hundreds – weak to moderate. It’s a bit of a flat spell, honestly. The period gets very long on the 22nd and 23rd (19 seconds), but the swell height is only 1 ft, so it’s just a long-period wobble with no real push. This is a stretch where you’d be better off taking the kayak out.
We then see a bit of a rebuild starting around Friday the 28th of August. A new SW groundswell fills in, with 3 ft to 5 ft waves and a long 16 to 18-second period. The energy jumps back into the strong range (1057 on Friday afternoon). The wind stays light cross-on from the SSW at 6 mph, so it won’t be perfect, but it’s a promising sign.
The best bet of the entire forecast is Saturday, the 29th of August. We’ve got a solid 6 ft SW groundswell with a 14-second period, and the combined energy is strong (1575). The wind in the afternoon is cross-shore from the south at 9 mph, but it’s a gentle breeze, so just a slight cross-chop. This is the biggest and most energetic window on offer. Sunday the 30th holds similar 6 ft SW swell with light winds, too. After that, the swell drops off again heading into September.
So, for the whole 16 days, the true standouts are Thursday morning, the 20th of August for the offshore wind and solid waves, and then Saturday the 29th of August for the biggest, most powerful swell of the run. Get on it.

Information about the Makaha Surf forecast
The above surf forecast table for Makaha provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Makaha can be found by selecting the local surf guide option on the grey menu. Our Makaha 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 (Makaha) 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 Makaha 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.
Makaha is 2 km (1 miles) from the city of Lima. If you plan a holiday in Lima, look for hotels and other accommodation in Lima. Lima has rooms for a wide range of budgets as well as car hire and transport links.
