The Lowdown
Alright folks, Rusty here. Let’s break down what’s happening at Tetitlan over the next couple of weeks.
First up, we have a proper window on Monday the 20th of July. The morning is the clear winner: a clean 4ft SW groundswell with a very long 16-second period. The combined swell energy is strong (1055). The wind is glassy, near calm, so the surface will be smooth as glass. This is excellent surf, but for experienced surfers only. The water temperature is about average for this time of year. Crowds are a possibility, so plan for it.
The following mornings – Tuesday the 21st through Thursday the 23rd – all deliver glassy starts with chest-high swell from the SW. The energy drops a bit (from 743 down to 354), but it’s still clean and fun. The afternoons get choppy with a cross-onshore breeze, so the early bird catches the wave.
The highlight of the first week lands on Friday the 24th of July. The morning brings a tiny but incredibly long period groundswell from the SSW with a 24-second period. That’s a very long period, and with 906 energy, it’ll have plenty of punch for the size. It’s glassy and clean, and on a reef setup, that long period will wrap in beautifully.
The absolute best of the bunch is the weekend. Saturday the 25th and Sunday the 26th of July both have dead calm, glassy mornings with a solid 4ft to 5ft SW groundswell. The energy is strong (1298 on Saturday, 1805 on Sunday), and the period is a long 21 to 18 seconds. This is top-tier, excellent surf for experienced surfers. The wind is zero, so it’s as clean as it gets.
The following week, from Monday the 27th of July, the swell pushes higher. We’re looking at 6ft to 7ft SSW groundswell with very strong energy (2319 to 2719). The mornings are glassy, but this is expert territory now. Too big for beginners. By Thursday the 30th and Friday the 31st, it backs down to a more manageable 5ft SSW, still clean and glassy, and a good option for the strong intermediate.
The first week of August looks quiet. The swell fades, the wind turns cross-shore, and the energy drops into the weak range (338 to 363). By Sunday the 2nd of August, there’s a small, clean, cross-offshore window with 2ft SW swell, but it’s just a whisper. The forecast goes quiet from there.
So, the real standouts are the mornings of Saturday the 25th and Sunday the 26th of July. That’s the cream of the crop. The following week also has some solid, clean energy for the experts.

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