Alright folks, Rusty here with your long-range look at what's on offer. The next couple of weeks are looking like a bit of a mixed bag, but we've got some definite windows of clean surf to get excited about.
The period kicks off with a fresh pulse of groundswell. Water temps are sitting at a warm 86.4°F, which feels a touch warmer than normal for this time of year. The overall swell energy is moderate, clocking in at 754.
Monday, July 6th is a nice way to start the week. Guiones will see a clean 3ft SW groundswell with a very long 16-second period, all under a light offshore NE breeze. It's not huge, but it’ll be clean and fun. The afternoon sees the wind go a bit suspicious with a light cross-onshore, but the morning is the clear winner.
Tuesday, July 7th is shaping up to be your standout session. Another morning of clean 3.6ft surf from the SW gets better through the day, with the afternoon turning on for us. We’re looking at 4.6ft of SW groundswell, with a 18-second period, going completely glassy. Combined swell energy jumps to a strong 1247. That’s the pick of the early period – uncrowded for a Tuesday, as this spot can get crowded often, but the quality will be worth it.
Wednesday, July 8th holds a similar early vibe with a glassy 4.3ft SSW swell, but the afternoon cross-onshore wind will mess things up a bit.
From Thursday the 9th through to the weekend of the 12th, we're still seeing solid 3ft to 3.6ft swells but the energy drops a bit. Conditions will be variable with wind and a risk of thunderstorms, so the cleanest windows will be the early mornings when the offshore breezes kick in. It's still fun, just not as polished as Tuesday.
We then hit a bit of a lull from around the 13th through the 16th. The swell dips, and while there are pockets of clean surf in the mornings, it’s not going to be setting any worlds on fire.
Looking into the second week, things start to look promising again. Sunday, July 19th bumps back up with a clean 3.3ft S swell. It’s worth a morning paddle for sure. Then, Monday, July 20th brings a really interesting call. A 2ft SW groundswell with a very long 17-second period under offshore winds. The energy reading of 657 is actually quite punchy for the size. That long period will wrap in nicely and create some beautiful, lined-up waves, likely with nice long lulls between sets.
Tuesday, July 21st also has a clean morning on offer with another 2.6ft SW groundswell.
So, for the best of it, make a beeline for Guiones on Tuesday the 7th for the glassy 4.6ft set, and keep an eye on the 20th and 21st for some classic, long-period groundswell. The long-period stuff is best on a point or reef, but Guiones can handle it.
Stay stoked.

Information about the Guiones Surf forecast
The above surf forecast table for Guiones provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Guiones can be found by selecting the local surf guide option on the grey menu. Our Guiones 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 (Guiones) 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 Guiones 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.
Guiones is 34 km (21 miles) from Nicoya. If you plan a holiday in Guanacaste, look for hotels and other accommodation in Nicoya. Nicoya has rooms for a wide range of budgets as well as car hire and transport links.
