Alright folks, Rusty here with the outlook for Playa Guiones. We've got a solid run of surf stretching across the next couple of weeks, with a few absolute gems tucked in there. The water temp is sitting about average for this time of year, so the usual rash guard or spring suit will do ya.

The pattern starts Friday, July 3rd morning with a clean 3ft SSW groundswell. The period is a lovely 16 seconds, so those waves have real push, but with that long period, it might be a bit straight for the beachbreak – Guiones handles it well though. The cross-off wind from the NE makes for some tidy faces. That combined swell energy is moderate at 737, a good sign we're in for a session.

Saturday the 4th is the first real standout. Morning brings a glassy 3ft SSW swell (573 moderate energy), with the wind flat calm. That is about as perfect as it gets for a longboard or a funboard. The wave quality will be pristine.

Sunday the 5th holds the theme. The morning has a risk of thunderstorms, but the wind is a light cross-off out of the SE and the swell bumps up just a touch to 3ft SW with a cracking 18-second period. The energy is still moderate at 705, but it’s very surfable. Sunday afternoon goes glassy with a 3ft SW swell (650 moderate energy) – another silky session.

Monday the 6th, get up early. Morning is clear and glassy with a 3ft SW groundswell (754 moderate energy). The afternoons are going to get a bit of a cross-on breeze, but the mornings are where it’s at.

The standout of the whole run has to be Tuesday, July 7th morning. We’re looking at a 4ft SW swell with an 18-second period. The combined energy jumps to 1279 – that’s moderate but pushing into strong territory, meaning there’s some real grunt in the water. But the kicker is the glassy, offshore wind from the ENE. This is excellent, powerful wave conditions for experienced surfers. The 4ft is a healthy size, maybe a touch much for total beginners, but for anyone with a bit of time in the water, this is the morning to circle.

Wednesday the 8th continues with a clean 4ft SSW swell in the morning and an offshore breeze from the ENE (991 moderate energy). Thursday the 9th is similar with a 4ft SW swell and offshore NE winds. The energy settles back to moderate (624).

The second week is still offering fun waves, but with less overall consistency. Friday the 10th through to Monday the 13th mornings are mostly glassy or with light offshore winds, but the swell drops back into the 2ft to 3ft range and the period shortens to 13–15 seconds. The energy is in the weak to moderate range (200s–500s). The exception is Thursday the 16th morning, which is flat calm and glassy with a 3ft SSW swell, giving a clean wave but nothing powerful.

So to wrap it up: for the best quality and power, you cannot miss the Tuesday the 7th morning session. But if you want silky, clean longboard waves, the Saturday the 4th and Monday the 6th mornings are your ticket.

Stay stoked,
Rusty.

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.
