Surf Conditions Guéthary Parlementia Today — Score 9.1/10 and Weather Analysis

Today at Guéthary Parlementia is shaping up to be a genuine stand-out session. We're looking at a maximum score of 9.1/10—the kind of day that separates the weekend warriors from committed surfers willing to wake before dawn. The swell is sitting at a solid 2.9m with a period of 12.15 seconds, which is the critical ingredient here. That 12+ second period means the waves are genuinely spaced apart and carry real energy. This isn't choppy beach break slop; this is organized Atlantic swell with proper drive behind it. The wind condition—a light 5.3 km/h from the ESE—is playing directly into Guéthary's hands, and we'll explain exactly why in the technical breakdown below. The timing couldn't be better for the early risers. The best wave window opens at 07h00 with a score of 9.0/10, meaning you'll lose virtually nothing by getting on it at first light. For a spot on the French Atlantic coast that regularly delivers quality waves, today represents the upper tier of performance—the kind of condition you mark in red on your calendar and text your crew about the night before. Across the day, the average swell holds at a respectable 2.5m, so even if you can't make the dawn patrol, mid-morning and early afternoon remain thoroughly rideable.

🕐 Best session windows

Your absolute best window is 07h00—first light—when the score peaks at 9.0/10. This timing is critical for two reasons: tide state and wind consistency. At dawn, the tide mechanics are typically in transition (either pushing toward low or recovering from it), and more importantly, the ESE wind is at its lightest and most offshore before thermal and pressure-driven winds build through the morning. By catching the dawn session, you're surfing into a window where that 12.15-second swell is maximally organized and the wind isn't yet onshore. If you're not a dawn person, don't worry—the overall score only drops to 9.1/10 maximum across the day, meaning the bulk of your daylight hours remain premium. However, avoid the late afternoon when thermal sea breezes typically clock onshore and break down wave definition.

📊 Detailed weather analysis

The 2.9m swell with a 12.15-second period is the mechanical foundation of today's excellence. Period is everything in surf forecasting. A 12-second period means the wavelength is enormous—roughly 225 meters between wave centers. This translates to waves that don't crumble immediately; they hold their shape, march in organized sets, and offer proper wall for turning. Contrast this with a typical 8-second chop, and you understand why today scores 9.1 instead of 5.0. The swell direction at Guéthary is being refracted and shaped by the underwater bathymetry of the Basque coast, but the period length ensures that energy transfer to the beach break remains consistent throughout the tide cycle. The wind condition—5.3 km/h from ESE—is functionally offshore for Guéthary Parlementia's west and northwest-facing exposures. An ESE wind (East-South-East) means the air is moving from the land toward the Atlantic, which holds the wave faces clean and prevents the onshore chop that destroys rideability. This is a light offshore, not a howling gale, which is precisely what you want—enough to groom the swell without flattening it or creating hazardous conditions. The combination of a long-period, properly-wound swell meeting a clean offshore breeze is textbook premium Atlantic coast surfing. The 2.5m average throughout the day suggests that even as the tide shifts and wind potentially nudges onshore in the afternoon, the fundamental wave quality remains accessible.

📍 About the spot

Guéthary Parlementia sits on the Basque coast's western flank, a region known for consistent Atlantic exposure and reliable swell capture. The spot's topography—both the underwater reefs and the beach bank geometry—naturally amplifies swell organization. The ESE wind today is working optimally with this exposure: because the land mass is to the southeast, an ESE wind is a true offshore, pushing air away from the water surface. This spot benefits from both Atlantic groundswell (multi-day fetch originating from storm systems far west) and local wind-swell generation. Today's 12.15-second period suggests groundswell dominance, meaning the fetch originated days ago from a proper depression system. This is not local wind-generated noise; it's mature, organized swell that has traveled and consolidated. The spot's sandy/reef composition means it holds shape across different tide states, making it forgiving for surfers of varied abilities while remaining challenging and rewarding for experts seeking performance.

❓ FAQ

What time is best to surf at Guéthary Parlementia today?

07h00 is your golden hour, with a score of 9.0/10. This is first light, when the ESE wind is offshore and the 12.15-second swell is maximally organized. The overall daily score only reaches 9.1/10, so the morning into early afternoon remains excellent, but avoid late afternoon when thermal winds typically turn onshore and compromise wave quality.

What is the surf score at Guéthary Parlementia on 26/10/2026?

The maximum score is 9.1/10, with the best window at 07h00 scoring 9.0/10. This reflects the combination of 2.9m swell, 12.15-second period (exceptional for Atlantic coast standards), and a clean 5.3 km/h ESE offshore wind. A score this high means well-formed waves, consistent sets, and excellent rideability across multiple tide states.

Are conditions improving this week at Guéthary Parlementia?

Today and Wednesday 28th are the standout days, both scoring 9.1/10. Tuesday drops to 7.7/10 as the current swell weakens, but a new fetch brings Wednesday's rebound. Thursday through Saturday progressively deteriorate to 5.4/10 lows, with minimal swell and likely onshore wind. If you can only surf twice this week, choose Monday dawn and Wednesday. Sunday shows the beginning of recovery (6.5/10), suggesting better conditions next week.
