About Constitución

Constitución is a coastal city in central Chile, located at the mouth of the Maule river, known for its extensive beaches and consistent waves. It is a good destination for intermediate surfers looking for quality waves without the crowds of the more famous spots, in a setting shaped by the meeting of the river and the sea. Its beach breaks offer peaks with lefts and rights over a sand bottom, with conditions that improve with south swells. One of its great natural icons is the Piedra de la Iglesia and the rock formations surrounding the area, a unique landscape that gives character to the coast. The best season runs from autumn to winter, between April and August, and the cold water makes a wetsuit advisable. For the surfer traveling the Maule region, Constitución combines consistent waves, singular scenery and a quiet atmosphere away from the bustle.

Condition Scoring

Rating Algorithm 1-10

Each forecast hour receives a score from 1 to 10, calculated by adding points for different factors:

Wave Height (0-4 pts)

< 0.5m = 0 pts | 0.5-1.0m = 1 pt | 1.0-1.5m = 2 pts | 1.5-2.5m = 3 pts | > 2.5m = 4 pts

Dominant Period (-1 to 3 pts)

Uses the dominant/peak period (wave_period). < 8s = -1 pt (wind swell, messy) | 8-10s = 0 pts | 10-12s = 1 pt | 12-16s = 2 pts | > 16s = 3 pts

Wind (-2 to +2 pts)

Glassy (< 5 km/h): +2. Light wind (5-10 km/h): +1. Moderate wind (10-20 km/h): offshore +1, onshore -1. Strong wind (> 20 km/h): onshore -2, offshore -1. Wind data covers the full 15-day forecast window.

Secondary Swell (-1 to +1 pt)

If a secondary swell with height ≥ 0.3m and long period (≥ 10s) exists, +1 point is added. If the period is short (< 10s) and direction differs > 45° from the primary swell, -1 point penalty for crossed seas. If directions are similar (≤ 45°), no penalty is applied.

Rating by score:

Flat (1) Poor (2-3) Fair (4-5) Good (6-7) Epic (8-10)
