Contreiras & Ribeira da Janela — Reef Mechanics, Channels & Wind Shadow
Two complementary setups side by side: surf low tide on the long left at Ribeira da Janela (up to 2m), then transition to Contreiras as the tide pushes from mid toward high.
HYDROGRAPHIC REFRACTION, TAKEOFF & EXIT CHANNEL PROFILE
Beach & Reef Bottom ProfileDynamique de la Vague (Vague de Pointe (Point Break)) : Les trains de houle longue (10s+) subissent une réfraction immédiate au contact du plateau volcanique sous-marin, concentrant 45 kJ d'énergie sur la zone de take-off tout en déroulant proprement. Le chenal adjacent évacue l'eau avec fluidité sans aspirer les surfeurs vers la zone d'impact.
PERSONAL SESSION NOTE: Contreiras works from mid-tide to high-tide (reference session: 10 kt, NNW 331°, 3.6m swell — enter 2 hours before high tide and exit 50 minutes before full high tide). Ribeira da Janela works best at low tide and holds up to ~2.0m.
- •At Contreiras, strictly exit 50 minutes before peak high tide
- •Strong rip current toward the sea stack on swells > 3.0m
- •Shifting river-mouth boulders on exit
