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 ProfileMecánica de la Ola (Ola de Punta (Point Break)): Las series de mar de fondo de largo periodo (10s+) sufren refracción inmediata al contactar la plataforma volcánica submarina, concentrando 45 kJ de energía en la zona de despegue sin cerrar en barra. El canal adyacente drena el agua con fluidez sin arrastrar a los surfistas a la zona de impacto.
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
