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 ProfileDinamika Ombak (Tanjung Berbatu (Point Break)): Garis alun berperiode panjang (10dtk+) langsung membiaskan saat menyentuh paparan vulkanik bawah laut, memusatkan energi ombak 45 kJ ke area takeoff sementara ombak mengelupas rapi. Saluran arus di sampingnya mengalirkan air dengan lancar tanpa menyeret peselancar ke zona tubrukan.
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
