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 ProfileDinamica dell'Onda (Punta Rocciosa (Point Break)): I treni di maretta a lungo periodo (10s+) subiscono un'immediata rifrazione a contatto con la piattaforma vulcanica sottomarina, concentrando 45 kJ di energia sulla sezione di takeoff srotolando in modo pulito. Il canale adiacente drena l'acqua senza risucchiare i surfisti nella zona d'impatto.
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
