Castelhanos Surf Spot Guide, Brazil

Nestled on Brazil's stunning Ilhabela, Castelhanos delivers a raw beach-break experience with punchy rights and lefts peeling over a sandy bottom, perfect for those craving uncrowded lines in a pristine paradise. This exposed spot fires up with east swells, offering experienced surfers long, powerful rides amid lush Atlantic Forest vibes that feel worlds away from the mainland hustle. It's the kind of place where you paddle out to solitude and score sessions that linger in your memory.

Geography and Nature

Praia dos Castelhanos sits on the rugged east coast of Ilhabela, an archipelago just 6 kilometers off São Paulo's coast in the Atlantic Ocean, forming part of a mountainous main island that peaks over 1300 meters high. This remote beach stretches wide with fine sand, backed by dense tropical rainforest and framed by steep cliffs, creating a wild, isolated feel reachable mainly by rugged 4x4 roads. The landscape is untouched and dramatic, with the ocean-facing shore exposed to swells while the interior hides hiking trails through pristine Atlantic Forest.

Surf Setup

Castelhanos is a classic beach break firing both rights and lefts, with waves that can barrel on the right and wall up nicely on the left when east swells roll in from distant groundswells. Offshore winds from the west clean it up best, providing some shelter from southerlies, while high tide is prime as it enhances the sandy peaks and keeps sections rideable. Expect a typical session to deliver consistent, powerful waves up to 2 meters on good days, with fairly reliable surf that rewards positioning and commitment from experienced paddlers.

Consistency and Best Time

Surf at Castelhanos is fairly consistent year-round thanks to its exposed nature, but winter months from June to October bring the most reliable east swells and cleaner conditions, making it the peak season for scoring. Avoid summer from December to March when swells often go flat and onshore winds dominate. Spring and fall offer transitional swells with fewer crowds, ideal for mid-sized days around 1-1.5 meters.

Crowd Levels

This spot stays empty even when waves are firing, with minimal presence on both weekdays and weekends. You'll share lineups sparingly with a mix of locals and visiting surfers.

Who It's For

Castelhanos suits experienced surfers who can handle powerful beach-break waves and read shifting sandbars effectively. Beginners should steer clear due to the steep takeoffs and potential for 2-meter faces, while intermediates might catch smaller days but will find it challenging overall. Advanced riders thrive here, linking sections for long rides in empty lineups.

Hazards to Respect

Watch for strong rips that can pull you out on bigger swells, and note the spot's isolation means help might be delayed. The sandy bottom keeps it forgiving, but always surf with a buddy.

Water Temperature and Wetsuit Guide

Summer from December to March sees water temperatures around 23-25°C, so boardshorts or a rash vest suffice to block UV. Winter from June to October drops to 20-22°C, calling for a shorty or thin spring suit for comfort. Spring and fall hover at 21-24°C, where boardshorts work fine but a shorty adds protection on longer sessions.

How to Get There

Fly into São Paulo's Guarulhos International Airport (GRU), about 170 kilometers from Ilhabela, or the closer São José dos Campos Airport (SJK) roughly 100 kilometers away, then drive or bus to São Sebastião port for a 20-minute ferry to Ilhabela. From the island's port at Vila, rent a 4x4 vehicle for the essential 20-kilometer dirt road trek over steep hills to Castelhanos, which takes 1-2 hours and requires high clearance. Parking is available near the beach entrance; no public transport reaches here directly, so plan for self-drive or guided 4x4 tours, with the break just a short walk from drop-off points.
