Castlerock

Castlerock is a well-known surf spot on the north coast of Ireland, often grouped with the North East / East-facing Atlantic coastline depending on how spots are being categorized. It sits beside the village of Castlerock in County Londonderry, near the mouth of the River Bann.

Spot overview

• Type: Beach break with some sandbank variation
• Exposure: Open to Atlantic swell, especially from the northwest to west
• Best winds: Easterly or southeasterly offshore winds
• Wave character: Can be fast, powerful, and hollow when sandbanks line up well
• Skill level: Best for intermediate to advanced surfers, though smaller, softer days can suit improvers

Conditions

Castlerock can produce good quality waves on the right tide and swell direction, with shifting sandbars creating peaks and sections along the beach. Because it’s a beach break, conditions can change quickly after storms or big swell events.

Swell and tide

• Swell direction: Works best on N to W/NW swell
• Tide: Often best around mid tide, though this can vary with sand movement
• Bottom: Sandy, so the setup changes frequently

Hazards

• Strong currents, especially on larger swells
• Closeouts when sandbanks aren’t well aligned
• Can get crowded on good days
• Exposed coastal conditions mean weather can change rapidly

General vibe

Castlerock is a classic Irish surf beach: scenic, punchy, and inconsistent in a way that rewards patience. When it’s working, it can offer fun, peeling waves in a very exposed Atlantic setting.
