About
Sun Beach (Oarai) is a very expansive, sandy coastline with clean water and shallow surfable conditions that make it especially approachable for learning—particularly for beginners on the surf side. Multiple sources describe the beach as “vast” and note that surrounding coastal structures (sea dikes / breakwater influence) can reduce the impact of larger waves, helping keep the water more manageable near the beach area. The beach-break surf tends to be gentle and low-energy, with soft, mushy waves that peel slowly, which suits longboard and beginner progression. For wind sports, the spot is recognized for kitesurfing with working wind reported from NNE through SE. Sources also emphasize that the most consistent wind component is from the Northeast, while noting that summer thermal can sometimes be weak—meaning foil kites or other setups may be needed when wind is marginal. For wind reliability, spring and autumn are highlighted as better windows due to more consistent frontal-system conditions, while summer brings bigger crowds and more swimmers. Seasonal conditions matter here. Water temperature is described as cool in winter and comfortable through summer (with the coldest months around February and the warmest months around August). Wind-focused travel is often framed around spring and autumn for more reliable conditions, while summer is mainly favored for surfing and family beach time. Crowd intensity is also strongest in July and August. Safety-wise, be mindful of swimmers during the official summer period and follow the designated sport-zone restrictions for kiteboarding. Hazard zones can include the sea-dikes/breakwater influences and tetrapods/wave breakers at the ends of the beach, and in some conditions onshore wind can push beginners toward seawalls. Check tide timing—at low tide the beach can become very wide, creating a longer walk and (for foiling) requiring enough water depth before committing offshore.
- Very wide sandy beach with easy launch and lots of space
- Beginner-friendly surf due to shallow, gentle beach-break waves and protective dike/breakwater influence
- Kite wind directions reported from NNE through SE; Northeast is often most consistent
- Spring and autumn often provide more reliable wind compared with summer thermal variability
- Extremely wide sandy beach with easy launch and ample space
- Beginner-friendly shallow water for learning (notably surf)
- Working wind directions span NNE through SE for kitesurfing
- Sea dikes/port structures can reduce the impact of larger waves for beginners
- Thermal wind can be weak in summer afternoons, requiring appropriate equipment (often foil)
- Swimming season restrictions and swimmers during peak summer
- Very shallow water means learning/foiling requires careful water-depth management at low tide
- Chop potential from NE winds can affect surfing

- Beach Size
- Big
- Waves
- Medium — Wave size described as medium in some physical summaries; surf is also described as small/gentle overall for beginners.
- Chop Level
- Light chop — NE winds can create significant chop for surfing, while overall surf power remains soft.

Through the year
Extremely crowded with tourists in July and August; quiet during weekdays in off-season.
Typhoon season peaks in August and September; June is the primary rainy season.
By sport
What to expect for each.
Wide sandy beach with very shallow water and lots of launch space; working wind reported from northeast through southeast. Some sources describe it as beginner-friendly, while others note intermediate ability for kites in practice depending on conditions.
- Kite Sizes
- 9–15 m²
Suitable for freeride and foil, particularly during NE winds.
- Sail Sizes
- 5.5–7.5 m²
Popular due to shallow launch and lack of shore break, but riders must walk out deep enough for foil-safe depth; a minimum walk out distance is noted at low tide.
- Foil Friendly
- Yes — Foil friendly per spot-level source.
- Min Depth
- Walking out 50-100 meters required at low tide to reach foil-safe depth
- Wing Sizes
- 4–6 m²
Very popular beach-break for beginners and longboarders with gentle, slow-breaking conditions over a sandy bottom; sea dikes and port breakwater influence reduce the force of larger sets near the beach ends.
- Wave Direction
- Both
- Optimal Swell
- E, SE
- Swell Height
- 0.5–1.5 m
- Optimal Tide
- Mid — Mid tide noted as optimal.
- Shelter
- Exposed — Exposed coastline overall; however, sea dikes/port structures can lessen impacts from high waves in the immediate beach area.
- Wind Effect
- NE winds can create significant chop; winds from W or SW are described as offshore and can groom the waves.
- Bigger Swell
- When swell exceeds about 2 meters, waves can close out across the beach.
- Wave Quality
- Average — Average wave quality; beach-break character tends toward mushy waves.
- Wave Power
- Soft — Soft wave power overall; sea dikes reduce the impact of larger waves.
- Wave Shape
- Mushy — Mushy/low-energy character, often gentle for learners.
- Peel Speed
- Slow — Gentle, slow-peeling waves.
- Ride Length
- Medium — Consistent rides; often mushy with slow peeling.
- Ride Length Details
- Consistent but can be mushy; peels slowly over flat sand.
