About this spot

About

Blonde Reef is an exposed reef break inside Hilo Bay on Hawaiʻi’s Big Island, known for relatively consistent surf. Multiple sources describe the wave as often soft and mushy, which tends to make it more forgiving and suitable for longer lines (including longboard-style sessions) when the swell is properly lined up. Swell works best from the northeast (with reported optimal directions including NE/northeast), and the spot’s character is strongly tied to wind direction. Offshore SW winds are described as grooming the waves, while NE tradewinds can blow the wave out—so conditions can shift noticeably over the course of the day. Wind tends to follow a diurnal pattern typical of the Hilo windward coast: lighter morning land breezes followed by onshore trade winds in the afternoon. Wind is reported as mixed overall with moderate reliability and moderate gustiness, while typical wind speeds are described in a lighter-to-moderate range. Safety is the key constraint at Blonde Reef. It is a reef break with submerged reef/rocks plus hazards including urchins and sharks. The paddle out is long, and local guidance emphasizes avoiding sessions after heavy rain because runoff can reduce water quality and may increase shark activity. Lifeguard presence is indicated as none at the spot, so plan for self-rescue readiness and avoid marginal conditions.

  • Consistent exposed reef-break surf in Hilo Bay
