Electric Beach Hazards

Electric Beach (Kahe Point Beach Park) sits on the dry western coast of Oʻahu, directly adjacent to the Hawaiian Electric power plant. The warm water discharge from the plant’s cooling system flows into the ocean near the beach, attracting an unusual concentration of marine life including spinner dolphins, green sea turtles, and large schools of reef fish.

The warm discharge plume creates a visible current flowing outward from shore. Snorkelers should be aware that this current can move them into deeper water. The reef drops off steeply on the south side of the beach, and the bottom terrain is irregular with lava formations, sand channels, and coral heads.

The best entry point is the small sandy channel near the center of the beach. Avoid entering over the lava rocks on either side, where surge can sweep you off your feet. Fins are strongly recommended for both propulsion and protection against the rocky bottom.

Winter (November – March)

West side conditions are typically calm during winter since the large north swells primarily affect north and east-facing shores. However, strong Kona (southwesterly) storms can generate significant surf along this coast, producing 4–8 foot waves that make the rocky entry extremely hazardous. Water temperatures remain warm year-round near the discharge pipe (78–82°F). Winter mornings are often glassy and calm, providing the best diving and snorkeling visibility.

Summer (April – October)

Generally calm with occasional south swells that produce 1–3 foot waves. Trade winds create afternoon chop but rarely generate dangerous conditions on this west-facing coast. Spinner dolphins are most frequently spotted during summer mornings as they rest in the warm, shallow waters near the discharge. Snorkeling conditions are best before 10 AM. The power plant operates year-round, maintaining the warm water outflow that attracts marine life.

Weak swimmers and snorkelers: The outflow current from the power plant can pull you into deep water. Stay close to shore and within sight of the sandy entry point. If caught in the current, swim perpendicular to it (parallel to shore) rather than fighting directly against it.

Solo visitors: With no lifeguards and a rocky shoreline that makes re-entry difficult, snorkeling alone here is particularly risky. Always bring a buddy and inform someone on shore of your planned route.

People unfamiliar with ocean entry over rocks: Timing your entry between wave sets is essential. Watch for several minutes before attempting to cross the rocks, wear sturdy reef shoes, and never turn your back to the ocean while on the shoreline rocks.

What are the biggest dangers at Electric Beach?

Strong currents from power plant outflow. Deep water close to shore. No lifeguards. Not for beginners.

Does Electric Beach have lifeguards?

No. Nearest hospital: Pali Momi Medical Center (20 mi). Cell phone coverage: Moderate.

What are conditions like at Electric Beach in winter vs summer?

Winter: Large swells can make entry/exit dangerous, strong surge. Summer: Calmer entry, warm water from plant outflow attracts marine life including dolphins and turtles

Who should be cautious at Electric Beach?

Non-swimmers, solo divers, anyone unfamiliar with ocean currents. The warm outflow creates unpredictable currents that can push swimmers out to sea.
