Half Moon Bay Beach in Winchester Bay is generally not recommended for swimming due to strong currents, cold water temperatures, and unpredictable waves typical of the Oregon coast. The beach is better suited for wading, tidepooling, and beachcombing. Always supervise children closely near the water. The sandy beach and sheltered location make it excellent for building sandcastles and playing in shallow areas. Check local conditions before visiting, and never turn your back on the ocean as sneaker waves can occur unexpectedly along the Oregon coast.

Half Moon Bay Beach is accessible year-round, with each season offering different experiences. Summer (July-September) provides the most stable weather with less rain and occasional sunny days, though coastal fog is common. Spring and fall offer fewer crowds and good opportunities for storm watching and wildlife viewing. Winter brings dramatic waves and stormy skies, perfect for beachcombing after storms. Temperatures remain mild year-round (45-65°F), but wind and rain are common. For family beach activities, late summer typically offers the calmest conditions and warmest temperatures.
