The Long Beach Peninsula is at its best in spring (April and May) and early autumn (September and October). Summer brings the most visitors but also persistent marine fog that can keep the beach grey for days at a time; the Peninsula averages roughly 60 inches of rain a year, most of it falling between November and March. Autumn storms rolling in off the Pacific are dramatic and the beach is emptier.
Razor clamming runs from October through April on WDFW-designated open days at low tide — check the Washington Department of Fish and Wildlife website before visiting if this is your purpose. The Cranberry Harvest Festival in Ocean Spray in October is one of the larger local events. Kite festivals draw crowds to Long Beach in summer; the town holds a world record for the longest kite chain.
Winter visits have real appeal for anyone who likes wild weather and empty beaches. Most restaurants and shops in Long Beach stay open year-round, but hours shorten considerably outside the summer season.
