May is a wonderful spring month in Washington with warm weather. The average high temperatures are in the pleasant 58°F (14.4°C) to 68°F (20°C) zone, while the nights are mild in the average range of 35°F (1.7°C) to 45°F (7.2°C). Chirping birds, regular spotting of wildlife in the natural preserves, fresh aroma of flowers, fresh water in the lakes and rivers, and the warmth of the sun enlighten the spirit. Biking, hiking, kayaking, and fishing are quite enjoyable in comfortable weather. The sunshine improves significantly, but occasional arctic cold fronts can push down the temperatures briefly. The warm sun pushes the rain and snow to the background. The warm ocean waters bring hordes of whales to the west coast of Washington. The visitor footfall increases with the beginning of the tourist season. May is an excellent time to visit Washington to beat the summer crowds in the pleasant spring weather. Wear warm clothes as the sunshine is moderate.
