Weather in May

May has pleasant temperatures and starts the tourist season earnestly in Pennsylvania as spring spreads its wings fully. The average high temperatures are in the warm 65°F (18.3°C) to 75°F (23.9°C) range, while the average low temperatures are in the mild range of 40°F (4.4°C) to 50°F (10°C). Harrisburg, the capital of Pennsylvania in the east, has average temperatures in the comfortable 51°F (10.6°C) to 72°F (22.2°C) range, while Jamestown in the west is between a mild 45°F (7.2°C) to warm 68°F (20°C).
Most of the snow melts in the highlands, and upper mountain ranges by May and rainfall of 4" (102mm) to 5" (127mm) adds freshwater to the water bodies that come roaring down the hills.
Sunshine makes a glorious comeback by May as spring becomes noisy amid the cacophony of birds and animals. Watch out for black bears and other animals that desperately hunt for food after facing a shortage during the winter, especially, while exploring the state parks or the mountain trails - a bear spray is a proven accessory to carry on hikes!
