The best time to visit Pennsylvania is from the end of April to the end of June. The state sees rather drastic weather conditions which make for a small window of time where other weather conditions like rain and snow are minimal. Temperatures range between 60F to 69F. However, apart from this time period, Pennsylvania observes four distinct weather seasons that offer up a different experience to tourists. Spring in Pennsylvania runs from May to March. These months see humidity and temperatures within the range of 42F to 78F, making for a cooler climate. Summer in Pennsylvania is the busiest time of the year for tourism. Temperatures range from 69F to 73F and although these months receive most of Pennsylvania's rainfall, it is restricted to about 5 to 6 days per month. Fall and winter receive much colder weather. Temperatures range from 46F to 80F in September to November and tourism during this month stalls a bit, making accommodation prices drop. High winds and snow hit Pennsylvania during its winters.
