The best time to visit Port Jervis is during the summer and autumn months, from June to October, when the weather is most pleasant for outdoor activities.Summer, particularly July and August, offers warm temperatures great for enjoying the Delaware River. This is an excellent time for families looking to spend time outdoors, perhaps kayaking or tubing on the river, or exploring the local parks. The days are long, allowing for extended exploration of the natural surroundings.For couples or those seeking a scenic escape, autumn, from September to October, is particularly appealing. The foliage around Port Jervis and the surrounding Upper Delaware River Valley transforms into a spectacular display of colours.
