The best time to visit Lowell is during the warmer months, particularly from late May to early October, when the weather is pleasant and many local events are in full swing.For those who enjoy outdoor activities and local festivals, the summer months of June, July, and August are ideal. The average temperatures are comfortable for exploring the Riverwalk or enjoying the Flat River. This period also sees the most community events, such as the Lowell Showboat Sizzlin' Summer Concerts, offering free live music along the river.If you prefer slightly cooler weather and the beauty of autumn foliage, September and early October are excellent choices. The changing colours along the Flat River are quite scenic, and the apple orchards in the surrounding area are open for picking, providing a pleasant experience for families and couples.
