The best time to visit Greenville, California, is during the summer and early fall, specifically from June through September, when the weather is warm and dry.These months offer ideal conditions for enjoying outdoor activities around Lake Almanor and the surrounding Plumas National Forest. You can expect pleasant temperatures for hiking, fishing, boating, and exploring the scenic beauty of the region. This period is particularly good for families looking to take advantage of the lake's recreational opportunities, with plenty of sunshine for swimming and watersports.For those interested in a quieter experience and enjoying the changing foliage, late September and early October also offer beautiful scenery as the leaves begin to turn.
