This month marks the beginning of the peak season, which extends through July, and you'll find the weather pleasantly warm, with temperatures typically ranging from the mid-50s to low 70s Fahrenheit. May's mild climate offers ideal conditions for outdoor activities, making it a fantastic time to explore the lake's stunning surroundings, hike nearby trails, or simply enjoy a scenic picnic by the water's edge.
As you plan your journey, keep in mind that the vibrant colors of the lake and its picturesque landscape are particularly captivating in spring. You'll have the opportunity to witness the blooming wildflowers and lush greenery that enhance the area's natural charm. The pleasant weather and longer daylight hours make it superb for a range of outdoor pursuits, from kayaking to photography.
