With warm summer weather coming to Lake Tahoe and bringing mid to high 70°F days on average during the month of June, it is easy to see why this is one of the most popular times of year to visit. June is considered the start of the summer season, and that means visitors wanting to visit the Lake Tahoe area will want to book in advance, preferably at least 3 months ahead, to ensure availability at any hotels, attractions, and rentals they may want to enjoy. The warm weather opens up access to swimming and boating on the lake as well as spending relaxing time on the beaches, hiking in the surrounding woods, and mountain biking in the nearby mountains.
