Weather at Trimmer Campground

Best Time to Camp at Trimmer Campground

Best season: fall. Fall offers the best balance of mild daytime temperatures (typically 60–85°F) and cool, crisp nights (40s–50s), making lakeside camping, boating, and hiking comfortable without summer heat. Pine Flat Lake is quieter after the peak summer crowds and fishing often improves as the water cools; oak and pine slopes take on warm autumn tones. Fire danger and extreme heat decline compared with summer, so access and trails are more reliable while weekend crowding is moderate rather than intense. Peak months: October, September, November, April

About Trimmer Campground

This small lakeside spot offers flush toilets, hot showers, and direct access to a foothill reservoir popular for water sports and angling. Rangers maintain the grounds during the seasonal operating window, and campers appreciate the combination of developed amenities and proximity to the water.
