Add Heading HereI had a pretty good hike at San Jacinto. We hiked up at about 2 mph, stayed up top for about 15 minutes, took pictures, and camped at 9800ft. Hiked back down the next day.
Temp was about 90 at the bottom. By the time we got to the top, the temp was probably about 65...not too windy.
Night got chilly, but not too bad.
