We did the day hike on 9/3, the switchback streams seemed to be flowing a bit more in the afternoon than in the morning, but I would fill up further down the hill.....away from the Trail camp pond. The temperature in the valley was in the 90's, at the Portal it was in the 80's. Starting early in the morning, I was comfortable in a wicking t shirt by 1000. On the summit around noon, it seemed to be in the mid 60's, sunny and breezy, not too hot or too cold.
