Ask Me: What Clothing Do You Recommend for August in the High Sierra?

Hi Michael,

I have been enjoying your adventure posts immensely; keep up the great work!

I lead hikes for the local chapter of the Sierra Club in Tucson, and in mid-August we’ll be doing a 7-day backpacking adventure in the High Sierra. We’ll be accessing the John Muir Trail, with elevations ranging from 9,000 to 12,000 feet. How cold can it get at this time of year and what clothes/protection would you recommend? Would a light windbreaker over a fleece with gloves and hat be sufficient? Or would you recommend a down jacket, etc.?

I’d appreciate your feedback!

    Hello Michael,

    Thanks for sharing this info! I tend to be a minimalist in terms of trail clothes (and in terms of many other things) so this post brought a couple more questions to mind. For the High Sierras in mid-August…

    > In the evening, is it chilly enough that you advise an alternate base layer (to switch with a sweaty base layer)?
    > Do you think most people would want an extra lower-body layer (Merino or capilene leggings) for around camp?
    > So you would carry a rain shell, but not rain pants?
    > Btw, how cold is that water you’re swimming in? Really, I’m curious! You mean a quick dip, or…?

    Thank you.

    Loving “The Big Outside”

      Hi Laura, glad you love The Big Outside! All good questions. I carry minimalist clothing, too, usually one synthetic T-shirt and one long-sleeve, midweight top. I tend to only wear the long-sleeve if I hit the trail early and it’s cool, and switch to the T-shirt once I start warming up; so I avoid getting the warmer top all sweaty and I can use it as a warm layer in the evening in camp (and wear it sleeping if needed). When I arrive in camp in a sweaty T-shirt, I wear it while setting up camp, with a rain jacket over it if I need a little warmth or wind protection, so that my body heat dries out the T. I’ll also sometimes wear the slightly damp T over my long-sleeve in the evening to dry it for the morning’s hike. That’s how I typically avoid carrying more than one of each.

      People who need more than just pants in temps in the 40s and 30s may want an extra lower-body layer in camp. I don’t get cold too easily, so I don’t carry that extra layer in summer.

      The High Sierra isn’t a very rainy place in summer. I may eat those words someday, but yes, I carry a lightweight rain jacket but not rain pants, which I find too warm to hike in, anyway. However, I like low gaiters with lightweight pants to keep my boots and socks dry in rain, snow, and mud, and I recently reviewed lightweight, zip-off, soft-shell pants that don’t make me overheat, repel light rain, and dry fast:

      Mountain lakes vary quite a bit in how cold they are, depending on depth near shore (deep water doesn’t warm up much, but shallow water can be very comfortable by August), elevation, and whether it’s being fed by a nearby snowfield. So it could be frigid and only tolerable for a quick dip, or warm enough for a longer swim.

    Hey Mitch, I hope you are aware that basically from Bishop north past Yosemite is totally smoked out because of 2 wildfires. These fires have altered my up coming plans in the Sierras but fortunately it’s a big place and can options are plentiful.
