I went in December, so I can’t help you much. I’ve heard it isn’t so bad in June. 50’s and 60’s I think.

Enjoy! It’s a fabulous experience.

I went in July and the nights were very moderate until the 3rd night near the summit. There, it got cold enough that the condensation turned to ice on our tent. Like any mountain trip wear layers, making sure one is fleece or equivilant. If you sleep cold, have your guide fill your water bottle with hot water and stick it at the footbed of your bag. It does wonders.

Good luck and enjoy.

I agree with the above.

The weather is very cold. Make sure that your sleeping bag is down and very warm—there is nothing worse than being cold while you sleep. Warm socks are essential—don’t be afraid to splurge on a really good pair. During the day you’re hiking so you don’t have to worry about the cold as much…

You are about to have the best adventure! Have fun!

In the mountains, every day is aseason. Winter thru the night, spring in the morning, summer in the afternoon and fall in the evening.

We started our hike in early July. Great time of the year to go. You can go to weather.com for the seasonal averages, both rainfall and temperature. Layers are a must. The days were mostly very warm, shorts and t-shirt type of hiking, but the evenings and early mornings it was chilly. Invest in good hiking boots and hiking pants with a removable lower leg and consider taking your own sleeping bag or at least your own insert. Also, my wife found her hiking poles to be invaluable, in particular on the down parts of the trail. The climb to the summit was very difficult, but worth every moment.
