In August you can get by with just a nice lightweight wind jacket that also has a hood and some layer of protection for added warmth. We're talking only about a pound here or less. Just make sure to check the weather forecast (as mentioned above) before you head up.

I hike in mid to late September and so I also bring along an extra sweater and pants (and gloves and a cap). Altogether they weigh about 3 pounds.
