I don't know about August , but I was just there at the beginning of this month and it was upper 80's in the mountains. However there was plenty of water in Boot Spring. It was running throughout. Also they have gotten a lot of rain this last two months. But certainly carry enough to get you through. If you are gonna camp with a tarp, I highly suggest Deet or some other repellant, the mosquitos and flies were abundant! You'll be in the rainy season so watch for afternoon thunderstorms and lightning. Also I would suggest hiking up Pinnacles trail rather than Laguna, as you rise through the elevation faster and reach campsites a lot quicker. Just my $.02. Have a great trip!
