Night temperatures in Canaima (Kavak) in June?

Slept in Canaima in august once, a bit chilly but ok with the blankets. Just improvise with your clothing if you're cold, would not say there's a need to bring a sleeping bag.

I also spent a few days in Canaima and around Salto Angel in mid-July. During the day the weather was fine and it was quite warm. At night, it got a little bit cold, but not too much. I used the blankets offered by the camp and it was fine. One day I used the hammock the cover me up, as there were no more blankets avaible in the camp.. I think you will be fine without a sleeping bag.. but bring a sweater just in case..

Thanks for your advise!
