The mornings of August 12th and 13th and 14th: midnight to dawn - look out for the Perseid meteor shower.
If clear, these mornings should give us a chance of observing the Perseid meteor shower - produced by debris from the comet Swift-Tuttle. The peak of the shower is after sunrise on the morning of the 13th so the early morning of the 13th August will give us the best chance, if clear, of viewing the shower, but the peak is quite broad and so its well worth observing on the nights before and after. Most meteors are seen looking about 50 degrees from the "radiant" which lies between Perseus and Cassiopeia. The great thing about this year is that, with New Moon on the 14th, there will be no moonlight to hinder our view in the days around the peak. Under cloudless skies and from a dark location observers might expect to see 50 to 70 meteros an hour near the peak (the last hours of darkness on the morning of the 13th).
