can you let me know what is the whether like during early and late August.

The temperature is 62.6 F to 86 F. It's not so hot. And during this period of time, it mainly contains cloudy and sunny days. Short-sleeve T-shirts are enough for you to take. Or take an extra thin coat for the night. The possibility of rainy days is low. So it won't influence your travel activities. Don't worry.
