So summer (for me) temperatures! Sounds good.The weather varies a lot. One year it will be, say, 10°C and rainy and another 25°C and sunny. I've gone through snow in the Appalachians on the way home (sonot sticking on the ground snow, but falling snow none-the-less), and I've worn shorts on the trip out. Highs average around 15°C. It usually isn't humid that time of year unless it is raining. My usual packing: light jacket, perhaps bring a pullover. You probably aren't going to go out of the hotel much anyway.

Given my wife will be coming too, i suspect i will be spending more time outside than most.
