The attire is semi-formal evening dress. However, the grass is soft and the paths are dirt, so we recommend wearing shoes that are easy to walk in, and that you won't mind getting a little dirt on.
Yes, the venue is all outdoors, so please bring a sweater or light jacket for the evening. We will have some heat lamps and blanket's available, depending on how cool the evening gets.
Average temperatures in Pala, CA in mid June are in the high 80's during the day, and the low 60's during the evening. There is a ton of shade from the trees and a light breeze, since the venue is on a hill. So the weather should be warm but comfortable during the ceremony/cocktail hour. And a bit cooler during the evening.
