I'll be the first to welcome you to Albuquerque. I can't really help with your question since I live here and have not camped on the balloon fiesta grounds. I would guess that any time around noon would be good since everything is pretty much over by 10am or so. The weather is not looking very good for later in the week. The balloons went up on Saturday and today but did not go up yesterday. Wednesday and Thursday look like the best days this week for good weather. Rain is forecast for next weekend but hopefully it will just be showers in the afternoon. I hope you have a great time.
