Sounds like you know what you're doing. I usually have a long sleeve white shirt, light colored pants, and a big hat. The point is to keep the sun off you. Of course it's better to be where there are lots of trees, which I guess are hard to come by at Lake Havasu.

Missouri weather in the summer is as variable as it is at any other time of the year. Some days it will be 75 and pleasant, others will be 105 with oppressive humidity. On days like that if you must be outside, you don't do much. Of course canoeing down a remote Ozark steam shaded by 200 foot bluffs can beat the heat.
