As a rule, one may ride, walk or loaf outdoors, without fear of overexertion. The air is like wine, it builds one anew.

Yet the weather is not perfect. You may strike a small sandstorm in midsummer. You may hit a blizzard in midwinter. A torrential shower may drench you. A fervent sun may unduly tan you. But these deviations from Paradise come only occasionally; they are the bitter that makes the sweet more sweet.

I can safely promise you, nine times out of ten, pleasanter weather than you would find if at home. And that is the best test.

Rest-cure. Those who visit the Canyon oftenest and stay longest find the least fault with its weather. For myself, I never complain; rather I always look forward with great joy to an outing here. For besides being an unparalleled scenic spectacle, the Grand Canyon is the greatest of rest-cures. I know of nothing better for tired nerves and worn-out bodies than to summer or winter along its rim, and down below where the river runs.

Because the weather one year never is like the year before or after, I cannot accurately forecast what you will find of heat or cold, wet or dry, when you visit the Canyon. Even the "weather man" is not infallible in his predictions. I only can outline a reasonable average, resting upon observations made during a score of years.
