Winter Months. From late in November to the end of April, snow may be expected at any time on the rim, though many of the most delightful days of the year occur in these months. Snow usually does not fall until after Christmas. Some years the winter is almost snowless; other years there is enough snow to make fine sleighing. June and July are the warm summer months, with August hot; but the heat is likely to be tempered by the rain. From the middle of July to about the end of October, rains may be looked for at any time, and the days after the rains are generally cool, delicious and altogether desirable. Now and again, both before and after a rain, the air will be moist and sultry, somewhat as it is in the East, but this condition is so rare as to cause surprise. Generally the air is dry, and the sun shines warmly, so that "catching cold" is infrequent.

Late Fall Most Pleasant. In my varied experience at the Canyon, I have found the months of September, October, and November most agreeable in spite of an occasional hot day in September. January and March are often perfect months, and while there may be a little (or much) snow on the rim, I regard the winter as the most delightful time for trips into the Canyon. The snow may make the trail slippery and disagreeable for the first mile or so, then one reaches the dry and snowless region where, practically, snow never falls, yet where the heat from radiating rock walls is tempered and subdued by the coolness from the snow above.
