Expect sunshine 350 days a year in Cabo due to its desert climate and the Californian Gulf breeze. Winter months average in the mid 70's, while summer months can get just above 100 degrees, so pack accordingly and don't forget floppy hats, sunglasses, and sunblock. Evenings do cool off significantly due to less humidity. The best time to visit Cabo is from May to June after the bird migration, but before the hurricane season. If you're into whale-watching, plan to visit between December and March, and if you wish to go fishing, plan for the late summer or fall.
