Mid-September to mid-October, or April–May. Comfortable temperatures between 67–83 F, lower crowd levels than peak summer, and all major attractions fully open. Spring also coincides with San Isidro festivities. WeatherSpark notes 'the best time of year for hot-weather activities is late June to late August,' but for comfortable sightseeing the shoulder seasons are preferred
