Sunrise above the clouds on Maui, then live volcanoes on the Big Island. Early July falls in Hawaii's dry season, giving good odds for clear volcano and summit viewing, but the Haleakalā summit (10,023ft) is a different climate zone entirely — expect near-freezing pre-dawn temperatures at sunrise even in summer, with wind chill, so pack real cold-weather layers despite the tropical island setting. Lower elevations at both parks run warm and humid, upper 70s–80s°F, with brief afternoon showers more likely on the Big Island's windward side. Plan for an inter-island flight mid-trip.
