Moab home base — Delicate Arch at sunset, Island in the Sky at sunrise. Late May in Moab brings warm, dry, high-desert conditions: daytime highs climbing from mid-70s toward low-80s by month's end, overnight lows high-40s to low-50s°F — comfortable for hiking but with intensifying midday sun exposure on shadeless slickrock trails. Precipitation is low, but afternoon winds can pick up dust across exposed viewpoints; plan strenuous hikes for early morning or near sunset.
