If you're planning outdoor time in Amman, altitude is the variable most travelers miss. At 1,000m, the city is cooler than you'd expect for its latitude. I hiked the citadel in July expecting desert heat — got a manageable 28°C with low humidity. The data shows summer is genuinely pleasant: 26°C, near-zero rain. The challenge is winter: January averages 8°C and snow falls every few years, paralyzing the hilly streets. Spring (March-May) and autumn (September-November) are the outdoor sweet spots: 16-22°C, low rain, clear air. UV is intense at altitude — sunscreen mandatory even on hazy days. The Roman Theatre steps are brutal in midday summer sun; go early.
