The table above shows temperature and humidity conditions for Everglades National Park, which is in a large swamp-wetlands ecosystem, and Las Vegas, Nevada, which is in the vast Mojave Desert. The temperature range is based on average monthly high and low temperatures. The humidity value is based on the overall average humidity.

If most other swamps and deserts follow patterns like these, then deserts generally have temperature ranges and humidity levels than swamps.
