Nearly all of the Negev is an extremely arid desert that sees rainfall at most a few times a year. While winters can be pleasant, with temperatures hovering around 20°C, summers can be fierce with temperatures commonly over 40°C, but in the afternoon and at night there is a comfortable temperature drop. The climate in the Negev is dry without hardly any humidity. Bring a large amount of water and register your plans at the nearest police station before going offroad for your own safety, as flash floods are likely to happen if rain does fall, and some parts of the Negev serve as the IDF's main training area.
