Rain in Al Jumum: What You Need to Know
Al Jumum is a governorate north of Jeddah, known for the Fatma Wadi that has produced notable flash-flood events in the wider Makkah region. Jeddah's average annual rainfall is just 83mm, but almost none of it falls evenly -- the wet season (November-April) can deliver more in a single afternoon than the rest of the year combined.
Rain is driven by the Red Sea Trough, a low-pressure system that pulls moist air off the sea and forces it up against the Sarawat mountain range running parallel to the coast just east of the city. That mountain range creates a sharp orographic effect: air is forced upward on the Jeddah side, condenses fast, and can dump extreme rainfall in hours -- 182.0mm fell at Jeddah Janub in a single day in November 2022, more than double the city's average for an entire year.
