Thunderstorms can occur almost everywhere on Earth, but they are most common in warm, humid regions, especially over land in the tropics and mid‑latitudes.

Quick Scoop: Where Do Thunderstorms Occur?

  • Thunderstorms happen on every continent , including North America, South America, Africa, Europe, Asia, and Australia.
  • They are most frequent in tropical and temperate regions , where warm, moist air rises easily to form tall storm clouds.
  • Equatorial areas of Africa and South America can have thunderstorms on well over 100–180 days per year in some locations.
  • At any moment, there are roughly 1,800–2,000 thunderstorms happening somewhere on Earth.
  • Thunderstorms are rare near the North and South Poles because the surface air is too cold and dry to support strong updrafts.
  • Over the oceans, storms do occur, but landmasses get more thunderstorms because land heats up faster than water, boosting rising air and convection.

Regional Examples

  • In the United States , thunderstorms occur in all 50 states, but are most common in the Southeast and Gulf Coast (especially Florida), and also over parts of the Great Plains and Rockies.
  • In tropical rainforest zones (for example parts of central Africa, Amazonia, Southeast Asia), thunderstorms may happen nearly daily in the wet season.
  • Cities such as Kampala (Uganda), Bogor (Indonesia), Singapore, and others near the equator are often cited among the most thunderstorm‑prone places on Earth.

Why These Places?

  • Thunderstorms thrive where three ingredients come together:
    1. Warm air at the surface.
    2. Plenty of moisture (humidity).
    3. A trigger to make air rise (strong sun heating the ground, mountains forcing air up, or fronts where air masses collide).
  • Tropical land areas near the equator check all three boxes, which is why they see so many storms, while polar regions and cool, dry areas see very few.

Tiny Story Snapshot

Imagine a muggy afternoon in a tropical city near the equator. The sun has baked the ground all day, warm air is bubbling upward like water in a pot, and within an hour towering clouds grow into a booming thunderstorm right over town—just one of hundreds happening around the planet at that same moment.

TL;DR

Thunderstorms can form almost anywhere, but they mainly occur over warm, humid land in the tropics and mid‑latitudes , and are uncommon near the poles and in cold, dry regions.
