Lightning is not evenly distributed. Satellite data from NASA's lightning imaging sensors has mapped every strike on Earth for three decades, and the result is a map with a few extremely bright spots on it — places where the geography traps warm wet air against cold air night after night, and the sky discharges hundreds of times an hour, most of the year.
The best of them is Lake Maracaibo in Venezuela, where the Catatumbo river meets the lake. Warm air off the water hits cold air spilling down from the Andes, and the collision produces storms on roughly 260 nights a year, sometimes for nine hours at a stretch with 28 flashes a minute. Sailors used it as a lighthouse. Most of the strikes are cloud-to-cloud, which is why you can watch it from a distance in relative safety.
What makes this worth travelling for rather than watching from a window at home is the near-certainty. You are not waiting for a storm — you are booking a place where the storm is a nightly institution. The rules that come with it are simple and non-negotiable: watch from indoors, from a boat cabin, or from a vehicle, never from open water or a ridge, and treat every "safe distance" claim with suspicion. Lightning kills a few thousand people a year, and it concentrates in exactly these places.
Where on Earth it's best

★ Signature spotCatatumbo — Lake Maracaibo (Ologá, Congo Mirador)VenezuelaThe highest lightning density on Earth — about 250 flashes per square kilometre per year, on roughly 260 nights, concentrated over one corner of one lake. Warm Caribbean air is funnelled into the Maracaibo basin and hits cold Andean downdraughts from three mountain ranges at once, and the storm regenerates over the same spot night after night. You watch it from stilt villages built out over the water, so the entire sky is unobstructed and the strikes reflect off the lake beneath them.The topography does it: three cordilleras funnelling into a warm inland sea. Nothing else on Earth is arranged this way. Strongest September to November, weakest in the January–March dry season. Storms build after dark and peak around midnight. 2
Lake Victoria basin — Ssese Islands & Kampala shoreUgandaSatellite analysis ranks the Lake Victoria basin as the most lightning-prone large region on Earth, and a 2016 NASA-led study put several of its shorelines above Catatumbo on flash-density-per-area for parts of the year. Storms roll in off the lake at night with a wall of light behind them. The two rainy seasons — March to May and October to December — with almost nightly storms. 3
Kifuka & the Congo basinDR CongoThe eastern Congo held the world record for lightning strikes per square kilometre for years before Maracaibo was recalculated, and the basin as a whole remains the most electrically active landmass on the planet. Storms are near-continuous through the year, peaking in the wet seasons. 4
Hector the Convector — Tiwi Islands & DarwinAustraliaA thunderstorm so reliable it has a name and a first name. Sea breezes from both sides of the Tiwi Islands collide over the middle every afternoon in the build-up season, producing a 20 km-high cumulonimbus at almost the same time each day — pilots used it as a navigation mark in the Second World War. September to March, the "build-up" and wet season. Hector forms in the afternoon and is visible from Darwin across the water. 5
BogorIndonesiaKnown in Indonesia as Kota Hujan, the rain city — Bogor records over 300 thunderstorm days a year, more than almost anywhere, driven by moist air rising against the Salak and Gede volcanoes. Year-round, heaviest October to April. Storms are an afternoon institution rather than a night one. 6
Singapore & the Strait of MalaccaSingaporeOne of the highest lightning rates of any city on Earth — roughly 170 thunderstorm days a year — with the "Sumatra squalls" crossing the strait before dawn and the whole skyline lit from behind. April–May and October–November are the peak inter-monsoon months; squalls arrive between 4 and 8 a.m. 7
Córdoba & the Sierras de CórdobaArgentinaSouth America’s storm laboratory. The RELAMPAGO field campaign came here because the Sierras generate some of the tallest thunderstorms measured anywhere, and the WMO’s record for the longest single lightning flash — 768 km — was set over this part of the continent. The southern storm season, November to March, with storms building over the sierras in late afternoon. 8
The Great Plains — Nebraska to west TexasUnited StatesThe clearest storm structure in the world. Dry air off the Rockies caps humid Gulf air until it explodes upward, producing isolated supercells you can see whole from 50 km away — a rotating tower lit from inside. Late April to mid-June, moving north through the season.
