Lightning Strike Frequency Map

Within 30 seconds the red dot fades to yellow, and the yellow fades to brown and disappears within one hour. Areas with the fewest number of flashes each year are gray and purple; The lightning strike density maps cover the geographic area from 25 degrees south to 80 degrees north latitude and from 110 degrees east to 0 degrees west longitude.

Times are expressed in coordinated universal time (utc). The high lightning areas are on land located in the tropics. This system offers the most accurate lightning detection available for the uk.

Times are expressed in coordinated universal time (utc).

When lightning strikes it sends out pulses of radio waves and these can be used to detect lighting strokes. The interval between maps is 10 minutes. Images are updated every 15 minutes with a 15 minute delay due to processing. Areas with the largest number of lightning flashes—as many as 150 per year per square kilometer—are bright pink.
