About lightning in Greece
Greece's thunderstorm season peaks in autumn. From September into December, cool air moving over a still-warm Aegean and Ionian sea fires intense, sometimes flooding storms along the coasts, the islands and the western mainland, while the mountains add summer afternoon convection. Athens and Thessaloniki see fast-building storms that strike ahead of the rain. The live distance to the nearest flash and whether it is closing in are the safer guide than a seasonal average.

Lightning safety in Greece
When storms build across Greece, the distance to the nearest strike matters more than a country-wide count. Follow the 30-30 rule: if thunder follows lightning by 30 seconds or less, get indoors, and wait 30 minutes after the last thunder before heading back out. StrikeCast surfaces the live distance and trend so you can act before the storm reaches you.
