About lightning in France
France runs two lightning regimes. Inland and over the mountains, summer heating from May through August sets off afternoon thunderstorms, while the Mediterranean south sees its most violent storms in late summer and autumn, when warm sea air feeds intense, slow-moving cells that can dump a month of rain in hours. Because these storms strike fast and often ahead of the rain, the live distance to the nearest flash — and whether it is closing in — is what keeps you safe.

Lightning safety in France
When storms build across France, 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.
