Between August 26 and August 28, 2026, Hailstorm Raphaela caused an unprecedented €3.296 billion in insured losses across France, Germany, Switzerland, and Italy. This event stands as the costliest convective storm on record for PERILS, impacting both motor and property sectors.
Why it matters
The record-breaking loss total highlights the increasing financial risk posed by severe convective storms fueled by extreme heat and humidity. These multi-billion-euro events are increasingly viewed as the new normal for the European insurance market.
The storm produced hailstones reaching 13cm in Italy, while other affected regions saw typical diameters ranging from 4cm to 8cm. These impacts culminated in the largest single catastrophe loss ever recorded for the Swiss insurance market.

The details
A powerful low-pressure system and cold front collided with warm, humid air left behind by previous heatwaves to create intense rotating supercells. This atmospheric combination caused widespread damage to vehicles and properties throughout the four-country region.
Timeline
August 26-28, 2026: The convective storm event Raphaela took place.
July 2026: A separate convective storm outbreak occurred.
November 28, 2026: An updated loss figure for the storm is expected.
January 1, 2027: Annual insurance contract renewals are scheduled.
Seasonal Patterns
This storm follows a pattern set by the July 2026 convective storm outbreak by establishing a new record for insured losses in a single event. It indicates a shifting landscape where multi-billion-euro storm damages are becoming a consistent seasonal outcome.
Property owners and motorists in affected regions should review their coverage policies ahead of the January 1, 2027 renewal period. Understanding how insurers account for convective storm damage is critical given the recent record-breaking losses.
The takeaway
The Raphaela event underscores the rising economic volatility associated with severe convective weather in Europe. Residents should prepare for potential premium adjustments or coverage changes as insurers adapt to these high-loss events.
What happens next
An updated loss figure for the Raphaela storm event is scheduled for release on November 28, 2026.
