“Every year there are too many unusual tragedies that take place during summer vacation”
There is a high correlation between ice cream consumption and violent crime. Both peak in the summer months. Does that imply causality. Likewise, there is a substantial increase in accidental deaths related to drownings, hiking, climbing boating etc. during the months of Tamuz and Av. In both cases, obviously the time of year is linked to these events and without dismissing hashgacha paraatis, there is absolutely nothing “unusual” about a spike in such tragic accidental deaths on a particular summer day.
