According to French state-owned network France 24, Macron said coronavirus risks made it "impossible" to allow winter sports to resume quickly.
He said he would consult with European partners to co-ordinate start dates for the winter season and promised an update in 10 days.
Macron said to plan for a re-opening of the resorts in January "under favourable conditions".
France 24 reports health authorities have warned that regional hospitals could be saturated quickly if crowds of skiers from France and abroad were allowed to travel to certain regions.
France has 350 ski resorts employing 120,000 people during the high season.
