One of the signature moments of the Evian Championship’s trophy ceremony comes when a parachutist descends onto Evian Resort Golf Club’s 18th green to drape the flag of the winner’s home country around her shoulders.

On a few recent occasions, no one would have blamed the new champion for pulling the flag a little tighter around her — for warmth.

Though the tournament’s September date had given it the distinction of being the year’s final major championship on any tour, it came with the risk of getting hit by capricious weather as seasons changed in Évian-les-Bains in the French Alps, where the tournament is held — and not enough daylight to weather a storm delay to complete play.

In two of six Septembers, heavy rain prompted L.P.G.A. officials to shorten their newest major to 54 holes. A 2017 playoff between Anna Nordqvist and Brittany Altomare was contested amid freezing rain and hail.
