The Ryder Cup starts relatively early, usually in late September, primarily because organizers consider factors like the overall golf calendar, weather conditions at the host venue, and avoiding clashes with other major sporting events. The timing aims at favorable weather and peak conditions for play and viewership, making late September an ideal period for this biennial competition.
More specifically for the 2025 Ryder Cup, it begins on September 26, following this traditional late September window. This timing allows for operational readiness, including pre-tournament activities that start even weeks before the matches, such as team gatherings and practice events, which contribute to the early start of official Ryder Cup activities.
Weather considerations can occasionally cause slight shifts, like moving ceremonies earlier, but the late September start remains consistent to balance climate, player schedules, and maximizing global audience attention.
