The prime months for golf in St Andrews are April through September, when temperatures are mild (typically 50–65°F/10–18°C) and courses are in their best condition. July and August offer the warmest weather but also see the most visitors and highest prices, especially if major tournaments are scheduled. April, May, and September are considered shoulder season, providing better value, fewer crowds, and generally good playing conditions, though weather can be more variable with occasional rain and wind. Outside these months, courses remain open but expect colder temperatures, more frequent rain, and shorter daylight hours, which can impact play.
