The best time of year to visit St Andrews is during the summer months (June to August) when the weather is warm and sunny, and the town is bustling with tourists. However, this is also the busiest time of year, and hotels can be expensive. Spring (March to May) and autumn (September to November) are also great times to visit, with fewer crowds and milder temperatures. Winter (December to February) is the least busy time of year, and hotels can be cheaper, but the weather is often cold and rainy.
