The best time to visit Santa Rosa is during the dry season, which runs from October to May, offering warm, sunny days superb for exploring.For those looking to enjoy the pleasant weather without the peak season crowds, November and May are ideal. These months still offer excellent conditions for outdoor activities like hiking and beach visits, but with fewer tourists, you'll find a more relaxed atmosphere and potentially better value on accommodation and experiences.If you're particularly interested in marine life, the cooler months from December to April are best for whale watching, as grey whales migrate to the warmer waters of Baja California Sur.
