The best time to visit Cabo San Lucas depends on your preferences and what you hope to experience during your stay. The peak tourist season runs from November through April when the weather is pleasantly warm but not exceedingly hot. This period also coincides with whale-watching season when visitors can witness the magnificent migration of humpback whales along the coast. Alternatively, those seeking quieter times may consider visiting during the shoulder seasons (May to June and October) when the weather is still pleasant, and hotel rates often decrease.
