Cabo San Lucas Weather in September

September feels hot and damp

September is one of Cabo San Lucas's toughest months for outdoor sightseeing. Days feel hot and sticky, with warm nights that offer little relief. Rain falls on several days, and tropical storms can bring rough seas or disrupt plans. It's wetter than August and much wetter than October.

You can still enjoy a shaded lunch around the Marina or browse the shops in downtown Cabo. But long walks in the midday heat and fixed boat plans are less appealing. The Arch is best seen when sea conditions are calm, so keep your plans flexible.

Mexican Independence Day

September 16 is Mexican Independence Day. Cabo joins celebrations across Mexico, with a public gathering called El Grito, music and fireworks. The exact programme can vary, but the holiday brings a lively evening around town.

Families may prefer a relaxed dinner near the Marina, then a short look at the celebrations. The heat and rain can be a lot for young children, so keep outdoor plans simple.

Quieter, but with trade-offs

September is low season in Los Cabos. You'll often find fewer visitors and better hotel deals than during the busy winter months, when many people come for dry weather. Some businesses may have reduced hours, and stormy weather can affect boat trips and fishing. If you dislike heat, November to June is a more comfortable time to visit.

For a Cabo boat outing, ask your operator about its cancellation policy before heading to the Arch. If the sea is rough, don't push for the trip; enjoy a meal of fish tacos back on shore instead.
