September in Baja California Sur is a time of transition. The summer heat is still here, but the pace slows down. If you are planning boat trips Los Cabos, this guide will tell you exactly what to expect.
Why Visit Los Cabos in September?
Most people don’t realize that September brings some of the best opportunities for relaxation. The spring break crowds have vanished. The winter snowbirds haven’t arrived yet. It is just you, the locals, and the Sea of Cortez.
If you are wondering what Los Cabos in September feels like, picture long, lazy days and incredible value. Resorts often drop their rates. Flights are usually cheaper. You can get a table at the best restaurants in Cabo San Lucas without a reservation.
The vibe is laid-back. You don’t have to rush to save a beach chair. You can take your time. If you want a luxury experience without the peak-season price tag, this is the time to book a private Cabo San Lucas yacht rental. You get the same stunning views of Land’s End, but with more privacy and calm surroundings.
Los Cabos Weather in September: What to Expect
Here is the honest truth about Los Cabos weather in September. It is warm.
The sun shows up early and stays late. You will feel the humidity more than in months like January or February, but that is what the ocean is for. The Pacific breeze helps, especially in the evenings.
- Average Daytime Highs: Around 32℃ – 34℃ (90℉ – 93℉).
- Nighttime Lows: Comfortable near 24℃ (75℉).
- Water Temperature: The warmest of the year, often reaching 29℃ (84℉).
Daily Forecast and Rain Patterns
September is technically part of the hurricane season, but don’t let that scare you away. Rain usually comes in the form of “chubascos”—fast, intense showers that pass quickly.
The clouds often build up in the late afternoon. They might release a refreshing shower for twenty minutes, and then the sun breaks through again. It rarely ruins your plans. In fact, these showers wash the dust off the desert, making the Sierra de la Laguna mountains look greener than any other time of year.
Best Days for Outdoor Adventures
Because of the heat, the best strategy is to plan your outdoor activities for the morning or late afternoon. The middle of the day is perfect for a long lunch under a palapa or a siesta.
Early mornings are magic. The water is often glass-calm. This is the prime window for paddleboarding near the Arch or heading out on a fishing charter. By 5:00 PM, the heat breaks, and the sunsets are spectacular.
Key Events and Festivals in Los Cabos in September
September isn’t just about quiet beaches; it is a month of national pride.
- Mexican Independence Day (September 16) This is the biggest event of the month. On the night of September 15th, you will hear “El Grito” (the cry of independence) in the town squares of San Jose del Cabo and Cabo San Lucas. Expect fireworks, mariachi music, and plenty of tequila. It is a fantastic cultural experience that most winter tourists miss.
- Day of the Mexican Air Force (September 18) While smaller than Independence Day, you might see aerial displays or local ceremonies honoring the military. It adds a local flavor to the week.
- Fishing Tournament Prep While the massive Bisbee’s Black & Blue tournament is in October, the energy starts building now. Anglers are out scouting the waters. If you are into sportfishing, booking a private Cabo fishing yacht charter in September puts you on the water before the tournament madness begins. You have less competition for the best spots at the Gordo Banks.
Top Things to Do in Los Cabos in September
When looking for things to do in Los Cabos in September, look toward the water. The ocean is your best friend this month.
1. Beach Hopping and Water Sports
September offers the warmest ocean temperatures of the year, averaging a balmy 29℃ (84℉). This makes beach days absolutely incredible. You can float for hours at swimmable spots like Medano Beach without ever feeling a chill, or explore the protected marine sanctuaries at Chileno Bay where the waves are gentle. Since the crowds are thin, you will easily find a prime spot on the sand. For those wanting to see more of the stunning coastline, our shared catamaran Cabo San Lucas tours are the perfect choice. You can enjoy music, open bars, and guided access to the most pristine bays, all while soaking up the vibrant atmosphere of the Baja summer.
2. Snorkeling and Fishing at Their Best
Underwater visibility is at its peak in September, often exceeding 50 feet. The Sea of Cortez teems with life during this warm season. You might spot schools of colorful tropical fish, playful sea lions, and even sea turtles near the reefs. Because the winds are generally calmest in the morning, early excursions are ideal. To truly experience this underwater magic without the distraction of other groups, we recommend booking a private catamaran Cabo San Lucas snorkeling tour. Your captain can navigate to secluded coves that larger boats cannot reach, giving you exclusive access to the vibrant marine life and a peaceful environment for your family to explore safely.
3. Sunset Cruises and Day Trips to the Arch
There is a unique beauty to September evenings that you won’t find in winter. The lingering clouds from afternoon showers create a dramatic canvas for the setting sun, painting the sky in intense shades of violet, gold, and fiery orange. The humidity drops, leaving a fresh, comfortable breeze. There is no better way to witness this spectacle than on a private catamaran sunset cruise Los Cabos tour. As you sail past the iconic Arch at Land’s End, the golden hour light makes for unforgettable photos. It is an intimate, romantic experience perfect for couples or close friends looking to toast to another perfect day in paradise.
