Cabo in September: Weather, Crowds & Is It Worth It?

Is September a Good Time to Visit Cabo?
Yes, with a caveat. Cabo San Lucas in September typically offers the warmest ocean water of the year, thinner crowds, and hotel rates that are often noticeably lower than winter peak pricing. The trade off is humidity, a real chance of afternoon downpours, and a hurricane season that peaks this exact month.
If you want a lively beach party scene with zero weather risk, September is not your month. If you want value, warm water for diving and fishing, and don’t mind flexible plans, cabo san lucas in september is one of the smartest times to book.
Weather in Cabo in September: The Real Numbers
Most articles say “it’s hot and rainy” and move on. Here’s what the weather in Cabo in September actually looks like, broken down by what matters to a traveler.
Temperature & Humidity
- Daytime highs: Around 90 to 91°F (32 to 33°C). This is the same range as July and August, so September doesn’t cool things down yet.
- Nighttime lows: Around 75°F (24°C). Evenings stay warm and humid, so pack light fabrics rather than layers.
- Humidity: High, typically in the mid to high 70 percent range. This is what makes September feel hotter than the thermometer suggests.
Ocean & Water Temperature
Around 83 to 84°F (28 to 29°C), typically the warmest of the entire year. This is one reason some divers, snorkelers, and anglers consider weather in september cabo san lucas worth planning around rather than avoiding.
Rainfall & Sunshine
How Much It Actually Rains
September is typically the wettest month in Cabo, with rainfall commonly cited in the range of 3 to 4 inches for the month. Rain tends to fall on a limited number of days rather than continuously, and it’s often described as short, intense afternoon or evening downpours rather than all-day rain. Mornings can often be clear, though this varies by year.
Sunshine Expectations
September generally still sees a fair amount of sunshine overall. It’s not an even split between sun and rain; most days lean sunny with the occasional heavier storm.
The honest summary: cabo in september is hot, humid, and unpredictable in short bursts, not a month of constant bad weather.
Hurricane Season: What You Actually Need to Know
September sits at the peak of the Eastern Pacific hurricane season, which officially runs from mid-May through the end of November.
How Real Is the Risk
Many tropical systems that form off the Pacific coast weaken or track away from the Baja peninsula before making landfall, and a number pass at a distance that brings mainly rain and wind rather than a direct hit. That said, Los Cabos has been affected by hurricanes and tropical storms in past years, so a direct or near-direct impact, while not typical, is a real possibility during this period. It’s worth checking current conditions and forecasts as your travel dates approach rather than assuming the risk is zero.
How Resorts and Forecasters Prepare
Resort Storm Protocols
Many hotels and tour operators in the region have experience operating through tropical weather and may adjust, delay, or reschedule activities when conditions require it. Exact policies, cancellation terms, and preparedness vary by property, so it’s worth confirming directly with your hotel or operator.
Advance Warning
The U.S. National Hurricane Center and Mexican meteorological authorities track and publish forecasts for developing systems, which can give travelers some advance notice as a storm approaches. Storm paths and intensity can still shift with relatively short notice, so it’s worth monitoring official updates in the days before and during your trip rather than relying on early forecasts alone.
How to Protect Your Trip
Given the timing of hurricane season, travel insurance is worth considering for a September trip. A policy with hurricane coverage or “cancel for any reason” coverage can help offset the cost of changes, which may be particularly relevant for weddings or once-a-year trips.
A practical approach is to build some flexibility into your itinerary, avoid scheduling anything irreplaceable for a single fixed day, and check the forecast in the days leading up to your trip. This won’t eliminate weather risk, but it can make it easier to adjust if conditions change.
Crowds, Prices & Availability
September is generally considered one of the quieter months in Los Cabos, along with other wet-season months. That tends to come with some practical upside:
Often Lower Prices
- Hotel rates can be lower. Resorts that charge premium rates in the December through March high season often lower their rates during September to attract bookings, though exact discounts vary by property and how far in advance you book.
- Flights can be more affordable. Airfare to Los Cabos International Airport can be cheaper during shoulder and low season months, including September, though pricing varies by airline, route, and timing.
A Quieter, More Relaxed Cabo
- Restaurant reservations may be easier to get. Popular spots that require booking well ahead during winter can have more short-notice availability in September, though this isn’t guaranteed everywhere.
- Beaches can feel less crowded. Médano Beach, which is often busy with vendors and sun loungers during peak season, can feel noticeably calmer in September. If exploring the beaches in Cabo is part of your trip, September can offer a more relaxed experience at some popular spots.
If your goal is a relaxed, less commercial version of Cabo, and you’re comfortable trading some weather certainty for potential savings, September can work in your favor.
What You Can Actually Do in Cabo in September
Warm water changes the activity list. If you’re researching things to do in Cabo San Lucas, September still offers plenty of options, particularly for travellers who want to spend time on or around the water. Here’s what actually gets better this month, not worse:
Water Activities That Peak This Month
- Scuba diving and snorkeling. Warm ocean temperatures make for more comfortable, longer time in the water without a wetsuit. Visibility depends on conditions rather than temperature alone, and can be reduced on days with rain or runoff, so it’s worth checking current conditions with a local operator.
- Sport fishing.September is often cited as a strong month for sport fishing in the region, with marlin, dorado, and tuna among the species anglers commonly target this time of year. If you’re comparing the best time to fish in Cabo, September can be particularly appealing for anglers looking for warm-water fishing opportunities. Cabo Magic offers sport fishing charters out of Cabo San Lucas, with options suited to both first-time anglers and experienced ones looking to fish this time of year.
- Marine life encounters. The Sea of Cortez is known for its marine biodiversity, and sightings of various sea life can occur near the coast, though wildlife encounters are never guaranteed.
Low-Key Activities Suited to September
- Spa and resort days. With fewer guests, spas, pools, and beach clubs are noticeably calmer and easier to enjoy without crowds or waitlists.
- Evening activities. Sunset cruises and rooftop dinners work well since the heaviest rain tends to arrive in short bursts, and evenings often clear up quickly.
For anglers planning around seasonal conditions, it can also be useful to compare Cabo fishing seasons before choosing your travel dates, as the species and fishing opportunities can vary throughout the year.
What gets harder: long, uninterrupted beach days without any rain risk, and outdoor weddings that don’t have a covered backup plan.
What to Pack for Cabo San Lucas in September
- Lightweight, breathable fabrics (humidity makes heavier clothing uncomfortable fast)
- A packable rain jacket or poncho for sudden downpours
- Reef-safe sunscreen, since UV stays strong even under cloud cover
- A dry bag for phones and electronics near the water
- Sandals with grip for wet tile and sudden showers
- A light layer for air-conditioned restaurants and evening breezes
Who Should (and Shouldn’t) Visit Cabo in September
Go if you’re:
- A diver, snorkeler, or angler chasing peak warm-water conditions
- Traveling on a budget and want access to higher-end resorts at often lower prices
- Comfortable with humidity and the occasional rescheduled excursion
- Looking for a quieter, less touristy version of Cabo
Wait for another month if you’re:
- Planning an outdoor wedding with no rain contingency
- Traveling with someone who is heat- or humidity-sensitive
- Not comfortable with any hurricane-season uncertainty in your travel plans
- Set on nonstop guaranteed sunshine every single day
Final Verdict
Cabo in september rewards travelers who value warm water, low prices, and a quieter Cabo over travelers who need a guaranteed picture-perfect week. The heat and humidity are real, and so is the chance of a sudden afternoon downpour, but neither one defines the month the way people expect.
What actually defines cabo san lucas in september is the trade off: fewer crowds on the beaches, easier restaurant reservations, often lower hotel and flight prices, and typically the warmest ocean water of the year for anyone who dives, snorkels, or fishes. Travellers who want to explore different places to visit in Cabo San Lucas while keeping their itinerary flexible can still enjoy plenty of options during the month.
A reasonable approach is to pack a rain jacket, consider travel insurance, keep at least one day in your schedule flexible, and lean into morning activities when skies tend to be clearer. This won’t guarantee perfect weather, but it can help you make the most of a month that, for many travelers, offers a calmer and less commercial version of Cabo than peak winter season.
