We at The Cabo Sun love Cabo in September—it’s warm, a little wild (hello, tropical season), and full of local color.
But it’s also different from winter-peak Cabo.
If you’re planning a trip next month, here are the 5 biggest things to know so you can set expectations, score value, and have an amazing time.

1) Yes, it’s peak storm season—plan smart, don’t panic
September sits right in the heart of the Eastern Pacific hurricane/rainy season.
That doesn’t mean your week turns into a washout; it does mean you should book flexible rates, add travel insurance that covers weather, and keep an eye on official forecasts.
The good news: Cabo resorts take preparedness seriously—local authorities even certified 11 Cabo San Lucas hotels as Temporary Safe Shelters this season, a nice bit of peace of mind if weather rolls through. We also see occasional high-surf days driven by offshore systems; when that happens, lifeguards raise red/black flags and some water activities pause for a day or two.

2) Expect hot, humid, “pool-first” weather
Daytime highs typically hover around the low 90s°F (32–34°C) with warm nights—aka prime pool and spa time.
Plan outdoor hikes, golf, or marina strolls early or late; keep midday for shade, ceviche, and a nap.
Water temps are bath-warm, so snorkeling feels fantastic when surf cooperates.

3) The ocean is beautiful—but choose swimmable beaches and read the flags
Cabo’s #1 rookie mistake? Assuming every postcard-perfect beach is swimmable. Strong Pacific currents make many stretches “look-don’t-touch.”
Stick to locals’ favorites—Medano, Chileno, Santa Maria, and Palmilla—all highlighted in our first-timer’s guide to swimmable beaches and in tourism officials’ picks for top beaches.
Blue Flag sites add extra lifeguards and amenities; our explainer on Cabo’s Blue Flag beaches is a great shortcut for safe, clean spots.
And if conditions spike (mar de fondo, storms at sea), heed the beach flags and lifeguards—no photo is worth a rip current.

4) It’s the quiet season—fewer crowds, good value…with a few quirks
Historically, late summer/September is Cabo’s “less busy” window.
You’ll often find better room values than winter, easier last-minute tables, and a calmer vibe around the marina. The flip side: a handful of restaurants and outfitters use September for brief maintenance breaks or staff vacations—so double-check hours and have a Plan B dinner pick.
Divers and snorkelers get a bonus: warm water and visibility are excellent at regional hotspots like Cabo Pulmo in September.

5) September has a very local vibe—don’t miss Independence Day and turtle releases
If you want “real Mexico” moments, mid-September delivers.
On Sept. 15–16, Los Cabos lights up for Fiestas Patrias with the mayors’ Grito de Dolores, mariachi, and fireworks—this events guide flags the best ways to join in.
Expect festive energy in plazas, rooftop bars, and along the marina. Meanwhile, late summer is sea turtle season; several resorts host evening hatchling releases you can participate in (respecting conservation rules, of course).
It’s magic. Start with our event primer and this round-up of turtle programs at local resorts.

Quick trip hacks we use ourselves
- Pick your “home beach” first, then your hotel. If daily swims are non-negotiable, book on or near Medano, Chileno, Santa Maria, or Palmilla, and browse our Blue Flag explainer before you commit. Our guide to the best-of beaches, by traveler type is a handy cheat sheet, too.
- Watch surf forecasts during your dates. If a system stays offshore, you may just see bigger sets and temporary red flags—plan a spa day or taco crawl, then get back in the water when flags drop. Our recent high-surf advisory breaks down what to expect.
- Be flexible, win big. Because September is “less busy,” you can often upgrade views, grab last-minute boat charters on calmer mornings, and snag promos like extra-night-free or pivot to a cooking class on stormy afternoons.
If you take one thing away: September in Cabo rewards the traveler who plans smart and stays flexible.
Pack the sunscreen, add that travel insurance, bookmark our swimmable-beach guide, and come ready for warm water, local fiestas, and those technicolor Baja sunsets.
