Cabo San Lucas in October (2026): Warm Sea, Easing Storms & Big-Money Marlin Tournaments

⭐ Best October window: the second half of the month. Late October pairs easing storm risk and settling weather with warm water and the energy of the Bisbee's tournaments. Early October is cheaper but still carries more of the summer's storm odds.

Cabo San Lucas in October is the turn back toward the good season. The heat and humidity start to ease, storm risk drops through the month, and the warm sea sticks around, all while prices stay in friendly shoulder-season territory. It is also peak big-game fishing, capped by the world-famous Bisbee's marlin tournaments late in the month. For anglers and value travellers who want warm water without midwinter prices, October is a quietly strong pick, especially the back half.

💰 Average October hotel prices (Cabo San Lucas / Tourist Corridor, mid-range 4-star):
Early October: ~$190/night · Late October (Bisbee's / settling weather): ~$220/night
Rough mid-range estimates; rates vary by property and booking lead time.

So who is October for? We'd lean toward October for anglers chasing peak marlin and the tournament atmosphere, and for value travellers who want warm water with easing weather. We'd book late October for the best mix of settled conditions and warm sea. We'd only steer you to another month if you need guaranteed dry weather, in which case November onward is safer, or if whales are the goal, which means winter. Most people don't realize how quickly October improves; the difference between the first and last weeks of the month can be the difference between storm-watching and shirtsleeve evenings.

Temperature and Humidity

October is warm and gradually more comfortable as the month progresses. Daytime highs run around 30–32°C (86–90°F), with humidity easing from the September peak and evenings becoming pleasant again, with lows near 21°C (70°F). The back half of the month feels noticeably fresher than the front, signalling the return of Cabo's long good-weather season.

Rain Pattern

Rainfall tapers through October. Early in the month, brief afternoon storms are still possible as the tail of the wet season lingers; by late October, dry, settled days dominate. It is a clear improvement on September, with the trend running firmly toward sunshine.

Sea and Outdoor Conditions

The water stays warm at 28–29°C (82–84°F), excellent for swimming, snorkeling, and diving, and seas grow calmer as storm season winds down. Visibility is good, and the warm, settling conditions make October a strong all-round water month. As always, mornings are best for calm seas and clear water, and late October offers the most reliable conditions.

Cabo Weather by Month: How October Compares

October is the turn from storm season back toward the dry good-weather months. Here is how it lines up against the rest of the year across the four factors that most shape a trip.

October is a shoulder month with good value and light-to-moderate crowds, building toward the tournament buzz at the end. The month splits cleanly in two.

• Early October: cheapest, quietest, slightly riskier. The tail of the low season, with the lowest October rates and emptiest beaches, but more lingering storm odds. Good for flexible, budget-minded travellers.
• Late October: settling weather, tournament energy. Storm risk drops, weather steadies, and the Bisbee's tournaments draw anglers and a livelier marina scene. Rates rise modestly around the events. Our take: the best overall window of the month.

Expect mid-range 4-star hotels around $190/night early, rising toward $220/night late month with the tournaments and improving weather. Flights remain reasonable. Most guests find October offers a smart trade: warm water and good value with weather that gets more reliable by the week, plus a genuine big-game-fishing event if that appeals.

October's signature happening is sportfishing, and it culminates in one of the richest tournaments in the world. Dates shift year to year, so confirm specifics locally before building plans around them.

• Bisbee's Black & Blue Marlin Tournament (late October): the headline event, one of the largest big-money marlin tournaments anywhere, drawing top teams to Cabo San Lucas. Even if you're not competing, the marina is buzzing, the weigh-ins are a spectacle, and hotels fill faster, so book ahead if your dates overlap.
• Bisbee's Los Cabos Offshore (mid-to-late October): the "Little Bisbee's" precedes the main event, adding to a tournament-heavy back half of the month.
• Peak marlin season generally: beyond the tournaments, October is one of the best months of the year to fish for striped and blue marlin, dorado, and tuna out of Cabo or La Paz.
• La Paz whale shark season opening: the gentle whale shark aggregation in La Paz Bay typically begins opening up around late October, so an early-season day trip north may connect. See our La Paz whale shark guide.

The practical takeaway: if you want the tournament atmosphere or peak marlin fishing, late October is the time, and booking a charter and hotel ahead is wise around the events.

What we'd prioritise in October

October is fishing's marquee month, so we'd give the edge to a sportfishing charter at peak marlin season, with the Bisbee's atmosphere as a late-month bonus. The warm sea also makes snorkeling and diving excellent, the Los Islotes sea lion swim is open again, and the La Paz whale shark season begins opening late month. As humidity eases, desert tours like ATV rides and the zipline circuit get more comfortable.

Beyond the headliners, a few experiences round out an October trip especially well, even if they don't have a dedicated guide on this site yet:

• Marlin sportfishing charter: October's peak bite and tournament energy make a charter the standout outing of the month.
• Cabo Pulmo snorkel or dive day trip: warm, increasingly clear water makes the protected marine park's reefs a highlight.
• Bisbee's weigh-in spectating: even non-competitors can watch the late-October marina weigh-ins, a Cabo sportfishing tradition.
• La Paz whale shark day trip (late month): the gentle-giant snorkel season begins opening up; confirm it has started before booking.
• Sunset catamaran cruise around El Arco: warm, settling evenings make for excellent Land's End sunsets.

• Lean late. Late October has lower storm risk and more settled weather than early in the month, for the same warm water.
• Book around the tournaments. If your dates overlap Bisbee's in late October, reserve hotels and charters early, as the marina and lodging fill with the event crowd.
• October is peak marlin fishing. Even outside the tournaments, it is one of the best months of the year to fish; morning departures are best.
• Early October still carries storm odds. If you travel early in the month, book refundable and keep an eye on the forecast as the wet season tails off.
• The water is still warm. At 28–29°C, snorkeling, diving, and swimming are excellent and the Los Islotes sea lion swim is open again after its summer closure.
• Watch for the whale shark season. The La Paz whale shark season typically begins opening late October; confirm it has started before planning a day trip.
• Desert tours get easier. As humidity eases, ATV, camel, and zipline tours become more comfortable than in peak summer.
• Visiting at a different time of year? October eases out of storm season; our Cabo in September guide covers the stormy, cheap peak, and Cabo in November covers the dependable, dry return of high-season weather. For whales, January through March are the peak months.
