The short answer
November through April is the best time to visit Los Cabos. Daytime temperatures run 75 to 85°F, humidity is low, skies are almost always clear, and every outdoor activity from sportfishing to golf to snorkeling is at its best. If you have flexibility, November and early December offer peak-season conditions without the full peak-season crowds and pricing. Late March through April is another sweet spot: winter visitors have mostly cleared out, the weather is still excellent, and rates at many properties start to ease.
December through mid-March is the busiest stretch of the year. Resorts fill up, prices peak, and flights book out weeks in advance, especially around the holidays and spring break. If those dates are your only option, book early and expect the highest prices of the year.
May through October is the off-season. May and June are hot but dry and manageable. July through October brings serious heat, high humidity, and hurricane season. If budget is your primary consideration and you're comfortable with those conditions, summer rates can be 40 to 50 percent lower than peak season. But it's a meaningful trade-off.

What to know: season by season
November and December are the transition into peak season. Temperatures drop from the summer heat into the ideal range, 72 to 82°F during the day, 60 to 68°F at night. The Sea of Cortez is still warm from summer, hovering in the mid-70s Fahrenheit, which makes November one of the best months for snorkeling at Cabo San Lucas's coves and diving at Cabo Pulmo. Whale season kicks in mid-December when Pacific gray whales begin arriving in the waters off Baja. Sportfishing stays strong into November around the Bisbee's Black and Blue Tournament, one of the largest billfish tournaments in the world, held every October in the Cabo marina.
January, February, and March are the core of peak season. Weather is as reliable as it gets anywhere in North America: clear skies, daytime highs of 75 to 84°F, low humidity, and rarely a drop of rain. Humpback whales are active in the Pacific, and gray whale watching in the breeding lagoons of Baja Norte is at its peak January through March. This is when Los Cabos is at its most festive and its most crowded. Resorts run at or near capacity. If you're planning a honeymoon, anniversary trip, or any occasion where you want the full experience, this is the window to target. Just book well ahead of time.
April and May mark the shoulder season on the way out of peak. April still feels like peak season in terms of weather: highs in the low to mid-80s, low humidity, and clear skies. Crowds thin after spring break, and some hotels begin discounting room rates. By May, daytime temps climb toward 90°F and the water temperature rises. The whale season winds down by mid-April. May is a good value month for travelers who want solid beach weather without paying December-to-March prices.
June through October is the hot and humid season, with hurricane season running August through October. June and early July are hot but not yet humid enough to feel oppressive, with daytime highs pushing 95°F or above. August and September carry the highest hurricane risk, and while a direct hit on Cabo is not frequent, tropical storms do affect the area in some years, bringing heavy rain, rough surf, and choppy water that shuts down most water-based activities for days. The upside of summer is real: water temperatures reach the low 80s Fahrenheit, which is ideal for swimmers and snorkelers, and resort prices drop sharply. If you do visit in summer, book a resort with an indoor pool option, plan any outdoor activities for early morning, and monitor storm forecasts in the weeks before your trip.
What to know: activities and timing
Whale watching runs mid-December through mid-April. Gray whales arrive in their thousands in the Pacific waters off Baja's coast. Humpback whales are also active off Los Cabos from roughly January through March. If whale watching is a priority, a trip in January or February gives you the best odds of seeing both species on the same excursion.
Sportfishing peaks in late summer and fall. The warm water from June through November concentrates marlin, dorado, yellowfin tuna, and wahoo close to shore. September and October are often considered the best months for billfish around Los Cabos, with October being the prime marlin month. Hurricane risk is real during this window, but experienced anglers plan around it. The Bisbee's Black and Blue in mid-October draws serious fishing crews from across North America.
Golf is best November through May. The courses along the Tourist Corridor play in ideal conditions during peak season, with low humidity and cool morning temperatures. Summer golfers can still get out, but early tee times, 7 to 7:30 a.m., are essential to finish before the heat becomes a problem.
Surfing is seasonal. The East Cape and the breaks at Costa Azul near San José del Cabo see their best swells from Southern Hemisphere storms during the summer months, June through September. Winter waves are smaller. If surfing is your reason for coming, summer and early fall deliver better conditions, hurricane risk aside.
Swimming at the beach depends on which beach you choose, not just the season. Water temperatures are warmest August through October, but Médano Beach, Chileno Beach, and Santa Maria Beach are swimmable year-round. Pacific-facing beaches have dangerous currents in any month.
Practical tips
Book your flights and resort early if you're visiting between Thanksgiving and the end of March. The most popular weeks, Christmas through New Year's, spring break in March, and the week around Easter, sell out months in advance. Last-minute deals in peak season are rare at quality properties.
Consider a shoulder season trip if budget matters. Late April through May and November offer conditions that are 90 percent as good as peak season at meaningfully lower prices. The difference is noticeable: a room that runs $500 a night in February might be $300 in May.
If you're flying into Los Cabos International Airport (SJD), check the SJD airport guide before you travel. The airport serves San José del Cabo, which sits about 30 minutes from San José and 45 to 50 minutes from Cabo San Lucas. There is no reliable Uber pickup at the airport, so arrange your transfer in advance.
Plan your trip length around activities. A weekend trip can work in shoulder season when pace is slower, but if you want to hit whale watching, a round of golf, sportfishing, and one day in Cabo San Lucas, five days is the practical minimum. The 5-day Cabo itinerary is a solid framework if you're figuring out the pacing.
Hurricane season does not mean constant storms. Most summers pass without a serious storm making direct landfall at Cabo. But August and September carry real statistical risk, and travel insurance is worth purchasing for any summer trip. Check both your resort's cancellation policy and your airline's rebooking policy before you book.
Frequently asked questions
What is the cheapest month to visit Cabo?
July and August consistently have the lowest hotel rates, often 40 to 50 percent below peak-season pricing. The trade-off is heat, humidity, and hurricane risk. If budget is the priority and you can tolerate temperatures in the mid-90s to low 100s Fahrenheit, summer delivers real savings. September can be even cheaper but carries the highest storm risk of the year.
What is the weather like in Cabo in December?
December is one of the best months to visit. Early December still feels like peak shoulder season, with warm days in the mid-70s to low 80s Fahrenheit, very low humidity, and clear skies. By mid-December, whale season begins. The holiday week between Christmas and New Year's is the single busiest stretch of the year, with the highest prices and full resort occupancy. If you're going in December, book at least three months ahead for the holiday period.
Is it safe to swim in the ocean in Cabo?
It depends entirely on the beach. Médano Beach in Cabo San Lucas, Chileno Beach, Santa Maria Beach, and Palmilla Beach are reliably swimmable year-round. Many Pacific-facing beaches, including the dramatic stretch in front of the Land's End hotels, have strong currents that make swimming dangerous in any season. Always look for the beach's flag system: green means calm conditions, red means do not enter. This does not change significantly by time of year.
When is whale watching season in Cabo?
Whale watching runs roughly mid-December through mid-April. Gray whales arrive first and can be seen from December through March or April. Humpback whales are active primarily January through March in the waters off Los Cabos. The peak overlap period when both species are present is January and February, which is also the most popular time to book whale watching tours.
Is Cabo good for a summer vacation?
It can be, depending on what you're after. Summer temperatures reach 95 to 103°F with significant humidity, and August and September carry hurricane risk. That said, water temperatures are at their warmest, rates are at their lowest, and the area is less crowded than peak season. Families who like to stay close to the resort and pool find summer workable. Travelers who want to spend full days outdoors hiking, golfing, or fishing long stretches will find the heat limiting.
