Finding the cheapest time to fly to Los Cabos comes down to understanding the destination's seasonality. Cabo is a year-round destination — it gets 350 sunny days a year, the resort scene never shuts down, and the airport (SJD) has consistent nonstop service from major West Coast hubs. But airfare varies dramatically month to month, and the difference between flying in shoulder season versus peak season can be hundreds of dollars per person. In this month-by-month guide to Cabo flight prices, we break down when fares are lowest, when they spike, the cheapest specific weeks to target, and the booking strategies that actually move the needle. If you are flexible on dates, this guide will help you save serious money on your Los Cabos trip.
1The cheapest months to fly to Cabo
September and October are typically the cheapest months to fly to Los Cabos, with round-trip fares from major West Coast cities often dropping to $250 to $350 in economy. The catch: this is the tail of hurricane season (peak in September and early October), and the weather is hot and humid. May and early June are the sweet spot — fares drop after Easter but the weather is still gorgeous, with warm water and low humidity. Late August is also cheap for the same reasons as September. The trade-off is always weather — the cheapest months are cheap for a reason. If you can be flexible with dates and are willing to risk the slim chance of a September storm, the savings are real. Travel insurance is genuinely worth it for September and October trips.
2The most expensive weeks to avoid
Christmas week (December 20 through January 3) is the most expensive time to fly to Cabo, with round-trip fares often doubling or tripling shoulder-season rates. Presidents' Day week in mid-February is the second-most-expensive, coinciding with peak whale watching season and spring break for some colleges. Easter week (Semana Santa) is a major Mexican holiday and fares spike as domestic travelers fill resorts. Spring break weeks in March and early April are also expensive. Thanksgiving week is expensive but slightly less so than Christmas. If you can avoid these five windows — Christmas, Presidents' Day, Easter, Spring Break, and Thanksgiving — you will save dramatically. If you must travel during these weeks, book three to six months in advance; last-minute fares are brutal.
3Month-by-month breakdown
January: peak whale watching, high fares (especially MLK weekend). February: peak season, highest fares around Presidents' Day. March: spring break, high fares. April: Easter spike, then fares drop in late April. May: shoulder season, great fares, excellent weather — one of the best value months. June: summer starts, fares moderate. July: hot, moderate fares. August: hot, low fares in late August. September: cheapest month, hurricane season peak. October: cheap early, fares rise late as weather improves. November: fares rise through Thanksgiving. December: cheap early, peak fares the last two weeks. The pattern is clear — May, September, and October are the cheap windows, with May offering the best weather-to-price ratio.
4Best booking strategies for Cabo flights
Book one to three months in advance for shoulder season (May, October, November); three to six months in advance for peak season (Christmas, Presidents' Day, Easter). Track fares with Google Flights price alerts for your specific dates — Cabo routes from major West Coast hubs (LAX, SFO, SAN, SEA, PHX) have enough competition that deals appear regularly. Southwest, Alaska, and Delta are the dominant carriers from the West Coast; United and American fly nonstop from hubs like Denver, Houston, and Dallas. Tuesday and Wednesday departures are typically cheaper than weekend departures. Saturday night stays often unlock lower fares on legacy carriers. Consider flying into La Paz (LAP), three hours north, for very cheap fares from some Mexican cities — but the ground transfer eats the savings for most travelers.
5Cheapest cities to fly from
Los Angeles, San Diego, San Francisco, Phoenix, and Denver have the cheapest nonstop fares to Cabo year-round because of the volume of competition. Los Angeles to Cabo can be found for under $300 round-trip in shoulder season. San Diego is sometimes even cheaper given its proximity. From the East Coast and Midwest, expect to connect through Phoenix, Denver, Dallas, or Houston, which adds $100 to $200 and 2 to 4 hours each way. New York, Atlanta, and Chicago have seasonal or limited nonstop service to Cabo; check routes carefully. From Canada, Vancouver and Calgary have nonstop service seasonally. If you live in a city without nonstop Cabo service, the cheapest option is often to fly to LAX or PHX and connect from there — the LAX-Cabo leg alone is routinely under $250 round-trip.
6Flight plus resort packages
Bundling your flight and resort through a travel advisor can save 10 to 25 percent versus booking each separately, especially for all-inclusive resorts and peak-season travel. The Vacation Planning Company network has access to wholesale airfare and contracted resort rates that are not available to direct bookers. Packages are particularly valuable during peak weeks (Christmas, Presidents' Day, Easter) when last-minute direct booking fares are brutal. For shoulder-season trips where airfare is already low, the package savings are smaller but still worth comparing. Always get a package quote before booking direct — there is no cost to compare, and the savings can be hundreds of dollars per couple.
