Hopper Editors - Oct. 26, 2017

The beaches, temperate climate and all-round feel-good vibe in San Diego earned the city its nickname as America's Finest City. Mexico's beach-lined party city isn't a world apart from California's bronzed and beautiful second city, but those seven hours in the air will transport San Diegans to a more party-centric ambience and some more Mexican cuisine. San Diegans are so busy "staying classy" (thanks, Ron Burgundy) that it's no wonder they might want to let go a little in the city where they can let their hair down and party as hard as the next spring breaker. Whatever it is motivating San Diego locals to flee the American beaches for the Mexican shoreline, cheap flights from San Diego to Cancun are just a few clicks away. Follow these tips to get the very best deals on the San Diego to Cancun route.

1. The cheapest time to book a flight from San Diego to Cancun is 20 days in advance, saving up to $80

The rates on the San Diego to Cancun route won't penalize late bookers much. Prices are steady in the months and even weeks approaching your departure, although there is a marked – if relatively small – increase around three weeks before your departure date. The hike equates to less than a hundred dollar difference between your departure date and 20 days before departure. So, if you're a San Diegan couple hoping to impulsively elope or an unprepared Best Man putting together a hastily organized Bachelor party, Cancun is a very feasible option – even at the last minute.

2. The cheapest time to fly from San Diego to Cancun is after May, saving up to $150

Although advance booking has a minimal impact on San Diego - Cancun rates, the prices of flights on this route vary wildly from month to month. April and May are two of the most popular choices for San Diegans traveling to Cancun, and May is accordingly the most expensive time to fly. Between January and May, flights are at the higher end of the scale – hovering at $600 and above. Prices take a nosedive when the spring break crowd clears out in June. Summer is a great time to travel to Cancun from San Diego, as prices are bottoming out at some of their lowest in these months. November's prices are the lowest in the year, at a full $150 cheaper than those of May, on average.

3. The cheapest day to fly from San Diego to Cancun is on a Tuesday, saving up to $45

Tuesday is the best day to hop on that flight from San Diego to Cancun, giving eager voyagers the benefit of a full week of sun on less crowded beaches, and time to develop that beachy sun-kissed glow before the weekend rolls around and it's time to party extra hard. Cancun has lots going on both during and outside of the peak weekend days and nights – why not use that extra $45 you saved on a boat trip or dolphin dive?

4. Save up to $33 by returning on a Thursday

Return on a Thursday and save up to $33 on your return flight. You'll avoid peak rates on hotels over the pricey weekend days, and you could also have a weekend to unwind before returning to the office basking in post-vacation glory. Weekends are known to get pretty wild in Cancun, so flying back to San Diego on a Thursday means cleverly avoiding the potential Monday morning fall-out from the Saturday and Sunday night revelry.

5. The cheapest day to buy a flight from San Diego to Cancun is on a Thursday, saving up to $34
