September features both cultural celebrations and quieter tourism activity. In Los Cabos, Mexican Independence Day (September 16) brings vibrant local fiestas, parades and special dinners in San José del Cabo and Cabo San Lucas—book restaurants and transfers early. The shoulder season means fewer large-scale festivals but more authentic local events. In Seattle, late-summer outdoor concerts and Mariners baseball games near the city may affect hotel and transport availability slightly. Use event-based search terms like 'Los Cabos September events' or 'SJD Independence Day celebrations' when planning.
The best overall time to fly Seattle (All Airports) (SEAA) to Los Cabos International Airport (SJD) is November through April, when weather is dry and flights are frequent. September offers the cheapest fares and lower crowds due to hurricane season; however, increased risk of storms and occasional schedule disruptions make it better suited for flexible travelers. If you prioritize weather and activities, choose winter months; if you prioritize price, consider September but secure flexible tickets and travel insurance.
Choosing nonstop flights from Seattle (All Airports) (SEAA) to Los Cabos International Airport (SJD) saves time (about 4.5–5 hours) and reduces connection risk—valuable during September when weather can delay flights.
