September 15 is Costa Rica's Independence Day — observed with a particular pride that feels genuine rather than performed. The evening before brings the desfile de faroles, where schoolchildren carry handmade paper lanterns through darkened streets. The dawn hours of September 15 itself have a quality that photographers refer to simply as the September light — an atmospheric combination of late green season humidity and clear early mornings.

Photography
The Independence Day lantern parade (the evening of September 14) is one of the most photogenic events in the Costa Rican calendar. Low light, moving subjects, handmade lanterns — it rewards fast lenses and patience.
Worth knowing
September is one of the wettest months on the Pacific slope. Some lower-elevation roads flood periodically — always check road conditions before driving remote routes.
Event note — Independence Day on September 15. The night before (September 14) brings the desfile de faroles — lantern parades in every town. San José's central park and Cartago are the largest gatherings.
