Barra de Navidad

We left Ajijic early on a Sunday morning. Lake Chapala had been dry and dusty, although sprinkled a couple times hinting at the rainy season to come. We were heading back to the Pacific Coast where it would be warm and humid. Descending to the coastal plain from 1,525 m (5,000 ft) on the paved road from Guadalajara to Manzanillo, we could feel the temperature and humidity increasing to 25°C (77°F) and 70% humidity. The air felt dense and heavy. What would summer be like at 35°C (95°F) and 90% humidity?

We spent five weeks on the Costa Alegre (happy or cheerful coast), roughly 300 km (180 mi) of coast south of Puerto Vallarta to Manzanillo. A tropical environment, modest beach towns and uncrowded beaches attract Mexicans on weekends and holidays from as far as Guadalajara and Mexico City (link). American and Canadian tourists and snowbirds show up in the winter (November-April) when the temperatures are warm and it rarely rains, but their presence is not large like in Puerto Vallarta.
