Explore Puerto Vallarta
Puerto Vallarta is a beach resort/cruise ship port city in the Mexican state of Jalisco. Puerto Vallarta is located on a large bay facing the Pacific Ocean called Bahía de Banderas (Banderas Bay). In addition to its beautiful beaches and rapid development, Bahía de Banderas is known for being a breeding ground for humpback whales.
Scuba diving is one of Puerto Vallarta’s main attractions. Diving in Bahía de Banderas is great for novice divers because the currents are mild. Various local dive shops offer certification courses and they take their students to dive here as well. These dive shops also organize daily boat trips out to the offshore islands of Los Arcos and Las Marietas Islands for some more advanced diving. The biodiversity of marine flora and fauna at these islands is spectacular, which makes sense because Los Arcos, or Los Arcos de Mismaloya, is a National Marine Park and Las Marietas is a protected wildlife sanctuary.
The best Months to dive in Puerto Vallarta
The best time of year to dive the offshore sites such as Los Arcos and Las Marietas is from November through May, when the ocean conditions are calmest. This is also the time of year when divers have the chance of spotting manta rays and whale sharks, as well as humpback whales. Visibility can be slightly worse during these times, however, due to the plankton blooms that are attracted by the cooler waters.
If you prefer warmer waters (26°C/78.8°F) and the best visibility, June through October is the ideal time to go.
