September can be a tricky time to dive, as many destinations are transitioning between seasons. However, both the Sea of Cortes and Guadalupe Island in Mexico are absolutely magical to visit during September and hold the promise of unforgettable encounters with marine mega fauna. One of Australia’s best kept secrets, Rowley Shoals, has a very short season beginning at the end of September and is regarded as one of the best dive sites in Australia.

Mexico is still amazing

From August, diving in Mexico is incredible. There are two destinations to choose from, Guadeloupe Island or the Sea of Cortes, and your choice will be dictated by what marine life you most want to dive with.

Guadeloupe Island, off the Baja Peninsula is a hot spot for Great White Sharks. In Guadeloupe, you can come fact to face with these enormous ocean predators. Guadeloupe is arguably the best destination for diving with these sharks, as the visibility of the crystal clear water often exceeds 35 metres and it’s not uncommon to have 6 sharks surrounding the cage on a single dive. September is the month when big females start showing up in Guadeloupe, and these sharks can grow more than 5 metres in length.

The Sea of Cortes, also in Mexico, is often compared to an aquarium thanks to its incredible visibility and stunning array of marine life. The beauty of the Sea of Cortes lies in the huge amount of marine biodiversity that can be seen there. From diving with curious Californian sea lions that love nothing more than coming up and sniffing a camera dome, to the macro life scattered along the coral reefs, there is life everywhere you look. The area is renowned for being one where you’re guaranteed to dive with sea lions, and you’ll encounter mantas, sharks and even dolphins, along with huge schools or pelagic fish.

Australia’s hidden gem

Australia is most well known for it’s iconic Great Barrier Reef, but on the other side of the country lies Australia’s best kept secret. Rowley Shoals Marine Park is 300 kilometers off Broome, Western Australia. Blink and you’ll miss this spectacular locations dive season. .

Visit the ‘friendliest people on Earth’

Fiji is a tropical paradise with fantastic diving, and the hospitality to travellers has resulted the country being coined as one of the friendliest in the world. During the month of September the humidity and heat in Fiji is not overwhelming, and the water is cooler which results in phenomenal visibility. September is the tail end of winter in Fiji, and with water temperatures rarely dropping below 24 degrees Fiji is by no-means cold. You can expect visibility of around 30 metres dive after dive during winter, and the cooler air temperatures mean you won’t be sweating in the hot tropical sun during your surface intervals.

The favourable conditions of Fiji make this a destination that can be dived by those with only their Open Water Certification. Most liveaboards, such as the Fiji Siren and Fiji Aggressor, will ask that divers who book a liveaboard have a minimum of 20 or so dives logged for safety precautions. You can expect a mixture of dive types onboard a liveaboard in Fiji. Drift dives are the norm in Taveuni Island, and a site called ‘Rainbow Reef’ will have you dazzled by the stunning array of colours on both the coral reefs and fish that call it home.
