Wondering where to go scuba diving in July? You’ll want to experience these liveaboard trips. Named after Julius Caesar – a popular figure from the ancient Roman Empire, July has several stand-out events that most of us remember this month. Aside from being the month where the United States celebrates its Independence Day, July is also the National Picnic Month and the World Watercolor Month. When it comes to weather and diving conditions, while it is the hurricane season in the Caribbean and scorching hot in the Red Sea, the Pacific Islands and Southeast Asian Countries have a gentle and warm climate. With this, divers across the globe prefer these countries as their dive destination. And what’s best with this good weather condition is that you can indulge in a unique kind of picnic onboard a floating hotel and go scuba diving to pristine dive sites with reefs that are brilliantly colorful.
