Big Blue Diving Koh Tao

🌦️ **Why Can't We Always Dive Sail Rock In June?**

June is part of the Gulf of Thailand's south-westerly monsoon season. While we still get plenty of sunshine, stronger winds and occasional afternoon storms can create rough seas offshore, making sites like Sail Rock, Chumphon Pinnacle and Southwest Pinnacle inaccessible at times.

The good news? Diving doesn't stop. Koh Tao's sheltered east coast often provides excellent conditions, and sites like Laem Thien, Hin Wong Pinnacle and the HTMS Hanhak Sattru Wreck can be absolutely fantastic this time of year.

We always choose the best dive sites based on the day's conditions, ensuring safe diving and the best possible underwater experience. 🌊🐠🤿

Sometimes the best dives aren't the ones you planned—they're the ones the weather gives you!

🌊 MEET OUR IN-HOUSE MARINE BIOLOGIST 🌊

Say hello to **Isabel**, our Manager at Big Blue Conservation ! 🐠🐢🪸

With an MSc in Tropical Marine Biology and a passion for ocean conservation, Isabel brings a wealth of experience to Big Blue. Her work has taken her from sea turtle conservation projects in Costa Rica and cetacean monitoring in Wales to coral reef surveys right here in Thailand.

Since joining Big Blue Conservation, Isabel has been involved in coral restoration, marine research dives, and education programs designed to inspire the next generation of ocean advocates.

Her particular interests include coral health, reef resilience, and understanding how climate change is affecting our underwater ecosystems. But what she enjoys most is sharing her knowledge and helping people see the ocean through a scientist's eyes.

Whether she's underwater collecting data, restoring coral reefs, or talking marine life with divers, Isabel is helping us better understand and protect the incredible marine environment around Koh Tao.
