This is the maximum amount of sunshine in the year, a number that is shared with February and March.

    Cloud Cover

The two most common types of precipitation are light rain and thunderstorms, respectively occurring on 42% and 41% of the rainy days. The chance of thunderstorms increases greatly in the course of the month though. Luckily these storms are generally short-natured.

    Ko Samui Beach for April

Maenam is the place to be if you want get away from it all on a budget. Some people stay for weeks, others for months on end, in the cheap bungalows that dot the beach.

    Things to do in Ko Samui in April

    The Horse Riding Samui School

    A great way to see and explore the island of Ko Samui is on horseback. Sure, driving around and going on boat trips is a lot of fun, but horseback riding is a great way to wind down and slow down. This allows you to enjoy the views even better! The Horse Riding Samui School offers horseback rides on the beach or through the jungle. You will receive instructions and a lesson before setting off to explore Lipa Noi Beach, the dense jungle or the mountains and Laem Sor Pagoda. There are 1-hour, 2-hour, 4-hour programs, as well as a three-day course that includes lessons on how to clean nails, shower a horse, set up equipment, etcetera.

    Samui Bungy Jump

    Thrill-seekers may want to skip horseback riding and go for more exciting activities. Bungee jumping is definitely one of those. Samui Bungy Jump is located in Chaweng and certainly provides the thrills you may be looking for. They will shoot you up into the air, which is followed by a free-fall and several bounces over the deepest swimming pool in southern Thailand. In addition to regular jumps, they also offer specialist jumps, such as backward, reverse and running jumps.

    Hin Ta and Hin Yai

    Another completely different experience can be had on the south coast of the island. There you can visit Hin Ta and Hin Yai, also known as the Grandfather and Grandmother Rock. These famous rocks are possibly the most-photographed natural feature in the resort. It is easy to see why they're so popular; they are shaped like male and female genitalia. Of course, such-shaped rocks have a legend attached to them. The local folklore goes that an old couple's boat sank in a storm, after which they were washed ashore and turned into stone.

    Lamai Beach

    The rocks are located next to a small sandy beach that, unfortunately, is not suitable for swimming. However, the water is so clear that fish and other marine life can be seen from the surface. From the rocks, you can enjoy great views across the sea of nearby islands. Hin Ta and Hin Yai are situated south of Lamai Beach. Around the site you will find lots of food and souvenir stalls, souvenirs including Grandfather Rocks in all sizes. A suggested place to visit nearby is the Muslim village of Huan Thanon, which is surrounded by plantations and buffalo fields. This may be as close as you can get to a view of traditional life on Ko Samui before the tourists arrived.
