Weather in Thailand in April

The hottest conditions in April tend to be felt in the inland and central areas, where the heat builds through the day with little relief.

• Bangkok: Warmest Regions in April: Sitting on the south-western coast of Corfu, Paleokastritsa draws visitors with its sheltered coves, turquoise water and gentle spring sunshine. April temperatures here typically reach the low twenties, making it an ideal base for swimming, boat trips and coastal walks before the summer crowds arrive. It is exactly the brief our Thailand holidays deals are built around.
• Ayutthaya: Ayutthaya, the former capital sitting on the central plains, feels the heat intensely in April. Its UNESCO-listed ruins are largely open-air, offering little shade between temples, so a bicycle ride at dawn or late afternoon is the sensible approach. Many visitors combine a day trip from the capital with a short rest back in cooler air. The ruins repay the effort, but they are best enjoyed outside the hottest hours.
• Kanchanaburi: Kanchanaburi lies west of the capital, where April temperatures run high and the landscape can feel dry and exposed. The region is a useful day trip for Erawan National Park, where the cascading pools offer a welcome chance to cool off in the water. Arriving early in the morning helps avoid both the crowds and the strongest sun. We regard it as a good add-on for travellers who want nature alongside the capital's heat.
• Sukhothai: Sukhothai, in the north-central plains, is typically very warm in April, and its historical park is largely unshaded. The ruins of the first Siamese capital are less visited than those further south, which means fewer people compete for space in the heat. Cycling between the temples is the most common way to explore, and an early start makes the experience far more comfortable. It is a quieter choice for those prepared to accept the warmth in exchange for space.
• Khao Sok: Khao Sok National Park sits in the rainforest of the south, where humidity is usually high in April even though rainfall is often lower than in the wet months. The dense canopy provides more shade than the open plains, making jungle walks more manageable during the day. Floating accommodation on the reservoir offers a memorable way to escape the land heat. It suits nature lovers who value shade and water more than sunshine.
