Wondering about the weather in Thailand in July? Read on to find out all you need to know about the weather in Thailand in July. Here, we'll cover everything from average air and sea temperatures to what to look forward to on your Thailand vacation and what to expect from the crowds.

Visiting Thailand in July has its pros and cons. Although it’s the rainy season, with hot and humid weather and frequent downpours, this time of year has its advantages. The lush green landscapes are stunning, and fewer tourists mean better deals on accommodation and flights. If you're planning a trip to Thailand, July can be a great time to experience the country without the peak-season crowds — just be ready for unpredictable weather.
However, rainfall can hamper outdoor activities, and some beaches and islands may be temporarily closed due to rough seas. If you're traveling to Thailand with kids, consider visiting indoor attractions like Bangkok’s SEA LIFE aquarium or Chiang Mai’s interactive museums to keep little ones entertained during rainy days. To make the most of your trip, embrace the local festivals, explore cultural sites, and enjoy a quieter, more authentic side of Thailand.

July continues Thailand’s wet season, but it’s not all doom and gloom. Bangkok sees temperatures between 79°F (26°C) and 91°F (33°C), with around 6 inches (150mm) of rain. Chiang Mai cools slightly with highs around 89°F (32°C) and lows of 74°F (23°C).
The southern coasts, including Phuket, Krabi, and Samui, experience heavier rainfall—up to 12 inches (300mm) — with temperatures ranging from 78°F (26°C) to 88°F (31°C). Even with the rain, you’ll still get about 5-6 hours of sunshine per day.
Northern Thailand’s landscapes are at their greenest during this time, making July a good choice for nature lovers. Showers are usually heaviest in the afternoons and evenings, leaving mornings relatively dry for exploring. Depending on your travel style, this can still be one of the best times to visit Thailand if you’re looking for lush scenery and fewer crowds.

Tourism picks up again as European and North American families take summer vacations. Prices rise slightly, especially in popular beach destinations like Phuket and Koh Samui, but they’re still lower than peak season. If you're looking for the best places to visit in Thailand during this time, the Gulf Coast islands — Koh Samui and Koh Phangan — are great options, as they experience less rain compared to the Andaman Coast. The rain is still present but usually comes in short bursts, allowing for plenty of beach time and outdoor activities between showers.
