Where should you go in Thailand in july when it comes to the weather?

Remember:
The climate in Thailand in july ranges from good to very bad depending on the region and city.

The climate in Thailand in July saw the rains increase unevenly across the country, but temperatures remain relatively high. Consequence: the degree of humidity makes the atmosphere oppressive in continental regions. This is the beginning of the proper wet season, therefore an umbrella is needed!

Bangkok and Central Thailand in July

The monsoon wets this part of the country between fifteen and twenty days within the month. The thermometer displays an average of 30° C and the sunshine in Bangkok is still reduced by one hour compared to June. The continental provinces require caution in some places in view of the sudden floods. Do not forget to consult the weather report before going on an excursion!

East of Thailand (Isan) in July

The monsoon now falls on the extreme east of the country. Roads and hinterland sometimes become impassable. Koh Chang does not escape this rainy weather, with a sea often agitated and hazardous sea links. For a drier stay by the sea, it is better to opt for Pattaya. The thermometer presents an average of 23-24 ° C overnight and 30° C during the day.

Northern Thailand in July

The rainy season is in full swing in northern Thailand. If national parks and waterfalls become magnificent, beware of slippery terrain and sudden floods. There are about 20 rainy days, with a hot and humid atmosphere that is difficult to bear. When it comes to temperature level, the month shows an average of 29° C with peaks at 33° C.

Northeast Thailand in July

There is a slight decrease in temperature in the Northeast compared to June. The thermometer travels between 24° C at night and 31° C during the day. Expect about twenty rainy days and therefore a damp, hot and uncomfortable air. The extreme northeast is subject to heavy showers, therefore caution for novice hikers!

Southeast Thailand in July

July on the southeast coast of Thailand does not differ from June except for a few more showers. The Gulf water displays 28° C and for average night air temperatures, about 25° C all the way to 32° C during the day. The islands of Koh Samui, Koh Phangan and Koh Tao remain welcoming, but for a drier stay, opt for coastal destinations in the northwest of the Gulf of Thailand.

Southwest in July

The rains are intensifying and the Andaman Sea can become difficult to navigate under the effect of the winds, prohibiting any transport between continent and islands. The seaside resorts that are still open offer very attractive prices, but the sun can be made rare throughout some weeks of August. However, the temperature remains high with a varying thermometer of 26° C at night at 31° C during the day. If Koh Lanta turns out to be drier than Phuket, it is still better to choose a destination in the Gulf of Thailand - except Koh Chang, which is too rainy.
