There was occasional rain and quite tropical heat. Because of the rain, nature was beautifully green. Air conditioning was welcome in the afternoon.— This text is automatically translated to English

Weather experience:Excellent StarStarStarStarStar

Even though May is not known as the driest month of the year I could not complain. I was in Pattaya for the past two weeks with around 34 to 35 degrees during the day, and no less than 28 degrees on the thermometer at night. Both day and night it was oppressively hot, and cooling from both sea and pool was not really there, which were also of high temperature. I had my cooling moment at the air conditioner in my room.— This text is automatically translated to English
