Not really. Checking the Thai Meteorological web site for my town (Nakhon Sawan) I see a current humidity of 59%. Seems to me when I was living in Washington, D.C., the humidity in the summer was often higher than that.
We're near the end of the rainy season right now, but in November we start the cold dry season, when it might not rain once a month but the weather can get quite cold at night; daytimes it will still get up to the low 80s. Then we have the hot dry season from February through May. This year we've had a lot less rainfall than normal, and the farmers are going to suffer from a lack of irrigation water.
My biggest problem is the sunlight is so strong, especially just after noon. The sun is closer to the zenith throughout the year, so it passes through less atmosphere to the ground. During the rainy season there is usually some high haze, too thin to call clouds, that does reduce the sunlight some. I've got a couple of Vandas that get quite a lot of direct sunshine. I wish I had a place I could keep them that was more moderate, but it seems like a choice between no sunlight or too much. I learned the hard way to keep my dendrobiums out of the sun, but I'm still feeling my way with the Vandas.
