Best time to visit Pattaya
November to April is the sweet spot for Pattaya - humidity and rainfall are at their lowest, which is what actually varies here. Expect 88°F (31°C) in the afternoon and around 10 days of rain in a typical month of it. For the same question asked the other way round, see where else is warm in November.
Pack for Pattaya with lightweight, breathable clothing and serious sun protection, proper waterproofs rather than an umbrella - wet days are the norm here and moisture-wicking fabrics for the humidity. April nights average 80°F (27°C), so evenings rarely match the afternoons.
