Pattaya has one of the steadier climates in our dataset. Average highs move only 3°C across the whole year - from 87°F (30°C) in January to 91°F (33°C) in April - so the practical difference between seasons here is rainfall and daylight, not warmth.

Choosing the right part of the year in Pattaya
Choose dates by rain, not just temperature
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.
What the humidity changes
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.
