Climate Change Chart of Pattaya, Thailand

Overview of climate changes

Temperature changes

Averaged across calendar months, the difference in monthly mean temperature is +1.18 °C compared with the earlier reference period. This unweighted mean summarizes the month-by-month averages; it is not a day-weighted annual average or a measure of daytime maximum temperatures. The largest monthly increase was in May, at +1.91 °C. That identifies the strongest increase among the reported monthly changes, rather than describing every month.

Changes in rainfall

Averaged across calendar months, mean daily rainfall has a difference of -0.14 mm/day compared with the earlier period. This is an unweighted average of monthly mean daily amounts, not a change in annual rainfall totals, and it does not imply the same difference in every month. The largest monthly decrease was in May, with a difference of -1.44 mm/day. By contrast, the largest monthly increase was in November, at +0.82 mm/day, showing that the direction of the reported monthly differences varied.

Changes in sunshine duration

Mean daily sunshine duration had an unweighted difference across calendar-month averages of -0.45 hours/day compared with the earlier reference period. This summarizes the monthly means rather than a day-weighted annual total or conditions on every day. The largest monthly decrease was in July, at -1.06 hours/day; this marks the strongest reported monthly decline, not a uniform change throughout the year.
