Monthly Weather Summary
The rather active high pressure area from China periodically extended to cover upper Thailand especially during the second half of the month. At that time, cool weather occurred across the northern and northeastern parts with cold weather in some areas including the mountainous areas and mountain top. Mean monthly temperatures were 1-2 ºC higher than normal especially in upper Thailand. The tropical depression in the Bay of Bengal and the low pressure cell covering the coastal areas of Myanmar brought unusual rainfall to upper Thailand during early month. Moreover, the prevailing of the easterly wind and the remnant of the tropical storm SINLAKU (1421) over Cambodia resulted in more rainfall during late month. Besides, southern Thailand received plentiful of rain especially along the east coast with flash flooding in some places during mid-month caused by the northeast monsoon and the low pressure cell covering over the Gulf of Thailand and southern Thailand during early and mid-month. Monthly rainfall was above normal in most parts of Thailand i.e. northern part 15.4 mm (47%), central 17.6 mm (47%), eastern 36.3 mm (68%) and southern part (west coast) 60.6 mm (31%) except for that in northeastern and southern parts (east coast) were below normal 0.7 mm (4%) and 48.2 mm (13%), respectively.
