Climate-Smart Advisories
The month of August is usually the peak of the wet season which the Southwest monsoon or locally known as “habagat” prevails and brings rains over the western section of Luzon and Visayas. Generally near normal with patches of above rainfall conditions are expected in some areas of CALABARZON, Mimaropa, NCR, Bicol Region and Isabela. Likewise, isolated thunderstorms and rainshowers are still expected to occur in most parts of the country. Farmers are advised to regularly consult the expertise of agricultural workers of insect pest occurrence for each crop during rainy season.
  • Southwest monsoon will be experienced particularly in western section of Luzon including western Visayas Isolated rains and thunderstorms are still expected to experience in most parts of the country.
  • Rainfall will be near normal to above normal conditions over some areas of Luzon and Visayass, while generally below normal over southern portion of Mindanao.
  • Two or four tropical cyclones are expected to enter the PAR.
  • Temperature range for upland farms will be 15ºC – 25ºC and 24ºC - 38ºC for lowland farms.
  • Relative Humidity will be from 55% to 100%.
ENSO-neutral is favored to emerge in September 2019 until the first quarter of 2020
