Climate-Smart Advisories
May is the transition from dry season to the wet season of the country. This means more thunderstorms and rainshowers are expected to occur in most parts of the country for this month. Farmers are advised to watch out for the occurrence of lightning and thunderstorms. Refrain from going into farms, fields especially in the afternoon since this is the time where thunderstorms start to arise. Farmers in areas in most parts of Luzon, western Visayas and Mindanao will have near normal rainfall condition while Bicol region, central and eastern Visayas will still have below normal rainfall condition. Relating the concept of the coming of the rainy season, early folks term “Agua de Mayo”, a Spanish term means “a blessed day” or signifies that something that comes at the right moment. That is why early folks believe that Agua de Mayo – the first rains in the month of May (rainshowers with rumbles of thunderstorms) were believed to be healing, holy rains and they tend to let children play and bathe under the first rains of May.* This is a way of farmers of welcoming the start of planting season.

Agroclimatic Outlook:
  • Easterlies, Ridge of High Pressure Area, oscillation of ITCZ will be experienced during the month. Warm and humid condition will generally observe in most parts of the country.
  • Isolated occurrences of hail stones and or tornadoes in some parts of the country might be observed due to intense thunderstorms.
  • Rainfall will be getting more to near normal condition (from way below normal during the previous month) on the areas of Luzon, Western Visayas and Mindanao. Below normal rainfall condition to the rest of the country particularly Bicol Region, central and eastern Visayas.
  • Temperature range for upland farms will be 15 ºC – 26ºC and 26 ºC - 38ºC for lowland farms
  • Relative Humidity will be from 55% to 97%.
  • Weak El Nino condition is still present in the Tropical Pacific for June -August 2019.
