Monthly Philippine Agro-climatic Review and Outlook

March 2023

2

  • During the month of February, the weather systems that affected the country were the northeast (NE) monsoon, shear line, low pressure areas (LPAs), easterlies. intertropical convergence zone (ITCZ), and localized thunderstorms.
  • Generally, cloudy skies with scattered rainshowers and thunderstorms were most felt over Eastern Visayas, and Mindanao while cloudy skies with light rains were observed over Northern Luzon. Partly cloudy to cloudy skies with light rains were experienced over the rest of Luzon and remaining parts of Visayas. Flooding incidents were reported in some areas in Mindanao due to heavy rainfall.
  • Near to above normal rainfall conditions were experienced in most parts the country. Below normal rainfall conditions were experienced in most parts of MIMAROPA, provinces of Aurora, some parts of Cavite, and most parts of southern Mindanao including some parts of Zamboanga Peninsula and SOCCSKSARGEN while way below normal rainfall was observed in Ilocos Norte, Zambales, most parts of Metro Manila, Occidental Mindoro, and southern Palawan. Hinatuan Synoptic Station in Surigao del Sur recorded the highest rainfall amount for the month of February (766.7 mm), followed by Surigao Synoptic Station in Surigao del Norte (699.9 mm) and Borongan Synoptic Station, Eastern Samar (676.8 mm).
  • Derived Soil Moisture Condition (rainfed areas):
    • Wet – Calayan, Quezon, Romblon, Bicol Region, Panay Island, Bohol, Eastern Visayas, northern portion of Zamboanga Peninsula, Northern Mindanao, Tagum and Caraga
    • Moist – Aparri, Basco, Aurora, Negros Oriental, rest of the region in Zamboanga Peninsula and Davao Region
    • Dry – Rest of the country
  • Generally, near average surface air temperatures were felt in most parts of the country except for cooler than average surface temperatures that were observed in Romblon and Maasin. San Jose Synoptic Station, Occidental Mindoro recorded the highest maximum temperature of 36.0°C (February 7) while the coldest temperature was recorded in BSU Agromet Station at 8.7°C (February 12) (Figure 2).
  • La Niña Advisory #17 was issued on 06 February 2023. La Nina is weakening across the tropical Pacific Ocean. Most of the climate models suggest that La Niña will persist until January-February-March (JFM) 2023 season and then a transition to ENSO-neutral conditions is likely afterward. La Niña increases the likelihood of having above normal rainfall conditions that could lead to potential adverse impacts (such as heavy rainfall, flashfloods and landslides) over highly vulnerable areas. Adverse impacts such as floods and landslides are likely to occur over the vulnerable areas and sectors of the society.

  • Generally, near to above normal rainfall conditions are likely in most parts of the country except for the western sections of Luzon that may receive way below to below normal rainfall conditions. High probability of above normal rainfall conditions in most parts of the country (Figure 4)
  • Generally, below average to above average surface air temperatures will prevail over the whole archipelago. Increasing in the surface temperature will be felt for the month of March.
  • Luzon will have extreme temperature range of 10.8ºC – 28.1ºC for upland farms while 16.5ºC – 37.8ºC for other farms in Luzon; the lowland farms in Visayas will have 19.7ºC – 36.0ºC; while the upland farms in Mindanao will have 14.0ºC – 34.3ºC and 19.0ºC – 37.8ºC for lowland farms.
