Monthly Philippine Agro-climatic Review and Outlook

July 2022

7

  • During the month of July, the weather systems that affected the country were the southwest monsoon, intertropical convergence zone (ITCZ), low pressure areas (LPAs), two tropical cyclones, localized thunderstorms, easterlies, and ridge of high pressure area (HPA).
  • Two tropical cyclones developed inside the Philippine Area of Responsibility (PAR), east of extreme northern Luzon. Tropical cyclone “Domeng” intensifies into a Tropical Storm (TS) on the 1st day of July and it accelerated moving outside the PAR on following day. This weather system does not directly affected the country, however, the southwest monsoon enhanced by this tropical cyclone, brought cloudiness and scattered rains over the western section of Central and southern Luzon. Tropical Depression “Ester” (29 -31 July) developed and exited PAR. The western side of Central and Southern Luzon experienced cloudy skies and monsoon rains brought by the enhanced southwest monsoon.
  • Monthly total rainfall recorded way below to below normal rainfall conditions over the wester section of Luzon and below to near normal rainfall conditions over Southern Luzon and Visayas. Generally, the rest of the country received near to above rainfall conditions. (Figure 1).
  • Derived Soil Moisture Condition (rainfed areas):
    • Wet – Ilocos Sur, Pangasinan, Isabela, Nueva Viscaya, Cordillera Administrative Region, Quezon City, Cavite, Batangas, Rizal, Quezon, Mindoro, Northern Palawan, Camarines Sur, Albay, Catanduanes, Sorsogon, Negros Occidental, Zamboanga Peninsula, Bukidnon, Bangsamoro Autonomous Region of Muslim Mindanao, Central Luzon, CALABARZON, most areas in Western Visayas, Eastern Visayas, Davao Region and Caraga
    • Moist – Batanes, Romblon, Pag-asa Island, Camarines Norte, Negros Oriental, Bohol, Davao City, Surigao del Norte, most areas in Ilocos Norte and Sorsogon, and rest of Cagayan Valley, National Capital Region, Albay and Western Visayas
    • Dry – rest of the country
  • Generally, near to slightly warmer than average surface temperatures were experienced in most parts of the country except in Occidental Mindoro, Camarines Norte, and Tayabas, Quezon that recorded slightly cooler to cooler than average surface temperature (Figure 2). NAIA, Pasay recorded the highest maximum temperature of 35.9°C (July 11) while the coldest temperature was recorded in BSU Agromet Station in Benguet at 15.0°C (July 5).
  • La Niña Advisory #10 was issued on 05 July 2022. La Niña is weakening in the tropical Pacific and may still persist until the end of the year with a 52 – 59 % chance. La Niña increases the likelihood of having above normal rainfall conditions in some areas of the country. Adverse impacts such as floods and landslides are likely to occur over the vulnerable areas and sectors of the society.
