During the month of January, the weather systems that affected the country were the northeast monsoon, shear line, low pressure area, easterlies, and localized thunderstorms.
Way below to below normal rainfall conditions were experienced over most areas of the country except for near to above rainfall conditions recorded over extreme Northern Luzon, Pampanga, southern part of Quezon, northern Palawan, Romblon, Bicol Region, northern part of Panay, Northern Samar and most areas of Mindanao (Figure 1). Surigao City recorded the highest rainfall amount for the month of January (794.4 mm), followed by Tagum (681.8 mm) and Catarman Synoptic Station (572.4 mm).
Based on the Situational Report No. 1 for El Niño of the National Disaster Risk Reduction and Management Council (NDRRMC), damages to agriculture with an estimated cost of Php 108,727,672.93 with 2,580 affected farmers/fisherfolks and 2,154.43 hectares of crops.
Wet – Batanes, Quezon, Albay, Camarines Norte, Catanduanes, Sorsogon, Capiz, most of Eastern Visayas, Davao Region, Surigao del Norte, and Agusan del Norte
Moist – Lanao del Sur, Aurora, Romblon, Oriental Mindoro, Samar, Zamboanga del Norte Bukidnon, and most of BARMM
Dry – North Cotabato, Ilocos Region, CAR, NCR, Cagayan Valley, the Pampanga, Nueva Ecija, Central Visayas, SOCCSKSARGEN, and rest of the country
Generally, near average to above average surface air temperatures were observed in the country (Figure 2). San Jose, Occidental Mindoro Synoptic Station recorded the highest maximum temperature of 36.0°C (January 7) while the coldest temperature was recorded in BSU La Trinidad Synoptic Station at 9.7°C (January 28).
Zamboanga City Synoptic Station in Zamboanga obtained the highest heat index during the month of January (44°C on January 19) followed by Catarman Synoptic Station in Northern Samar (43°C on January 2) and Masbate City Synoptic Station in Masbate (43°C on January 9). The Heat Index is a human discomfort index that gives the apparent temperature on what humans perceive or feel as the temperature (from the surroundings) affecting the body. High air temperature and high relative humidity results to high apparent temperature.

The weather systems that will likely affect the country during the month of February are the northeast monsoon, shear line, easterlies, low pressure areas (LPAs), localized thunderstorms, and none or one (0 or 1) tropical cyclone (TC) may enter or develop inside the Philippine Area of Responsibility (PAR).
As shown in Figure 4, way below to below normal rainfall conditions will likely be experienced in most parts of the country. Meanwhile, near normal conditions will be expected over Caraga and most parts of the Davao Region.
Generally, near to slightly above average temperatures will be experienced in most areas of the archipelago. Meanwhile, warmer temperatures will be experienced over Dipolog and Misamis Oriental while slightly below above average temperatures will be experienced over extreme Northern Luzon, Camarines Norte, Masbate, Bohol, Southern Leyte, and SOCCKSARGEN. Cold temperature surges are also expected to occur during the Northeast monsoon season (Figure 5).
Luzon will have extreme temperature range of 9.4ºC – 27.2ºC for upland farms while 13.0ºC – 35.8ºC for other farms in Luzon; the lowland farms in Visayas will have 18.8ºC – 36.7ºC; while the upland farms in Mindanao will have 12.1ºC – 35.6ºC and 17.6ºC – 37.5ºC for lowland farms.
El Niño Southern Oscillation (ENSO) Alert and Warning System: EL NIÑO ADVISORY No. 7 (Figure 6). A strong El Niño is expected to continue through Jan-Feb 2024. Majority of global climate models suggest that El Nino will likely persist until March-April-May 20024 season with a transition to ENSO-neutral in April-May-June 2024 season.
El Niño increases the likelihood of below-normal rainfall conditions, which could bring negative impacts (such as dry spells and droughts) in some areas of the country which will likely be manifested in the first quarter of the year. Mulching must be done to prevent the rapid loss of soil moisture and to maintain the good growing condition of crops.
