During the month of October, the weather systems that affected the country were the southwest monsoon, northeast monsoon, wind flow, shear line, low pressure area (LPA), one tropical cyclone, intertropical convergence zone (ITCZ), easterlies, and localized thunderstorms.
One tropical cyclone developed and/or entered the Philippine Area of Responsibility (PAR), Typhoon (TY) “Jenny” (01 – 06 October). Based on the Situational Report of the National Disaster Risk Reduction and Management Council (NDRRMC), the combined effects of the southwest monsoon and TC occurrence does not brought damages to agriculture, livestock, poultry, and fisheries and infrastructures.
Near Normal to below normal rainfall conditions were experienced in most parts of the country as shown in Figure 1. Nueva Ecija received way below normal rainfall conditions while Ilocos Norte, Batanes, Camarines Norte, Capiz, and Davao City experienced above normal rainfall conditions. Itbayat Station in Batanes recorded the highest rainfall amount for the month of October (204.6 mm), followed by Cubi Pt., Subic Bay Synoptic Station in Olongapo (150.2 mm) and Tagum Synoptic Station in Davao del Norte (135.6 mm).
Wet – Most of Ilocos Region, most of Cagayan Valley, Cordillera Administrative Region, Aurora, Bulacan, Tarlac, National Capital Region, Most of CALABARZON, Occidental Mindoro, Romblon, Aborlan, most parts of Bicol Region, Western Visayas, Cebu, most of Eastern Visayas, Bukidnon, Davao Region, and Lanao del Sur
Dry – Tuguegarao, Ambulong, Camarines Sur, Leyte and rest of the country
Generally, near to above average surface air temperatures were felt in most parts of the country (Figure 2). Borongan Synoptic Station in Eastern Samar recorded the highest maximum temperature of 36.6°C (October 3) while the coldest temperature was recorded in BSU La Trinidad Synoptic Station at 14.7°C (October 29).
Catarman Synoptic Station in Northern Samar obtained the highest heat index during the month of October (59°C on October 4) followed by Dagupan City Synoptic Station in Pangasinan (51°C on October 31) and Borongan Synoptic Station in Eastern Samar (49°C on October 3). 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 November are the northeast monsoon, frontal system, shear line, intertropical convergence zone (ITCZ), easterlies, low pressure areas (LPAs), localized thunderstorms, ridge of high pressure area, (HPA) and one or two (1 or 2) tropical cyclones (TC) may enter or develop inside the Philippine Area of Responsibility (PAR).
Generally, way below to below normal rainfall will likely be experienced in most part of the country except in Davao City and Davao del Norte where near normal rainfall conditions are forecasted (Figure 4).
Generally, near average to warmer than average surface air temperatures will be experienced over the entire archipelago except in Benguet, San Jose, Occidental Mindoro, and Coron, Palawan where slightly cooler to cooler than average are expected. Cold temperature surges are also expected to occur during the Northeast monsoon season (Figure 5).
Luzon will have extreme temperature range of 12.0ºC – 27.2ºC for upland farms while 17.0ºC – 36.5ºC for other farms in Luzon; the lowland farms in Visayas will have 19.0ºC – 37.9ºC; while the upland farms in Mindanao will have 15.0ºC – 34.0ºC and 19.7ºC – 37.3ºC for lowland farms.
El Niño Southern Oscillation (ENSO) Alert and Warning System: EL NIÑO ADVISORY No. 5 (Figure 6). Moderate to strong El Niño is present in the tropical Pacific and showing signs of further intensification in the coming months as sea surface temperature anomalies (SSTAs) reach more than 1.5 ºC. 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. All are advised to stay updated on climate advisories, cooperate on local El Niño measures, report and fix water leaks, and always conserve water.
PAGASA will continue to closely monitor the climate conditions that may affect the country and updates shall be issued as appropriate. For further information, please contact the Climatology and Agrometeorology Division (CAD) at telephone number 8284-0800, local 4915.
