Coconut Growing Zones and Production Suitability of the Crop
Based on the figure above, a total of 29 provinces are situated in the wet growing zone (WGZ) that is highly suitable for rainfed coconut production year-round, with average annual yields of at least 2.5 tons copra or 11,250 nuts per ha.
42% of the total provinces fall under the WGZ, most of these provinces are located in the eastern parts of Mindanao and the Visayas which has the main advantage of having a highly adequate and well-distributed supply of rainfall year-round required for a sustained supply of nuts for various coconut processing and marketing sectors. Most of the large oil mills/refineries and other product processing plants are located close or within to the WGZ for their economic and orperational advantage.

WET GROWING ZONE (WGZ) has highly adequate supply of rainfall year-round, with not more than 3 dry months, annually.
INTERMEDIATE GROWING ZONE (IGZ) has adequate rainfall year-round, only 3-4.5 dry months.
DRY GROWING ZONE (DGZ) has rainfall not well distributed, not less than 6 dry months
