During the second half of the dekad, the whole country will have good weather associated with partly cloudy to cloudy skies with isolated rainshowers. However, Northern Luzon will experience cloudiness with scattered rainshowers and thunderstorms during the latter part of the forecast period. The rest of the archipelago will have partly cloudy to cloudy skies with chances of isolated rainshowers.
During the early days of the forecast period, winds from the northeast will prevail over the extreme Northern Luzon while the rest of Northern Luzon will have winds from the northeast to northwest. The rest of the country will experience winds coming from the southwest to west. Winds from the south will gradually prevail over Mindanao during the mid of the dekad while the remaining portions of the archipelago will have winds from the south to southeast. During the latter days of the ten-day forecast, Southern Luzon, Visayas and Mindanao will have winds blowing from the east to southeast while Northern Luzon will have winds from the northeast to northwest. The rest of Luzon will experience winds coming from the east to south.
The coastal waters over extreme Northern Luzon will be moderate to occasionally rough while the rest of the archipelago will have slight to moderate seas during the start of the dekad. After this, the whole country is expected to have slight to moderate seas. During the latter days of the forecast period, Northern Luzon will gradually experience moderate to occasionally rough seas while the rest of the archipelago will have slight to moderate seas.
Weak El Niño is present in the tropical Pacific.
FARM ADVISORIES:
It is recommended that one step to successful rice production is the use of a crop calendar. A crop calendar is a picture of your rice growing season (crop production from the fallow, land preparation, crop establishment, and maintenance through harvest and storage). By using a crop calendar, farm activities are better planned and performed at the right time. It is easier to organize labor and obtain inputs such as seed and fertilizer. Better planning will decrease input costs and increase yields.
How to create a crop calendar:
· Determine the best date to plant. Determine the time the variety takes from planting to harvest (short duration, 100–120 days; medium duration, 120–140 days; long duration, 160 days or more). Most varieties take 50–55 days from panicle initiation to harvest. Mark on the calendar the date of planting and when each other operation needs to be done (plowing, weeding, fertilizing, and harvesting). Pin the calendar in a prominent place to remind you when things need to be done. *
