MANILA, Philippines — The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) said the country will experience its longest day of the year on June 21.
The phenomenon, known as ‘summer solstice’, is the time when “the sun attains its greatest declination of +23.5 degrees and passes directly overhead at noon for all observers at latitude 23.5 degrees North, which is known as the Tropic of Cancer,” PAGASA said.
This means daytime on June 21 will last for 12 hours and 59 minutes as the sun will rise at 5:28 a.m. and will set at 6:27 p.m.
It also means that daytime will be longer than nighttime in the next three months.
‘Summer solstice’ signals the beginning of the summer season in the Northern Hemisphere.
It is the opposite of ‘winter solstice’ or the time when the shortest day and longest night occur usually every 21st or 22nd of December each year.

MANILA, Philippines – Water level in Angat Dam is nearing critical level, according to the National Water Resources Board (NWRB), despite state weather bureau PAGASA’s announcement of the onset of the rainy season last Friday (June 14).
Thus, customers of Manila Water and Maynilad are advised to store water in the days to come in preparation for possible water problems.
“We wanted to clarify na sa ngayon hindi pa ganuoon ka-komportable ang sitwasyon kung ang pinaguusapan natin ay ang suplay ng tubig sa metro manila,” explained NWRB Director Sevillo David Jr. said.
(We wanted to clarify that we cannot be that comfortable with the current situation in terms of water supply in Metro Manila.)
“Kasi po sa ngayon is way below normal po and natatanggap nating tubig sa Angat Dam,” he added.
(It is because the (water supply) we receive for Angat Dam is still way below normal.)
As of 6:00 a.m. Monday (June 17), Angat Dam’s water level is at 162.39 meters, only about two meters high that its critical level of 160 meters.
According to the NWRB, Angat Dam can still supply the water requirements to Metro Manila, Cavite, Rizal, and Bulacan even with only 160 meters to 155 meters water reserve.
However, the public will have to work on a very limited supply of water if that happens.
The NWRB said Angat Dam’s reserve may dip up to 155 meters if rains will be scarce until the third week of July.
PAGASA said the El Nino phenomenon may persist up to October this year and the only way to increase water level in Angat Dam is through the entry of tropical cyclones.
“Actually, itong mga dams naman natin talagang mapupuno ito. Two to three bagyo lang puno na iyan (Actually, two to three cyclones are enough to fill our dams),” said DR. Esperanza Cayanan, Chief of PAGASA Weather Forecasting Division.
Maynilad and Manila Water started implementing low pressure to no water during peak hours to their customers since last week.
But if Angat Dam’s water level reaches the critical level, the water concessionaires will opt to implement water service interruptions during peak hours.
The water distributor assured, however, that they will give their customers enough time to store water for their domestic needs prior to service interruptions.
“When that happens na mareach natin ang 160 meters sa Angat Dam then we would have to implement officially this time yung rotational service interruptions na and it will be implemented mararamdaman during peak hours,” said Jennifer Rufo of Maynilad.
(When that happens that Angat Dam reaches 160 meters, we would have to implement officially the rotational service interruption during peak hours.)
“Ang standing order namin is as much as possible gawin natin sa gabi. Pero siguro may mga pagkakataon yung ibang ibang areas depending on the design of the distribution network may ibang tatamaan na during peak,” said Ferdinand Dela Cruz of Manila Water.
(Our standing order is to implement it as much as possible in the evening. But there would be instances in some areas depending on the design of the distribution network that the interruptions would be during peak hours.)
If Angat Dam’s water level reaches 155 meters this year, it will be the lowest in history according to the NWRB as compared to 157 meters, the lowest recorded in 2010. (with reports from Joan Nano)

MANILA, Philippines – As of 6:00 a.m. Wednesday (June 12) water level in Angat Dam hit 164.48 meters, still lower than its minimum operating level of 180 meters.
According to the state weather bureau, PAGASA, this is nearing the lowest level recorded in July 2014 when the water level dipped to 162.74 meters.
“Meron kaming na-observe na malalakas na rainfall sa may bandang Zambales, minsan sa bandang Bicol, Cavite, Laguna which is malayo naman sa watershed ng Angat Dam,” PAGASA Hydrologist Elmer Caringal said.
(We have observed heavy rainfall in areas near Zambales, occasionally in Bicol, Cavite, and Laguna which are far from Angat Dam watershed.)
According to the National Water Resources Board (NWRB) Executive Director Sevillo David Jr., Angat Dam will not provide for irrigation this month of June per protocol of the agency which prioritizes the water requirement for Metro Manila.
“Sa protocol (kapag) below 180 meters (ay) priority ang water supply for evaluation ng Board if magre-release for irrigation,” David said.
At present, Angat Dam’s allocation for Metro Manila stays at 46 cubic meters per second.
The National Irrigation Administration (NIA) noted, meanwhile, that farmers in Bulacan and Pampanga are expected to begin cropping season in August when they will be needing water from Angat Dam.
Still, the agency expects cropping to be ahead of schedule with the coming rainy season.
The lowest water level in Angat Dam was recorded in July 2010 when water reserve dipped further to 157.56 meters. (with reports from Rey Pelayo)
