MANILA – The Metropolitan Waterworks and Sewerage System (MWSS) said water levels at Angat Dam are expected to remain within safe levels in the coming months despite rising temperatures with the end of the northeast monsoon or amihan.

MWSS manager Patrick Dizon said current projections show that the dam’s elevation will not fall to critical levels.

“Although mababa ang water level ng tubig ngayon, di naman natin nakikita na umabot sa critical level na 160 meters,” Dizon said during a public briefing.

He added that the water level is unlikely to drop to the same critical point recorded during the 2010 El Niño.

Angat Dam supplies around 90 percent of water requirements in Metro Manila, as well as parts of Rizal and Cavite.

Dizon assured the public that water supply remains sufficient, noting that additional reserves are available in surrounding watersheds.

As of Tuesday morning, the dam’s water level stood at 199.86 meters.

He explained that a decline in dam levels is typical during periods of higher temperatures.

Earlier, Philippine Atmospheric Geophysical and Astronomical Services Administration (PAGASA) said temperatures are expected to peak in April and May.

PAGASA senior weather specialist Joseph Bascocillo said temperatures in Metro Manila could reach between 35°C and 39°C in April, and 35.5°C to 37.6°C in May.

Authorities advised the public to take precautions against heat stress and to stay hydrated.

PAGASA earlier said it is monitoring a possible El Niño, which has over a 50 percent chance of developing between July and September.

According to PAGASA Climate Monitoring and Prediction Section chief Ana Liza Solis, the phenomenon could weaken typhoons and the southwest monsoon or habagat, potentially worsening dry conditions toward the end of the year and into the summer of 2027.

“This could affect the high temperatures we may experience during the next warm and dry season in 2027, so we need to monitor closely,” Solis said.
