Rising Heat Index in the Philippines: Class Cancellations and the Start of Summer
As the Philippines transitions from the northeast monsoon season to the warmer months, the Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA) has issued warnings about rising temperatures and heat index levels. With temperatures expected to climb, several schools have preemptively canceled face-to-face classes to ensure the safety of students and staff.
The Heat Index and Its Implications
The heat index, often referred to as the “feels-like” temperature, considers both air temperature and humidity. PAGASA has started releasing daily heat index readings as of March 1, 2025, signaling the official shift to summer. High heat index levels can lead to heat-related illnesses such as heat exhaustion and heatstroke, especially for children, the elderly, and those with preexisting health conditions.
On March 3, several schools and local government units announced class suspensions due to the extreme heat forecast. This decision reflects growing concerns over student welfare, as prolonged exposure to high temperatures can cause dehydration, dizziness, and fatigue, making learning conditions unsafe.
Why Is the Temperature Rising?
The transition from the northeast monsoon (Amihan) to the dry season brings significant changes in climate patterns. Amihan, which brings cooler temperatures and moderate weather from November to February, has started to weaken. As a result, the country is now shifting to a period dominated by high temperatures and minimal rainfall, characteristics of the dry season.
PAGASA has also pointed out that climate change plays a role in amplifying extreme weather patterns, making summers hotter and heatwaves more frequent. Urban areas, particularly Metro Manila, are expected to experience higher heat indexes due to the urban heat island effect, where concrete structures and lack of green spaces trap heat.
How to Stay Safe During the Heatwave
With rising temperatures, it is essential to take precautionary measures to avoid heat-related illnesses:
- Stay Hydrated – Drink plenty of water throughout the day and avoid caffeinated or alcoholic beverages.
- Wear Light Clothing – Opt for light-colored, breathable fabrics to stay cool.
- Limit Outdoor Activities – Avoid strenuous activities under direct sunlight, especially between 10 AM and 4 PM when temperatures peak.
- Use Sun Protection – Apply sunscreen, wear a hat, and use an umbrella for additional shade.
- Monitor Heat Advisories – Stay updated with PAGASA’s heat index forecasts and follow advisories regarding safety measures and class suspensions.
Looking Ahead
As the Philippines enters its hottest months, it is crucial for the government, schools, and communities to take proactive steps to mitigate the effects of rising temperatures. Public awareness campaigns, improved school facilities with proper ventilation, and flexible learning arrangements may help ensure student safety during extreme heat conditions.
With summer officially here, Filipinos are urged to brace themselves for soaring temperatures and to prioritize health and safety as the heat intensifies in the coming weeks.
