Last updated on August 12th, 2025 at 11:33 am

The rainy season in the Philippines typically starts in June and lasts until November, with heavy rainfall, thunderstorms, and even typhoons. While it brings much-needed water for crops and relief from the summer heat, it also brings challenges such as flooding, disease outbreaks, and increased risk of pest infestations.

This guide will help you stay safe and healthy throughout the rainy season using government-recommended practices and accessible resources.

What to Expect During the Rainy Season

According to the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA), the rainy season begins when five consecutive days of rainfall with a total of at least 25 mm occur. You can track weather updates from PAGASA’s official website.

Here’s what usually happens during this season:

• Frequent thunderstorms

• Sudden flash floods

• Waterborne diseases

• Mosquito-borne illnesses like dengue

• Mold growth indoors

• Increased pest activity

Tips to Stay Safe During the Rainy Season

1. Monitor Weather Reports Regularly

Check daily forecasts on the PAGASA website or follow them on Facebook and X (formerly Twitter). Early alerts help you plan better and avoid danger zones.

2. Prepare an Emergency Go Bag

The National Disaster Risk Reduction and Management Council (NDRRMC) recommends a go bag with essentials such as:

• Bottled water and canned goods

• Flashlight and batteries

• Basic first-aid kit

• Extra clothes and face masks

• Important documents in waterproof pouches

• Power bank

For a full list, visit NDRRMC’s preparedness page.

3. Keep Your Home Dry and Pest-Free

Excess moisture from rain can attract cockroaches, ants, termites, and rats. Ensure your home is protected by:

• Sealing cracks in walls or floors

• Keeping storage areas dry and clutter-free

• Fixing leaking pipes and roofs

• Cleaning gutters and drainage

For professional help, consider contacting licensed pest control providers such as Environet Pest Control, especially if you’re dealing with termite infestations after continuous rainfall.

4. Prevent Dengue and Mosquito-Borne Diseases

The Department of Health (DOH) warns of increased dengue cases during the rainy season due to stagnant water where mosquitoes breed. Follow these steps:

• Empty water containers and flower pots weekly

• Use mosquito nets and insect repellents

• Join barangay clean-up drives

• Get updates on dengue hot spots from DOH Dengue Updates.

5. Avoid Flood-Prone Areas

The Metropolitan Manila Development Authority (MMDA) updates its flood monitoring maps regularly. Use their app or website to avoid high-risk roads.

The DPWH also posts road conditions and closures due to landslides or flooding. Stay updated here.

6. Stay Healthy to Fight Infections

Cold, cough, and waterborne diseases like leptospirosis are common during this season. The DOH recommends:

• Drinking boiled or purified water

• Washing hands often

• Wearing boots in floodwater

• Visiting the nearest health center if symptoms arise

Use the DOH Health Facility Locator to find nearby clinics and hospitals.

7. Protect Your Appliances and Electronics

Power outages and voltage surges are common. Unplug appliances during heavy storms, and consider using surge protectors to prevent damage.

Also, elevate power strips and electronics away from the floor to avoid water exposure.
