The Philippines sits in the world's most active typhoon belt. Every year, around 20 tropical cyclones enter or form within Philippine waters — and knowing PAGASA's signal system could save your life. Here's everything you need before the next bagyo.
PAGASA Tropical Cyclone Warning Signals
PAGASA issues Tropical Cyclone Warning Signals (TCWS) to warn communities of incoming wind hazards. Higher signal numbers mean stronger winds and a shorter time to prepare or evacuate.
| Signal No. | Wind Speed | What It Means | Time to Impact | Action |
|---|---|---|---|---|
|
#1
Signal #1
|
30–60 kph Gusts up to 75 kph |
Typhoon possible within the forecast area | 36 hours | Monitor updates |
|
#2
Signal #2
|
61–120 kph Gusts up to 150 kph |
Typhoon likely to make landfall | 24 hours | Prepare go-bag |
|
#3
Signal #3
|
121–170 kph Gusts up to 220 kph |
Destructive typhoon approaching | 18 hours | Ready to evacuate |
|
#4
Signal #4
|
171–220 kph Gusts up to 285 kph |
Very destructive typhoon imminent | 12 hours | Evacuate now |
|
#5
Signal #5
|
>220 kph Gusts exceed 285 kph |
Catastrophic / super typhoon | 12 hours | Mandatory evacuation |

Monthly Activity Breakdown
While typhoons can strike any month, activity peaks sharply from August through October. Here's what to expect each month of the year.
Typhoon activity begins picking up as warm sea-surface temperatures in the Western Pacific fuel tropical cyclone formation. Luzon is first to become vulnerable.
Sea surface temperatures reach their annual high and atmospheric conditions are most favorable for typhoon development. An average of 3–4 storms are active in Philippine waters each month during this period.
Activity starts to decrease but late-season typhoons can be especially dangerous — Typhoon Yolanda (Haiyan) struck on November 8, 2013. Never drop your guard until December.
Typhoon Preparedness Guide
Knowing what to do at each stage of a typhoon is the most important thing you can prepare. Follow these NDRRMC-aligned steps to protect yourself and your family.
The Deadliest Typhoon Hazard
Storm surge — not wind — is the leading cause of typhoon deaths in the Philippines. If you live near the coast, understanding this hazard is non-negotiable.
On November 8, 2013, Super Typhoon Yolanda made landfall in Leyte and Eastern Samar with storm surge waves reaching up to 7 meters — as tall as a 2-story building. Over 6,300 lives were lost, the majority killed not by wind but by the sudden surge of ocean water that swept entire neighborhoods off the map. Many victims were told to shelter in concrete buildings — those buildings were not high enough. The lesson: if a Signal 4–5 typhoon approaches your coastal area, evacuate to high ground, not just a stronger structure.
Storm surge is an abnormal rise of seawater pushed onshore by a typhoon's powerful winds and low atmospheric pressure. It is separate from typhoon-driven rainfall floods.
During a strong typhoon, winds essentially push the ocean toward the coast. This wall of water can rise 3–7 meters high and travel several kilometers inland within minutes — far faster than any person can outrun.
Storm surge hazard areas cover all coastlines and areas within 1–3 kilometers of the sea, especially in bays, inlets, and low-lying coastal plains.
Philippine Typhoon History
Understanding how past typhoons unfolded — and what made them so catastrophic — is the best preparation for future storms.
Yolanda, Odette, and Reming's deadliest impact came from water — not wind. Coastal residents must always prioritize inland evacuation, not just shelter-in-place.
Ondoy was only a tropical storm at landfall, but its extreme rainfall (451mm in 6 hours over Metro Manila) caused the worst urban flooding in Philippine history. Signal level ≠ flood risk.
Pablo's landslides in Compostela Valley and Reming's lahars from Mayon show that typhoons trigger secondary hazards. Know your area's landslide and volcano risk, not just flood risk.

Everything Filipinos ask about typhoon season, PAGASA signals, and how to stay safe.
| Tropical Depression | Below 63 kph |
| Tropical Storm | 63–88 kph |
| Severe Tropical Storm | 89–117 kph |
| Typhoon | 118–220 kph |
| Super Typhoon | Above 220 kph |
Even tropical depressions can cause deadly floods and landslides in the Philippines, especially when they interact with the southwest monsoon (habagat). Never ignore a weather advisory regardless of the storm's classification.
Important: Document all damage with photos before cleaning up. Report to your barangay within 72 hours of the typhoon to be included in NDRRMC's affected families list.
