Rainy Season in Panama: A Practical Guide for Expats for October and November 2026

Reside Panama

If it's your first rainy season in Panama, you'll learn quickly that afternoon downpours are part of the routine. In most of the country, the rainy season runs roughly from May to November, and October and November are usually the wettest months. Most days start sunny and end with a strong storm, so a little planning goes a long way.

This year has its own twists, so here's what to know and how to prepare.

What's different in 2026: El Niño

Panama's weather institute, IMHPA, has an El Niño alert active. According to its forecasts reported by Infobae:

Much of the Pacific side (including Panama City, Panamá Oeste, Coclé, Veraguas and Chiriquí) could see 20–40% less rain than normal in the August–October period.
The Caribbean side and highlands, such as Bocas del Toro, the Chiriquí highlands and Guna Yala, could see 15–25% more rain.
Temperatures may run 2–3 °C above normal, with a heat index above 38 °C.
In October and November, Panama could feel indirect effects from at least one tropical system.

In other words: even in a drier-than-usual year, strong storms are still expected. In early September, IMHPA and SINAPROC issued a 72-hour nationwide rain and storm watch because of a tropical wave.

How to prepare your home

Check drains, balconies and windows before the heaviest weeks. Ask your building management if they've cleaned roof and parking drains.
Have a water reserve. Many buildings have tanks, but if you live in a house, consider a reserve tank. It also helps during IDAAN outages.
Protect your electronics with surge protectors. Power cuts and lightning are more common during storms.
Keep a basic emergency kit: flashlight, batteries, power bank, drinking water, basic medicine and copies of your documents.
Watch for humidity and mold in closets and shoes. A dehumidifier or regular air conditioning use helps a lot.

On the road

Avoid driving during heavy downpours if you can. Some streets in Panama City flood quickly.
Never cross flooded streets, rivers or streams, even if they look shallow.
Add extra time to your commute in the afternoons. Traffic gets much slower when it rains.

Water outages: how to stay informed

The national water utility, IDAAN, regularly schedules maintenance at treatment plants. For example, for the week of September 28 to October 4, 2026, it announced work at plants in Chiriquí, Los Santos, Herrera, Bocas del Toro and Panamá Oeste. IDAAN posts these notices on its X account @IDAANinforma, and you can also report problems through 311.

What this means if you're...

...new to Panama: Get used to planning errands in the morning. Afternoons are when storms usually hit.

...looking for a place to live: Ask about flooding history in the area, whether the building has a water tank and backup generator, and how the parking area handles heavy rain. Visit the property after a storm if you can.

...living in Bocas del Toro or the highlands: This year you may see more rain than usual, so stay especially alert to official notices.
