The hurricane season in the Dominican Republic runs from June 1 to November 30, with peak activity between August and October. This period requires preparation for both those living here and those planning to build or invest in vulnerable areas such as Las Terrenas. Here is a detailed guide to recent storms, how to protect yourself and what to consider when designing tropical weather resistant homes.
When exactly is hurricane season in the Dominican Republic?
During the official Atlantic season – which runs from June 1 to November 30 – the country is under the influence of possible storms and hurricanes. Although the most intense systems usually form between August and October, it is advisable to prepare for them as early as June to have time to react.
Recent hurricane seasons: recent hurricanes that have affected the country
In recent years, several cyclones have impacted or brushed against the Dominican Republic:
- Ernesto (August 2024): Category 1, with winds of up to 126 km/h and heavy rains in regions such as El Valle and Yuma.
- Oscar (October 2024): reached 139 km/h, affecting areas of Yuma and Cibao with light flooding.
- Sara and Rafael also passed nearby, generating heavy rains and localized power outages.
- In September 2022, Hurricane Fiona (category 1) caused flooding, landslides and damages estimated at USD 375 million in critical infrastructure.
Although more destructive hurricanes such as Irma, Maria or David did not directly impact the DR, their outer bands caused rainfall, power outages and indirect damage in previous years.
Key considerations if you are in the DR during a hurricane
If you are in the country during this period:
- Stay informed with official forecasts from the National Hurricane Center (NHC) or local information.
- Identify nearby safe havens and have a family emergency plan.
- Secure windows, doors, loose objects on patios or decks, and follow evacuation orders if directed by authorities.
- During the storm, avoid going down to basement levels or flood areas; after the storm, check for leaks or structural damage.
Building hurricane-resistant housing during hurricane season
Location and type of land
Houses located on hills or steep slopes present a greater risk of landslides or erosion. It is preferable to choose flat land or to carry out adequate containment works if building on slopes.
Strong structural design
- Deep foundations, use of anchored loads, and reinforced foundations.
- Anticyclonic shutters or impact shutters for windows: protect against high winds and debris.
- Gable roofs, steel connections and resistant materials such as metal panels or reinforced shingles.
Suitable materials
- Reinforced concrete and reinforced blocks (with vertical and horizontal ribs).
- Metal structures or treated wood, always properly anchored.
- Bioclimatic design to favor cross ventilation without direct exposure to the wind.
Soil preparation and drainage
- Perimeter drainage systems to avoid soil saturation.
- Lines, ditches and slopes that direct water away from the foundation.
- Well-planned earthworks to avoid erosion during rainy seasons.
Practical checklist for hurricane-safe homes
| Requirement | Key recommendation |
|---|---|
| Location | Avoid steep hills or unstable terrain. |
| Foundations | Deep and anchored to the subsoil |
| Coatings | Wind and moisture resistant materials |
| Windows and doors | Anticyclonic shutters or reinforced glass |
| Roofs | Secure and well-anchored design, minimal slope |
| Drainage and containment | Adequate systems, ditches and perimeter drains |
| Outdoor furniture | Must be stored or secured before a storm |
