Hurricane Season
The Atlantic hurricane season from June to November brings the greatest risk, with peak activity in August-October. Category 4-5 storms can devastate entire islands.

Weather Risk Management for Caribbean Construction
The Caribbean sits in the heart of the Atlantic hurricane belt. With a six-month storm season, year-round humidity, and coastal exposure on every site, weather risk is the defining challenge for Caribbean construction.
Understanding the Caribbean Construction Climate
The Caribbean has a tropical maritime climate with year-round warmth averaging 25-30°C. The hurricane season from June to November dominates planning, with peak activity in August-October. Tropical storms can form rapidly and intensify quickly, giving limited preparation time.
Distinct wet and dry seasons shape construction calendars. The wet season (May-November) coincides with hurricane season, creating a double challenge. High humidity year-round affects concrete curing, steel corrosion from salt spray, and worker comfort.
Island construction faces unique logistics challenges when storms disrupt shipping routes. Coastal exposure means every project site faces wind, wave, and salt spray risks that mainland projects rarely encounter.
Key Weather Challenges for Caribbean Construction
Six critical weather risks that impact Caribbean construction projects, each quantifiable with WeatherWise.
Tropical Storms
Even storms below hurricane strength bring dangerous rainfall, flooding, and wind that halt construction and damage partially completed structures.
Coastal Exposure
Every Caribbean construction site is relatively close to the coast, facing salt spray corrosion, wave action, and storm surge risks.
High Humidity
Year-round humidity exceeding 80% affects concrete curing times, accelerates steel corrosion, and creates challenging working conditions.
Flooding
Intense tropical rainfall combined with limited drainage on islands creates rapid flash flooding that can inundate construction sites.
Limited Windows
The overlap of wet season and hurricane season creates a narrow optimal construction window, intensifying scheduling pressure.
Major Cities & Construction Hubs
Weather risk varies across the Caribbean islands. Here are the key construction markets and their climate challenges.
Kingston, Jamaica
Tropical marine climate with a distinct hurricane season from June through November. Heavy rainfall during the wet season causes frequent flooding, while Kingston's position on the south coast exposes it to Caribbean Sea storm surges.
Nassau, Bahamas
Tropical savanna climate with direct hurricane exposure due to the low-lying island geography. Storm surge is a major risk with elevations rarely exceeding a few metres, and salt spray corrosion accelerates deterioration of exposed construction materials.
Port of Spain, Trinidad
Tropical climate with a pronounced wet season from June to December. Located south of the main hurricane belt but still vulnerable to tropical storms, with intense rainfall and flooding the primary weather risks for construction operations.
Santo Domingo, Dominican Republic
Tropical rainforest climate with frequent hurricane hits and heavy seasonal rainfall. The city's coastal position and river system create compound flooding risks from both storm surge and riverine overflow during major weather events.
San Juan, Puerto Rico
Tropical marine climate with significant hurricane exposure. The island's mountainous terrain intensifies rainfall from tropical systems, while persistent trade winds and salt-laden air affect material selection and structural design requirements.
Bridgetown, Barbados
Tropical marine climate moderated by northeast trade winds. Located at the eastern edge of the Caribbean hurricane belt with exposure to Atlantic swells. Coral limestone geology creates unique foundation conditions compounded by seasonal rainfall.
Notable Construction Projects
Caribbean construction faces unique island challenges. Jamaica's logistics hub development in Kingston contends with hurricane season and coastal exposure. Nassau's cruise port redevelopment manages storm surge risk on low-lying terrain. Puerto Rico's power grid modernisation rebuilds infrastructure devastated by hurricanes. Trinidad's industrial infrastructure expansion navigates wet season flooding, and the Dominican Republic's tourism development programme builds resilient coastal structures.

Frequently Asked Questions
How should teams plan around hurricane season?
Hurricane season runs June-November with peak August-October. WeatherWise analyses historical storm tracks and wind speeds at your coordinates to quantify monthly risk, helping teams schedule critical activities during lower-risk windows.
What are the challenges of post-storm construction?
Post-storm construction faces debris clearance, supply chain disruption from damaged ports, waterlogged sites, and potential structural damage to partially completed works. WeatherWise helps plan realistic recovery timelines.
How does insurance relate to weather risk?
Caribbean construction insurance premiums reflect hurricane exposure. WeatherWise provides the historical data insurers need to assess your specific site risk accurately.
When is the best time for Caribbean construction?
December through April offers the driest conditions and lowest storm risk. However, the construction window is short, so projects spanning hurricane season need robust weather contingency.
What data is available for Caribbean islands?
ERA-5 provides full coverage of all Caribbean islands with 45+ years of hourly data including 80+ weather variables, tropical storm history, and sea-state conditions.
