Mauritius
Climate
A warm tropical maritime climate, generally wetter in the central uplands and on windward slopes. Humidity, intense rain, cyclone-season weather and coastal salt influence design and upkeep.
Geographic hazards
- Tropical cyclones
Check cyclone wind design, roof-to-wall connections, opening protection and exposed equipment. A strong wall system still needs a continuous load path to the foundations.
- Heavy rain & local flooding
Investigate runoff, drainage channels, floor levels and road access. Roof waterproofing and stormwater capacity need attention before the wet season.
- Coastal flooding & erosion
Sea-facing plots need local shoreline, surge and setback information. Assess corrosion and access as well as the building elevation.
- Slope movement & heat
Steep, wet upland sites can require geotechnical investigation. Shade and ventilation help manage heat and humidity but cannot resolve unsafe ground.
Insects and rot
Ask a local specialist about termites and other wood-destroying insects. Humid conditions, leaking roofs and concealed damp can lead to timber decay. Inspect joinery and roof elements even where the main walls are concrete.
Best-fit building approaches
- Engineered concrete & reinforced masonry
Can suit cyclone-prone exposure where wind engineering, roof connections, waterproofing and corrosion protection are verified. Heavy construction is not automatically cyclone-resistant.
Read the concrete & block guide - Engineered timber framing
A properly engineered timber structure can be an alternative with cyclone fixings, suitable pest treatment and a ventilated, weather-resistant envelope. Confirm local approvals and maintenance capacity.

Buyer checks
Review cyclone design and roof/foundation connections.
Check local flood, shoreline and slope information plus wet-weather access.
Inspect waterproofing, timber pests and corrosion, and verify insurance options.

Print or save as PDF using your browser. Includes country guidance, official links and blank spaces for handwritten notes. No property details are saved.
These official resources help you ask better questions; they do not provide a parcel-level risk assessment. A map does not guarantee safety, and an unmapped or blank area does not mean no hazard. We do not assign automatic property risk scores.
- Collect the address, region/municipality, cadastral parcel reference and coordinates from the seller or surveyor. Check the map pin against the actual plot, not just the postcode or village centre.
- Open the relevant resource below. Where there is no address search, use coordinates, local landmarks or the named regional map sheet. Check the plot, access roads and evacuation routes.
- Read the legend, scale, publication date, model scenario and coverage. A “100-year” event is a probability scenario, not a promise of one event per century. Check current official warnings separately before visiting.
- Ask the responsible authority for the latest local study and restrictions. Give the findings to a qualified surveyor, structural/geotechnical engineer and insurer before relying on them in a purchase.

NDRRMC — flood-prone critical sites
Authority: National Disaster Risk Reduction and Management Centre, Mauritius
Hazards: Known flood-prone sites and local flood-planning context
Coverage: Mauritius; listed mainland sites, not a complete map of Mauritius and Rodrigues.
How to locate the property: Read the critical-site information and identify the local council/region. Give NDRRMC and the council your address, parcel plan and coordinates and request the Land Drainage Authority’s current catchment maps.
Limits: The page describes historical site inventories and response planning, not a current parcel viewer. No complete reliable public address-level flood/surge, cyclone, landslide or wildfire map was verified here; absence from a site list is not evidence of safety.
Editorial review: 2026-10-14. Published edition [recorded]: Critical-sites inventory collected March 2019; an inventory, not a published parcel hazard map. This is not a live status or property assessment.
Confirm locally — including gaps in mapping
Request flood/catchment information from the Land Drainage Authority and municipal/district council; coastal and slope constraints from the responsible planning/environment services; and cyclone/evacuation advice from NDRRMC and Mauritius Meteorological Services. For Rodrigues, contact the Rodrigues Regional Assembly and its local disaster-management services rather than applying mainland studies.
