If you are considering building a home on the Oaxacan Pacific coast, the question of building a resilient home for the Oaxacan coast — one that handles hurricane season — has to be part of the conversation from the beginning.
I am not going to tell you the coast is dangerous and leave it at that. I am also not going to pretend the risk does not exist. What I want to do is give you a clear picture of what the actual exposure is here, how we build in response to it, and why certain materials and design choices make a genuine difference.
The actual hurricane risk on the Oaxaca coast
The Pacific coast of Oaxaca sits within the eastern Pacific hurricane basin. Season runs June through October, with peak activity in August and September. Most storms that affect this coastline are Category 1 or 2 at landfall; Category 3 systems make landfall occasionally. Category 4 and 5 are possible but significantly less common, and direct hits from major hurricanes are rare rather than routine.
This is not the same risk profile as the Gulf coast of Mexico or the Caribbean. It is a real risk, and it should shape how you build. But it is a manageable one, and the history of building in this region is a history of people managing it — through design, materials, and post-event thinking, which I will come back to.
Structural approaches
Reinforced concrete tie-beams
Adobe walls are thermally excellent — our preferred wall material for the reasons described in the building with the climate post — but adobe without structural reinforcement behaves poorly under lateral load, which is what a hurricane produces. The solution is not to abandon adobe for concrete block. It is to tie the adobe together with reinforced concrete at the base and top of the walls.
A ring beam at the top — a continuous reinforced concrete element running around the entire perimeter — ties the walls into a single system. Under wind load, the walls act as a unit rather than as independent elements that can separate. This is standard practice in earthquake country and transfers directly to hurricane resilience.
Hip roofs over gable ends
A gable roof has a flat end wall that presents a large area to wind. Under hurricane conditions, that end wall generates significant uplift and lateral force — one of the most common failure points in tropical roof structures.
A hip roof eliminates the gable end entirely. All four sides slope down, so wind always meets an angled surface. Hip roofs were not invented as a hurricane strategy, but their prevalence in traditional tropical architecture reflects generations of observed performance.
Roof anchoring
A roof that is well-built but poorly connected to the walls will lift off as a unit under strong wind. This failure mode is extremely common and extremely preventable. Hurricane straps — metal connectors that tie roof rafters to wall plates — are standard where building codes take wind seriously. In poured concrete ring beams, the roof structure can be embedded directly into the concrete, creating a continuous connection stronger than mechanical fasteners alone.
Every building at Rancho de las Estrellas uses anchored roof connections. This is not optional.
Overhang limits on exposed sides
Deep overhangs are good for passive cooling — they block summer sun and protect walls from rain. But an overhang also creates uplift surface. On the windward side of a building, an overhang acts like a wing: wind moving under it generates lift that works against the roof anchoring. Beyond about 60 centimeters on exposed sides, this uplift force can overwhelm conventional connections.
We limit overhangs on the sides of a building that face predominant storm wind directions, and we detail the connections on longer overhangs with additional anchoring. This is the kind of tradeoff that has to be designed in consciously rather than discovered after the fact.
Windows and glazing
Windows are a vulnerability in two ways: as structural openings that alter wind pressure distribution across the building envelope, and as glass that can fail under impact from wind-borne debris. Impact-resistant glazing is more expensive than standard glass but significantly reduces the second risk. Shutters — either traditional or hurricane-rated — address both: they protect the glass and reduce the pressure differential that the opening creates.
Small, well-placed windows also perform better than large glazed surfaces. A building designed around cross-ventilation rather than glass walls is inherently better positioned for hurricane resistance, which is another convergence between the passive cooling approach and the resilience approach.
Materials and their behavior under storm conditions
Adobe
A properly tied adobe wall is more resilient in a storm than most people expect. The density of adobe gives it inertia against lateral load, and thick walls distribute any point of failure over a large section rather than concentrating it at a single joint. When the ring beam is in place, the walls do not separate or rotate.
Adobe does have a failure mode under flooding: prolonged saturation weakens the material. This is why foundation design matters — getting adobe above the moisture line with a river stone or concrete base, and ensuring drainage away from the building, is the protection.
Palm thatch
This one surprises people. Thatch seems fragile. But a traditional palm thatch roof has a property that tile and metal do not: when it fails, it fails gracefully. Sections damaged in a storm can be replaced with local materials and local labor, often within days. A tile roof that loses sections becomes inaccessible until specialized materials arrive. A metal roof that folds requires structural assessment and replacement.
The thatch roof can be re-thatched. Post-hurricane repair timelines in remote areas depend heavily on what materials and skills are locally available. Both are available here, and we think about this explicitly when recommending materials.
Local hardwood
Properly specified local hardwood has high strength and flexibility relative to its weight, and species selected for structural use here are chosen for their track record in this climate — decades of observed performance, not specifications imported from another region. Hardwood also gives more warning before failure than concrete or masonry: you can see the distortion before the element gives way.
Ground-floor flooding
The Oaxacan coast sees storm surge and flooding during major events. Design for it rather than hoping it will not happen to your site. This means:
- Understanding the elevation of your lot above sea level and above the probable high water line for a significant storm
- Designing the ground floor with materials that can be dried and cleaned rather than replaced after flooding
- Locating critical systems — electrical panels, water storage, documentation storage — at heights that are above probable flood elevation
- Thinking through drainage: where does the water go when it arrives, and does your design channel it away from the building or toward it
At Rancho de las Estrellas we have assessed the elevation and drainage characteristics of each lot as part of the planning process. This is part of the conversation during the lot selection stage.
Learning from what already works here
The vernacular palapa — palm thatch on wood or bamboo posts — has been the dominant building form on this coast for centuries. It is not structurally sophisticated by engineering standards. It also keeps getting rebuilt after every storm, because the design, the materials, and the knowledge to repair it are all available in place.
That is a form of resilience a custom concrete building from another tradition may not have. We study the vernacular forms seriously — they carry generations of observed performance that no engineering manual fully captures — and we try to understand what worked and why before proposing anything different.
Post-hurricane design thinking
One question I ask when reviewing a building design is: what breaks first, and can you fix it with what is available here? A building that requires specialized contractors or imported materials sits damaged for longer than it needs to. One whose failure points are addressable with local materials and local skills is back in service quickly. This is not a reason to build primitively. It is a reason to think about your repair supply chain before you need it.
Building on the Oaxacan coast requires this conversation up front. Not as a deterrent, but as part of the design brief. The buildings that perform well here — that are cool in summer, structurally sound in storms, and repairable after damage — are the buildings that took these questions seriously at the design stage.
You can read more about our full construction approach, guidelines, and material standards on the build page. If you want to understand the community context before getting into the construction details, the about page and vision page are good starting points. And if you want to come and see the land — including existing structures that demonstrate these principles in place — the visit page is where that starts.
The coast here is beautiful and real. So is the weather. Building well means accepting both.
