Many people moving to Portugal are surprised to discover that houses can feel cold during winter. Because the country is known for its mild climate and sunny weather, many expats assume that heating will not be necessary.
However, indoor temperatures can sometimes feel colder than expected. Even when outdoor temperatures are moderate, houses without proper heating systems can become uncomfortable during winter evenings and nights.
Understanding how Portuguese homes behave in winter helps homeowners decide whether installing a heating system is necessary.
In many parts of Portugal, winter comfort depends more on the house itself than on outdoor temperatures.
Why Houses in Portugal Can Feel Cold
Several factors contribute to why houses in Portugal can feel colder than expected during winter.
Many traditional homes were designed primarily for summer comfort. Thick walls, tiled floors and natural ventilation help keep interiors cool during hot weather, but these same features can make houses feel colder when temperatures drop. Older houses also often have lower insulation levels compared with homes in northern Europe. Without insulation or heating, indoor temperatures can quickly follow outdoor conditions.
As a result, many houses rely on heating appliances to create comfortable living spaces during winter.
Winter Temperatures in Portugal
Portugal’s winter climate varies depending on the region.
Coastal areas such as Lisbon and the Algarve tend to have milder winters, while inland and northern regions can experience colder temperatures.
Typical winter temperatures include:
• Algarve: 8–16°C
• Lisbon region: 7–15°C
• Central Portugal: 5–13°C
• Northern Portugal: 4–12°C
While these temperatures may appear moderate, indoor spaces can still feel cold without heating, especially during the evening.
How Homes Are Usually Heated
Instead of central heating systems, many Portuguese homes use room-based heating appliances that warm the areas where people spend most of their time.
Common solutions include:
• Wood stoves
• Pellet stoves
• Fireplace inserts
• Wood cook stoves
• Air conditioning with heating mode
These systems allow homeowners to focus heating on living rooms or open-plan spaces rather than heating the entire house continuously.
Heating the Living Area
In many Portuguese homes, the living room becomes the main heated area during winter. This is where families gather in the evening, watch television or spend time together.
Installing a heating appliance in this space often provides enough warmth for everyday comfort. For this reason, wood stoves and pellet stoves are widely used across Portugal, as they can quickly warm large living areas.
Do Expats Usually Install Heating?
Many international homeowners who buy property in Portugal decide to install heating systems after experiencing their first winter in the house.
While some modern homes already include heat pumps or underfloor heating, older houses often require additional heating appliances. Installing a wood stove, pellet stove or fireplace insert is often one of the simplest and most effective ways to improve winter comfort.
