Published on October 2, 2025 and written by Cyril Jarnias

Portugal, with its Mediterranean climate and varied landscapes, attracts many expatriates seeking a better quality of life. However, adapting to a new climate can present challenges, even in a country known for its pleasant lifestyle. Here is a comprehensive guide to help you acclimate and fully enjoy your new life under the Portuguese sun.

Understanding the Portuguese Climate

Portugal enjoys a Mediterranean climate characterized by hot, dry summers and mild, wet winters. However, there are significant regional variations to consider:

The Atlantic Coast: It benefits from a temperate climate with pleasant summers and mild winters. Summer temperatures typically range between 68°F and 86°F, while in winter they stay between 50°F and 59°F.

The Interior: Inland regions experience hotter summers, with temperatures that can exceed 95°F, and colder winters, where the mercury can drop below 32°F in some mountainous areas.

The Algarve: This southern region of Portugal is famous for its particularly mild and sunny climate year-round, with over 300 days of sunshine per year and winter temperatures rarely falling below 50°F.

Impacts of Climate on Health and Well-being

Adapting to the Portuguese climate can have repercussions on your health and well-being. Here are some points to monitor:

Dehydration and Heatstroke: The hot, dry summers can increase the risk of dehydration, especially for those unaccustomed to this type of climate. It’s crucial to drink enough water and limit sun exposure during the hottest hours.

Seasonal Allergies: Portugal experiences intense pollen periods, particularly in spring. Expatriates with allergies should consult a local doctor to adjust their treatment if necessary.

Winter Humidity: Although winters are generally mild, humidity can be high, which may exacerbate certain respiratory or rheumatic issues.

UV Exposure: Significant sunshine throughout the year requires adequate sun protection to prevent sunburn and long-term risks associated with UV exposure.

Strategies for Adapting to the Portuguese Climate

To fully enjoy your new life in Portugal, here are some essential adaptation strategies:

1. Adopt the Local Rhythm

The Portuguese have adapted their lifestyle to the local climate. Follow their example by:

– Taking a siesta during the hottest hours of the day, especially in summer. – Enjoying cooler evenings for outdoor activities. – Adopting later meal times, typical of Mediterranean culture.

2. Hydrate Properly

Heat and sun can quickly dehydrate the body. Make sure to:

– Drink water regularly, even if you’re not thirsty. – Consume fruits and vegetables rich in water. – Limit alcohol and caffeine intake, which can increase dehydration.

3. Protect Yourself from the Sun

Portugal’s generous sunshine requires adequate protection:

– Apply high-SPF sunscreen (SPF 30 minimum) year-round. – Wear light, covering clothing and a wide-brimmed hat. – Invest in quality sunglasses to protect your eyes.

4. Adapt Your Diet

The climate naturally influences eating habits. In Portugal:

– Opt for light, fresh meals during the hot months. – Discover the local cuisine, rich in fish and seafood, which are excellent for health. – Enjoy seasonal fruits and vegetables, which are particularly flavorful and abundant.

5. Stay Active, but Smartly

The Portuguese climate promotes an active lifestyle, but with some precautions:

– Schedule your sports activities early in the morning or late in the day to avoid the hottest hours. – Discover water sports to cool off while staying active. – Explore the country’s many hiking trails, adjusting your outings according to the season.

Adapting Your Home for Climate Comfort

Your living space plays a crucial role in your adaptation to the climate. Here’s how to optimize your home:

For Summer

– Install exterior blinds or shutters to block heat. – Invest in an air conditioning system or fans, depending on your preferences and budget. – Create cross-ventilation by opening opposite windows early in the morning and late in the evening.

For Winter

– Ensure you have adequate heating, as Portuguese houses are often poorly insulated. – Use dehumidifiers to combat excessive humidity. – Invest in blankets and warm clothing for cool evenings.

Year-Round

– Choose natural, breathable materials for your bedding and clothing. – Create shaded outdoor spaces to enjoy the outdoors without direct heat. – Consider installing window screens to enjoy fresh air without insects.

Gearing Up for the Seasons

Although the Portuguese climate is generally mild, it’s important to equip yourself properly for each season:

Summer

• Light, breathable clothing in natural fibers
• Wide-brimmed hats and sunglasses
• High-SPF sunscreens
• Insulated water bottle to keep water cool

Winter

• Warm, waterproof clothing for rainy days
• Waterproof shoes
• Quality umbrella
• Moisturizing creams to combat skin dryness from heating

Shoulder Seasons

• Adaptable layered clothing to adjust to temperature variations
• Light scarves for wind protection
• Antihistamines for seasonal allergies (with medical advice)

Preventing Climate-Related Illnesses

Although Portugal is a safe country health-wise, certain climate-related precautions should be taken:

Mosquito Protection: Use repellents and mosquito nets, especially in humid regions and during hot months.

Hydration and Nutrition: Maintain good food hygiene, especially in summer, to avoid food poisoning.

Skin Monitoring: Have your skin regularly examined by a dermatologist, as prolonged sun exposure increases the risk of skin problems.

Adapted Physical Activity: Listen to your body and adjust your physical activity level, especially during the acclimatization period.
