April is a transitional month in Portugal, bridging the cooler, wetter winter months and the sunny, dry days of summer. It’s a time when the weather becomes increasingly favorable, with warmer days, longer daylight hours, and landscapes that come alive with color.

In contrast, southern Portugal and the islands of Madeira and the Azores often enjoy sunnier, drier conditions. Whether you’re a foodie, a history buff, or an outdoor enthusiast, April is an ideal month to experience the best of Portugal without the peak-season crowds.

Rainfall and Precipitation Patterns
Rainfall in April continues to decrease across Portugal, with the northern and central regions experiencing more rain than the south.

The Algarve, being the driest region, records just 20-40 mm of rain across 4 to 6 days.
Rain showers are typically short-lived, often followed by sunshine. This makes it easy to plan outdoor activities, provided you carry a light raincoat or umbrella for unexpected downpours.
Sunshine Hours and Daylight in April
April brings longer days and more sunshine to Portugal, with daylight hours increasing to 11–13 hours by the end of the month. Sunshine levels vary by region:
- Lisbon: 6–7 hours of sunshine daily.
- Porto: 5–6 hours of sunshine daily.
- Algarve: 8–9 hours of sunshine daily.

Wind and Ocean Conditions in April
The Atlantic Ocean plays a significant role in Portugal’s coastal weather, and April is no exception. Coastal regions experience gentle breezes, with average wind speeds ranging between 10 and 18 km/h (6 to 11 mph). These winds are typically mild but can feel brisk along the northern and central coasts, especially during the evenings.
The ocean temperature in April averages around 15°C (59°F) in northern regions like Porto and around 16°C (61°F) to 18°C (64°F) in the Algarve and Madeira. While these temperatures may still be chilly for swimming without a wetsuit, they’re perfect for water sports enthusiasts, including surfers and paddleboarders. The Algarve’s calmer seas are particularly inviting for kayaking and coastal boat tours.
In the Azores, ocean conditions remain slightly cooler, with temperatures around 16°C (61°F). The islands’ strong connection to the Atlantic also means occasional rough seas, which can disrupt ferry schedules or water-based tours. Travelers are advised to check local conditions when planning ocean activities.
Seasonal Changes: Spring in Full Bloom
The countryside is awash with wildflowers, including poppies, lavender, and daisies, creating picturesque landscapes perfect for photography and nature walks.
Almond trees continue to bloom in the Algarve, while vineyards in the Douro Valley begin to show the first signs of life after winter dormancy. In Madeira, the island’s lush vegetation and vibrant gardens, like the Monte Palace Tropical Garden, are at their peak during April.
Wildlife activity also increases in spring. Birdwatching enthusiasts can spot migratory species returning to Portugal’s wetlands, including the Ria Formosa Natural Park in the Algarve and the Tagus Estuary near Lisbon. Whale and dolphin watching tours in the Azores also pick up in popularity during this month, as marine life becomes more active in the warming waters.
Activities Perfect for April Weather
Portugal’s hiking trails are a highlight in April, offering stunning views without the summer heat. In the Algarve, the Seven Hanging Valleys Trail provides breathtaking coastal vistas, while the Rota Vicentina offers a more rugged, off-the-beaten-path experience. Madeira’s levada walks remain a top attraction, leading visitors through forests, mountains, and waterfalls.
Cycling is another popular activity, particularly in the Alentejo, where quiet roads wind through rolling hills and vineyards. For those who prefer a more relaxed pace, a leisurely stroll along Portugal’s beaches, especially in the Algarve or on Madeira’s shores, is equally rewarding.
Wander through Lisbon’s Alfama district, visit the ornate Jerónimos Monastery, or enjoy the views from São Jorge Castle. In Porto, the Ribeira district and the iconic Dom Luís I Bridge offer plenty of photo opportunities. Sintra, with its fairytale-like palaces and gardens, is especially enchanting during this time of year.
Portugal hosts several festivals and events in April, offering unique cultural experiences. Easter celebrations, if they fall in April, are a significant occasion throughout the country, with processions, feasts, and traditional music. Madeira’s Flower Festival, held in late April or early May, is a spectacular event that showcases the island’s stunning floral beauty with parades and displays.
Packing Essentials for April
Packing for Portugal in April requires a mix of clothing and accessories to accommodate the changing weather:
- Bring lightweight tops, sweaters, and a jacket for cooler evenings.
- A compact umbrella or raincoat is useful, especially for northern and central regions.
- Opt for sturdy, weather-appropriate footwear for walking and hiking.
April marks a noticeable improvement in weather compared to March, with warmer days, reduced rainfall, and more sunshine.
