When to Cycle in Portugal?

Portugal is a year-round cycling destination, blessed with a mild climate, diverse landscapes, and more than 300 days of sunshine in some regions. 

In general there’s always somewhere in Portugal with great conditions for biking. 

In fact, it's often called Europe’s favourite winter cycling destination, thanks to the warm, dry weather in the Algarve and Madeira while much of the continent is still under rain or snow.

That said, the best time to cycle in Portugal depends on where you're headed and what kind of ride you’re after. 

In this guide, you’ll find everything you need to know about Portugal’s climate, including a month-by-month breakdown and detailed tips for riding in each of the country’s top cycling regions.

Going on a cycling tour in Portugal is one of the most rewarding ways to explore the country’s diverse landscapes, rich culture, and warm climate. But with coastal winds, inland heat, and island microclimates, timing your trip can make all the difference.

In this guide, we break down when and where to go cycling in Portugal, with pro tips on riding conditions across the top cycling regions in Portugal—from the Douro Valley and the Algarve to Madeira and the Azores.

Understanding the Rainfall Patterns

Portugal’s rainfall is far from uniform. Here's what's important to know when planning your cycling tour:

• The north is significantly wetter than the south due to the Atlantic’s influence.
• Porto can receive 180+ mm of rain in November and December — that’s 6 times more than summer!
• Lisbon sees moderate rain in winter but has much drier summers.
• Faro, in the southern Algarve, stays mostly dry year-round, with just 20–30 mm of rain in winter months.

What About the Heat?

Rain might make you cautious, but heat is what really tests your limits on a bike:

• Lisbon has a classic Mediterranean climate: Warm springs, hot and dry summers — highs often reach 29°C (84°F) in August.
• Porto stays milder year-round, even in summer: Highs around 25°C (77°F) in July/August, with cooler, damper winters.
• Faro, in the Algarve, enjoys the warmest year-round climate: Summers easily hit 30°C+ (86°F+), but winters stay mild, averaging 16°C (61°F).
• Inland areas like Évora and Beja (not shown in the chart) get hotter still, often 35–40°C (95–104°F) in midsummer.

It Can Get Windy!

While rain and heat get all the attention, wind can make or break a ride, especially when cycling on open coastal or inland roads. Portugal is generally a windy country, with patterns shaped by the Atlantic Ocean, coastal geography, and seasonal shifts.

• Windiest months: February and March often bring the strongest gusts, especially in the north and along the Atlantic coast.
• Calmest months: September tends to be more stable, with light, steady breezes that are great for riding.
• Northern Portugal sees higher average wind speeds year-round — up to 18 km/h (5 m/s) in winter.
• Lisbon varies by location: exposed areas like Gago Coutinho can be breezy, while sheltered valleys stay calmer.
