Best Time to Visit Lisbon
The best month to visit Lisbon is May. You get the ideal balance of warm temperatures, manageable crowds, and lower flight prices before the summer rush. The city is in bloom, the outdoor kiosks (quiosques) are active, and you avoid the intense heat waves of July and August.
If you prefer a party atmosphere, June is the runner-up for the street festivals. If you are on a strict budget, January offers the deepest discounts on high-end hotels. However, for the classic Lisbon experience—walking the seven hills without overheating or getting stuck in rain—May is the window.
Month by Month in Lisbon
Lisbon in January
January is the coldest month. Temperatures sit between 8°C (46°F) and 15°C (59°F). It is often rainy, but when the sun shines, the light is exceptionally clear for photography. Crowds are at their lowest point of the year. You will find the cheapest hotel rates this month. Visit the El Corte Inglés sales for steep retail discounts or warm up with a coffee at a historic café in Chiado.
Lisbon in February
Weather remains cool and unpredictable, ranging from 9°C to 16°C (48°F–61°F). Rainfall is common but usually comes in short bursts. February is all about Carnival. While the biggest parades are in nearby Torres Vedras, Lisbon hosts neighborhood street parties and themed events. It is a quiet time for sightseeing, meaning no lines at the Jerónimos Monastery. Prices stay low until the end of the month.
Lisbon in March
Spring begins to show. Temperatures rise to a comfortable 10°C to 19°C (50°F–66°F). You will see more sunny days, though a light jacket is still necessary. The city starts feeling lively again. March marks the start of the Lisbon Half Marathon, one of the fastest courses in the world. It is the last month to snag "off-season" prices before the Easter surge.
Lisbon in April
April in Lisbon is the transition month. Expect temperatures between 12°C and 20°C (54°F–68°F). The weather can be "unsettled," so pack an umbrella. Despite the potential for rain, the city becomes lush and green. April 25th is Liberty Day, a major national holiday celebrating the Carnation Revolution with parades and concerts along Avenida da Liberdade. Tourist numbers begin to climb steadily.
Lisbon in May
May is peak Lisbon. Temperatures hover between 14°C and 23°C (57°F–73°F). It is warm enough for t-shirts but cool enough for long walks in Alfama. The jacaranda trees bloom, turning the city streets purple. Prices are moderate—higher than winter, but lower than summer. Spend your afternoons at a rooftop bar like Park or Lumi without the suffocating crowds of July.
Lisbon in June
June is the month of Santos Populares. Temperatures range from 16°C to 26°C (61°F–79°F). The city smells like grilled sardines. June 12th and 13th are the peak, celebrating St. Anthony with massive street parties, parades, and outdoor dancing. Expect high prices and packed streets. If you don’t like noise and crowds, avoid the city center during the second week of June.
Lisbon in July
Summer is in full swing. Temperatures consistently hit 18°C to 28°C (64°F–82°F), with occasional heat waves pushing past 30°C. It is dry and windy, particularly in the evenings. This is the best time to take the train to Cascais or Estoril for the beaches. High season means peak prices for flights and accommodation. Book your dinners and museum tickets well in advance.
Lisbon in August
August is hot and crowded with international tourists, while many locals leave for the Algarve. Temps range from 19°C up to 30°C (66°F–86°F). Some independent shops and family-run tascas may close for staff holidays. It is the prime month for outdoor music festivals like Jazz em Agosto at the Gulbenkian Foundation. Atmospheric "Nights at the Museum" events often take place during this time.
Lisbon in September
September is the "secret" high season. The extreme heat fades, leaving temperatures between 17°C and 27°C (63°F–81°F). The ocean is at its warmest, making it the best month for surfing in nearby Peniche or Ericeira. Crowds thin out slightly compared to August, but hotel rates remain high. It is an excellent time for a day trip to the palaces of Sintra.
Lisbon in October
October is pleasantly mild with temperatures of 15°C to 23°C (59°F–73°F). The first half of the month often feels like an extended summer, known locally as Veranico de São Martinho. Rainfall increases toward the end of the month. Prices start to dip, making mid-range luxury hotels more accessible. Check out Doclisboa, the city’s premier international documentary film festival held every October.
Lisbon in November
November brings the rain and cooler air, with temperatures between 11°C and 18°C (52°F–64°F). It is damp but rarely freezing. This is the best time for foodies. The smell of roasting chestnuts fills the air from street vendors (magustos). It is also the month of the Web Summit, which brings thousands of tech professionals to the city, causing a temporary spike in hotel prices.
Lisbon in December
December is festive and cool, ranging from 9°C to 15°C (48°F–59°F). Lisbon does not get as cold as Northern Europe, making it a popular winter escape. The city lights are spectacular, especially in Baixa and Chiado. Visit the Wonderland Lisboa Christmas market in Eduardo VII Park. While it rains frequently, the cozy Fado houses in Mouraria provide the perfect refuge.
Cheapest Time to Visit Lisbon
The cheapest time to visit Lisbon is from January to early March.
Post-holiday demand drops significantly in the second week of January. You can find four-star hotels for under €100 per night and flight deals from major European hubs for less than the cost of a taxi.
- Accommodation: Check prices in the Avenida da Liberdade district; luxury hotels often slash rates by 40-50% compared to June.
- Dining: Lunch specials (prato do dia) remain consistent year-round, but you will find it easier to get tables at high-end restaurants without booking weeks ahead.
- Airlines: TAP Air Portugal and low-cost carriers like Ryanair and EasyJet have their lowest fares during this window.
Avoid the week of the Web Summit in November. Even though it is technically "off-season," 70,000+ attendees flood the city, tripling hotel rates and filling every Airbnb.
When to Avoid Lisbon
Avoid Lisbon in August if you hate crowds and heat. The city becomes an oven, and the narrow streets of Alfama and Bairro Alto are overwhelmed by cruise ship passengers and tour groups. Many authentic, locally-owned spots close for their own vacations, leaving you with the "tourist trap" versions.
You should also avoid the second week of June if you value sleep. The Festas de Lisboa involve loud music and street parties that last until 4:00 AM. If your hotel is in a central neighborhood like Graça or Bica, you will not get any rest. However, if you are there to party, this is actually the best time to go.
Best Time for Good Weather
For the most reliable "blue sky" days without oppressive heat, visit between May and June or September and October.
Lisbon has a Mediterranean climate but is heavily influenced by the Atlantic. This means summer heat is often tempered by a breeze (the Nortada), but it also means winter can be deceptively damp.
- Sun Seekers: July and August offer 11+ hours of sunshine a day and almost zero chance of rain.
- Active Travelers: March to May offers highs of 18°C–22°C, which is the limit for comfortable hiking or heavy walking.
- Beach Goers: September is the winner. The air is still warm, the wind dies down, and the Atlantic water temperature is at its annual peak (around 20°C).
Best Time for Fewer Crowds
To have the city to yourself, aim for mid-January to February or November.
Lisbon is now a top-tier global destination; there is no longer a time when it is truly "empty." However, the shoulder seasons offer a reprieve:
- Late October/Early November: After the summer tourists leave and before the Christmas shoppers arrive. Most attractions have zero wait times.
- Weekdays in March: Schools are in session and the spring break crowd hasn't arrived.
- Tuesdays and Wednesdays: Regardless of the month, mid-week is always significantly quieter than the Friday-Sunday weekend tripper peak.
If you visit during a busy month, get to the Belém Tower or Sintra by 9:00 AM. By 11:00 AM, the crowds are unmanageable regardless of the season.
