Spring 2026: when and where to see the jacaranda bloom in Lisbon

Lisbon planted its first jacaranda trees in the early 20th century, imported from Mozambique via the botanical gardens, and the city has been adding them since. There are now thousands of them, lining avenues and filling squares from April through May with flowers that are exactly between purple and blue — a colour that has no precise English name, which seems right for something this specific.

In 2026, the bloom in Lisbon was earlier than average. By April 20th the Avenida Almirante Reis had its canopy up. By April 30th — the date of this post — the Largo do Intendente and Avenida da República were at peak.

When the bloom happens

The jacaranda season in Lisbon is weather-dependent and therefore variable by a few weeks, but the typical pattern:

Late April: First trees in sheltered, warmer spots (Intendente, lower Alfama) begin to flower
Early-to-mid May: Peak bloom across most of the city, including the main avenues and university district
Late May to early June: The flowers fall — spectacular in their own right, carpeting pavements in purple-blue

In 2026, the warm April (several days above 22 degrees by mid-month) pushed the bloom forward by about 10 days compared to 2025.

Where to see them

Avenida Dom Carlos I (Santos area): A long, straight avenue lined with mature jacarandas that forms a tunnel of purple canopy at peak bloom. One of the best in the city. Easy to reach from Cais do Sodré on foot (15 minutes).

Avenida Almirante Reis: The longest avenue in central Lisbon, running north from Martim Moniz through Intendente and Arroios. The jacarandas here are particularly mature and large-canopied. The contrast with the colourful azulejo building facades is the thing photographs are made of.

Largo do Intendente: The square has four or five large jacarandas that, at peak bloom, provide a purple canopy over the entire space. The late afternoon light (16:00-18:00) is particularly good here when the sun comes from the west and illuminates the flowers.

Universidade Nova (Campo Mártires da Pátria): The university precinct has a significant concentration and is slightly less trafficked than the main avenues.

Sintra: The jacarandas in the Sintra hills bloom slightly later than Lisbon (cooler altitude) and are scattered through the town and palace gardens. The combination of jacaranda flowers and Pena Palace in May is unreasonably beautiful.

The 2026 specific notes

By late April 2026, the bloom was notably good — dense flowers on trees that had a wet winter and a warm spring, which is the combination that produces the best displays. The Avenida Dom Carlos I is at or near peak as of April 30th. The Avenida Almirante Reis will be at peak by May 5-8 based on current progress.

The flowers fall from mid-May onward. If you’re visiting in the second half of May, the purple carpet on the pavement is its own aesthetic reward, though less dramatic than the tree-canopy version.

Spring as a travel season

The jacaranda season overlaps with what is, broadly, the best season to visit Lisbon:

Temperature: 17-22 degrees Celsius in April-May. Warm enough for outdoor dining and viewpoint-sitting; not the exhausting heat of July.
Crowds: Significant but not at July-August levels. Sintra is busy but manageable with the right timing; most Lisbon attractions don’t have the extreme midday queues of high summer.
Prices: Mid-range. Lower than July-August peak; higher than November-February off-season.
Rainfall: April in particular can be showery. May is more reliable. The pattern tends toward morning cloud clearing to afternoon sun.

What else is happening in spring 2026

NOS Primavera Sound (June): The major alternative music festival traditionally held in Porto in June has had some Lisbon extension events. Check the programme for 2026.

Festas de Lisboa (all of June): Heading toward the Santo António festivals on June 12-13 — the neighbourhood parties, the sardines, the marchas populares parade. The festas season is building through late May.

Sintra spring light: The Serra de Sintra in May, when the moisture from the Atlantic keeps the vegetation unusually green and the palace gardens are in full bloom, is at its most beautiful. The Sintra day trip guide covers how to do it right.
