Loudest neighborhoods near Lisbon: Olivais (Santa Maria dos Olivais), Alvalade, Campo Grande, Areeiro. Quietest: Bairro Alto / Chiado, Príncipe Real, Belém, Cais do Sodré / Alfama. Busiest around 1 PM local time averaging 712 flights/day. Source: Flight Path Noise monitoring data, 30 days to 2026-10-27.
Does Lisbon Airport have a curfew?
Yes — a mandatory night curfew, 1 AM – 5 AM.
since 2023 there’s an official 1 AM to 5 AM ban on flights at LIS. Enforcement has been inconsistent (the regulator handed out roughly €2 million in fines in six months for violations), but a tougher curfew is being phased in. Until then, expect occasional late-night flights despite the formal ban.
Lisbon is unusual for a major European capital: its main airport sits inside the city limits, with its runway extending into the heart of residential Lisbon. Roughly 57,000 residents live in zones exceeding EU noise limits. Protests, fines for airline noise violations, and a slow-moving plan to relocate the airport to Alcochete (40 km east) are all live issues. This page combines a live ADS-B map of every flight passing LIS with notes on which neighborhoods catch the runway and which are clear.
Which neighborhoods are quietest — and which aren’t
LIS has one runway, 02/20 (running roughly north-east to south-west). The flight path bisects the northern half of Lisbon — Olivais sits directly under the runway, with Alvalade, Campo Grande, and Areeiro on the corridor as it extends south-west across the city.
If you’re moving to Lisbon and care about aircraft noise, the practical move is anywhere south or west of Avenida da República — Bairro Alto, Chiado, Príncipe Real, Cais do Sodré, Alfama, and Belém are all comfortably off the corridor. Olivais and western Alvalade are the worst-affected; if you’re looking at apartments there, drop a pin on the map above to check before signing.
| Area | Noise | Why |
|---|---|---|
| Olivais | ✈︎✈︎✈︎ | Immediately south of the runway; centre of the noise debate |
| Alvalade (western) | ✈︎✈︎✈︎ | Directly under the corridor; loudest residential pocket |
| Campo Grande | ✈︎✈︎✈︎ | Under wide approach + departure corridor |
| Areeiro | ✈︎✈︎✈︎ | 3–4 km south of runway; in noise-affected zone |
| Avenidas Novas | ✈︎✈︎ | Edge of corridor; less intense |
| Bairro Alto / Chiado | ✈︎ | South-west of corridor; nightlife noise the bigger issue |
| Príncipe Real | ✈︎ | Off corridor, mostly aircraft at altitude |
| Belém | ✈︎ | 12 km west, well clear |
| Cais do Sodré / Alfama | ✈︎ | Riverside, off the corridor |
Flight patterns and runway use
LIS uses a single runway, 02/20 (running NE-SW across the airport; renumbered for magnetic drift in May 2022 — the old cross-runway is closed). The default configuration is runway 20 — takeoffs head south-west across Alvalade and Areeiro toward the Tagus, arrivals come in from the south-west passing over the same corridor. When the wind shifts to 02 operations, takeoffs head north-east toward the Vale do Tejo suburbs, arrivals come in from the north over Loures.
The route-density layer above shows the cumulative pattern: the bright corridor sweeps across northern Lisbon from south-west to north-east, fading rapidly outside that swathe. Western Lisbon (Bairro Alto, Belém) and the south-bank side of the Tagus are mostly clear.
When is it quietest?
Officially LIS observes a 1 AM to 5 AM night-flight ban (since 2023). Enforcement has been inconsistent — the aviation regulator issued ~€2 million in fines in just six months for airlines breaking the curfew — but the rule is being tightened. Quiet hours in practice: roughly 1–5 AM with occasional late or early flights; peak hours mid-morning and early evening.
For a specific address, drop a pin on the map above to see the hourly profile. Addresses in Olivais or Alvalade will show a clear daytime peak with audible early-morning traffic; addresses in Bairro Alto or Chiado will show flat profiles dominated by ground noise.
How to check noise at your specific address
The map above is the answer to “is this spot loud?” Three steps:
- Search your address or postcode in the bar at the bottom of the map.
- Drop a pin — click the location marker that appears.
- Read the noise report that opens in a panel below the map: average daily noise (Leq), peak observed dB, flights per day passing within 2 km, and an hourly breakdown showing exactly when those flights happen.
The Noise Heatmap layer (orange/red = louder) and the Route Density layer (purple/magenta = busier flight corridors) make the sweep across northern Lisbon obvious — a bright band that’s hard to miss. Most southern and western Lisbon addresses will land in the green/quiet zone.
Frequently asked questions
- Which Lisbon neighborhoods are affected by aircraft noise?
- Olivais, Alvalade (especially the western half), Campo Grande, and Areeiro all sit directly under the LIS flight path and are part of the official noise-affected zones. Roughly 57,000 Lisbon residents are estimated to live in zones exceeding EU noise limits.
- Which Lisbon neighborhoods are quietest for aircraft noise?
- Bairro Alto, Chiado, Príncipe Real, Cais do Sodré, Alfama, and Belém all sit south-west of the corridor and well off the main flight paths. They're the practical default for nomads who want central Lisbon without the airport on top of them.
- Is Bairro Alto noisy from planes?
- Bairro Alto is loud — but mainly from nightlife, not aircraft. The neighborhood sits south-west of the LIS corridor, so flights are mostly at altitude or off-centerline overhead. Light sleepers will have a harder time with the bars and tram noise than with the airport.
- Is Lisbon's airport closing?
- Eventually. A new airport (Aeroporto Luís de Camões) is planned at Alcochete, 40 km east of the city. Operational date is officially 2034 but internal estimates lean toward 2037 or later. Until then LIS continues to operate inside the city with substantial residential impact.
- Should I avoid Olivais and Alvalade?
- If aircraft noise is a primary concern, yes. Olivais and western Alvalade are the most consistently affected; Areeiro and Campo Grande are not far behind. Property prices in these zones reflect the noise impact — research consistently shows a measurable per-decibel discount in the affected corridor.
- How does Lisbon aircraft noise compare to other European capitals?
- Lisbon is unusually severe for a European city — a major hub airport sitting *inside* the city limits is rare in Europe (Paris, Madrid, Barcelona all moved their major airports out decades ago). The 1 AM curfew helps, but daytime exposure in Olivais and Alvalade is among the worst in any major European residential district.
- Does aircraft noise affect Lisbon property values?
- Yes, significantly in the affected zones. Research on aircraft noise consistently shows a 0.5–1.0% house-price reduction per decibel of exposure. Properties in Olivais and western Alvalade trade at a measurable discount versus comparable properties in Bairro Alto, Chiado, or further west.
