When Do the Clocks Change in Portugal in 2026?
Portugal's clocks spring forward on Sunday, March 29, 2026, at 1:00 AM Western European Time (WET). At that moment, clocks jump to 2:00 AM Western European Summer Time (WEST). You lose one hour of sleep — and gain an extra hour of evening daylight.
This is the same date that all EU member states change their clocks (the last Sunday in March). Portugal is not technically an EU holdout on timekeeping: it harmonized with the EU DST schedule in 1996.
The autumn change — when clocks fall back — takes place on Sunday, October 25, 2026, at 2:00 AM WEST, reverting to 1:00 AM WET (UTC+0).
What Do WET and WEST Mean?
Portugal (mainland) observes two time zones throughout the year:
- WET — Western European Time (UTC+0): Portugal's standard time, October through late March. Same as GMT/UTC. This means Lisbon is, unusually, in the same time zone as London during winter — despite being geographically further west.
- WEST — Western European Summer Time (UTC+1): Portugal's summer time, late March through October. Clocks are one hour ahead of UTC, placing Lisbon one hour ahead of London (which is also at UTC+1 during BST, so they align again in summer).
Portugal's choice to use WET rather than a more "western" offset is a historical quirk. Geographically, Portugal sits on the western fringe of Europe and many solar noon calculations would suggest UTC-1 is more natural. But Portugal aligned with Central Europe for trade and convenience, and has been at UTC+0 (WET) in winter since the 1970s.
Portugal Mainland vs. Azores vs. Madeira
The clock change story differs across Portugal's three regions:
| Region | Standard Time | Summer Time | Spring Change (2026) | Autumn Change (2026) |
|---|---|---|---|---|
| Mainland Portugal + Madeira | WET (UTC+0) | WEST (UTC+1) | Mar 29 at 1:00 AM | Oct 25 at 2:00 AM |
| Azores | AZOT (UTC−1) | AZOST (UTC+0) | Mar 29 at 0:00 AM | Oct 25 at 1:00 AM |
The Azores are one hour behind mainland Portugal year-round. This makes them unique in Europe — they are the only part of the EU that uses a UTC−1 offset in winter. During summer the Azores shift to UTC+0, which means they are briefly in the same timezone as mainland Portugal only in the sense that both have moved forward: Azores to UTC+0 and mainland to UTC+1.
Madeira follows mainland Portugal exactly: WET in winter, WEST in summer, changing on the same dates.
Why Does Portugal Observe Daylight Saving Time?
Portugal, like all EU member states, is required by EU Directive 2000/84/EC to observe seasonal clock changes on harmonized dates. The last Sunday in March and last Sunday in October are fixed across all EU countries.
This hasn't been without controversy. Portugal briefly experimented with Central European Time (CET, UTC+1) in the late 1960s for alignment with Spain and the rest of Europe, but the resulting very late sunrises in winter — some mornings not until after 9 AM — were deeply unpopular and the country reverted to WET by 1976.
The EU Parliament voted in 2019 to abolish seasonal clock changes by 2021, allowing each member state to pick permanent summer or winter time. The proposal has stalled in the Council and as of 2026 has not been implemented. Portugal continues to change clocks twice a year.
Impact on Travel and Scheduling
The March 29 clock change has a few practical implications for travel between Portugal and other countries:
- Portugal and the UK both change on March 29 — so the time difference between Lisbon and London stays the same (zero hours in winter, zero hours in summer under WEST/BST respectively). No disruption for UK–Portugal travelers.
- Portugal and Spain — Spain uses CET/CEST (UTC+1/UTC+2). After March 29, Spain is still one hour ahead of mainland Portugal (UTC+2 vs. UTC+1). This gap is constant year-round.
- Portugal and the US East Coast — The US changed its clocks on March 8, 2026 (three weeks earlier). For those three weeks, Portugal (WET, UTC+0) was five hours ahead of New York (EDT, UTC−4). After March 29, Portugal shifts to WEST (UTC+1), making it five hours ahead again. The gap briefly changed and then stabilized — watch out for this if you scheduled calls between those dates.
- Portugal and Brazil — Brazil abolished DST in 2019 and stays on BRT (UTC−3) year-round. After March 29, the gap between Lisbon and São Paulo grows from 3 hours (WET vs. BRT) to 4 hours (WEST vs. BRT).
When Will Portugal's Clocks Change Next?
Looking ahead at Portugal's remaining clock changes:
- Fall back 2026: Sunday, October 25, 2026 at 2:00 AM WEST → 1:00 AM WET
- Spring forward 2027: Sunday, March 28, 2027 at 1:00 AM WET → 2:00 AM WEST
- Fall back 2027: Sunday, October 31, 2027 at 2:00 AM WEST → 1:00 AM WET
Frequently Asked Questions
What time do clocks change in Portugal in 2026?
Portugal clocks spring forward on Sunday, March 29, 2026, at 1:00 AM WET (Western European Time). Clocks move to 2:00 AM WEST. In autumn, clocks fall back on Sunday, October 25, 2026, at 2:00 AM WEST, reverting to 1:00 AM WET.
What is Portugal's time zone after the clock change?
After the March 29 spring change, mainland Portugal and Madeira move to WEST (Western European Summer Time, UTC+1). The Azores shift to AZOST (UTC+0). Portugal stays in these summer time zones until the October 25 autumn change.
Does Portugal use daylight saving time?
Yes. As an EU member state, Portugal observes daylight saving time on the EU's harmonized schedule: clocks spring forward on the last Sunday of March and fall back on the last Sunday of October.
Is the Azores time change the same date as mainland Portugal?
The Azores change on the same calendar date (March 29, 2026) but at a different clock time — midnight local time (0:00 AM AZOT) rather than 1:00 AM. Since the Azores are one hour behind mainland Portugal, the transitions are simultaneous in UTC terms.
Will Portugal abolish daylight saving time?
The EU voted in 2019 to let member states choose permanent time, but the directive has not been implemented as of 2026. Portugal continues to observe DST. There has been public discussion in Portugal about choosing permanent WEST (staying on UTC+1 year-round), but no legislation has passed.
What time is Portugal in summer vs. winter?
In winter (October to late March), mainland Portugal is on WET (UTC+0) — the same as GMT/London. In summer (late March to October), it moves to WEST (UTC+1) — the same as BST. Lisbon is therefore aligned with London in both seasons, despite being further west geographically.
What is DST Portugal 2026 start date?
Daylight saving time in Portugal starts on Sunday, March 29, 2026. Clocks move forward one hour at 1:00 AM local time.
