Spain's national holiday could change supermarket hours. Mercadona is generally expected to close, while selected convenience stores may open with reduced hours. Each branch requires a direct check.
Branch-level rules will decide whether shoppers can buy essentials across Spain on Sunday 11 October and Monday 12 October 2026.
The available research does not independently confirm a nationwide timetable for Mercadona on either date. Lidl, Carrefour, DIA and Alcampo are also expected to follow local schedules, with the store format and regional rules carrying more weight than the chain name.
Sunday 11 October will largely follow habitual weekend opening rules. Monday 12 October is more restrictive because Día de la Hispanidad is generally treated as a national holiday. The specific 2026 holiday status was not independently confirmed in the available BOE results, and local retail calendars may affect opening permissions.
The Lidl pages found in the research confirm that products are available from 12 October, but they do not provide an official opening timetable for particular branches on the holiday.
For a last-minute shop, the safest assumption is that branches will not share one timetable. Several chains leave the final decision to the store type, local regulations or the area where the premises are located.
Mercadona closes on both days
Mercadona keeps its established policy of closing on Sundays and public holidays. The available research did not include an official Mercadona notice confirming that all supermarkets will remain closed across Spain on Sunday 11 October and Monday 12 October. Customers should verify the relevant branch and regional calendar before relying on that assumption.
The available materials contain no official timetable for Mercadona, Carrefour, DIA or Alcampo for these dates. They also do not independently verify the specific claim that Mercadona will close nationwide on both days, which is why branch-level checking remains essential.
There is no reduced timetable to rely on with this chain unless an individual store or regional notice says otherwise. Customers who normally use Mercadona should finish their shopping before the two dates or switch to another retailer authorised to open, after checking the local information.
Lidl keeps a narrower holiday offer
Lidl stores that normally open at weekends may operate on Sunday 11 October 2026 under their usual local schedule. The previously cited ranges of 09:00 to 21:30 or 22:00 in some urban areas and tourist destinations are indicative only. They are not a confirmed timetable for every branch.
The picture changes on Monday. Much of the Lidl network may close for the national holiday, although selected branches in large cities could open with special or reduced hours. Authorised commercial areas or tourist enclaves may also have exceptions. The chain's official online store finder is the relevant check before travelling, because the Lidl pages found in the research do not confirm which branches will open on 12 October.
Carrefour separates large stores from proximity shops
Carrefour hypermarkets and supermarkets that habitually open on Sundays may do so on 11 October. Carrefour Market and Carrefour Express locations that normally operate that day may follow the same pattern. That gives Carrefour a potentially broader Sunday option than Mercadona, but only where the individual branch already opens at weekends. No official Carrefour schedule for these dates was included in the available research.
On Monday 12 October, large surfaces and hypermarkets may remain closed. Carrefour Express and some Carrefour Market stores could instead open on a special or reduced holiday schedule. Previously cited patterns range from 09:00 or 10:00 until 15:00 to continuous evening opening. Those times are not independently confirmed for particular premises and must be checked locally.
DIA leaves the widest local variation
DIA's Sunday timetable will depend on each shop's usual opening pattern and the rules applied in its autonomous community. Some locations may open while others remain closed, but the available materials do not provide an official branch-by-branch timetable.
Monday is equally branch-specific. DIA has many proximity stores and operates through a franchise model, so individual shops may use a holiday schedule such as 09:00 to 14:30. Others may use reduced or continuous hours extending to the evening, including 09:00 to 21:30, while some will close altogether. These examples are planning scenarios rather than verified hours for 12 October 2026.
Alcampo limits the holiday opening
Most Alcampo hypermarkets located in large shopping areas may close on Monday 12 October. Exceptions are expected among proximity and convenience formats such as Mi Alcampo. Centres in commercial areas authorised to open on the holiday may also operate, but no official Alcampo schedule was present in the research materials.
The store format matters as much as the brand. One chain can combine closed hypermarkets with open neighbourhood shops, while Sunday availability does not guarantee Monday availability.
An earlier Euskadi report concerned a hospital case rather than retail opening hours. The operational point here is narrower: the branch and its local trading rules must be checked before travelling.
These schedules do not provide a verified national timetable. Mercadona is generally expected to offer no holiday option on either date. Lidl and Carrefour may provide limited Monday possibilities through selected locations. DIA has substantial franchise-level variation. Alcampo may concentrate exceptions in convenience shops and authorised areas. The retailer's official locator and the relevant regional trading calendar remain the checks for any Monday opening.
