August in Madrid is not the month the city closes; it is the month a handful of seasonal calendars change. On AEMET normals for the Madrid-Retiro observatory it is the driest month of the year, with 10 mm of rain and 1.7 rain days, and among the hottest, at 31.3 degrees average high on a mean of 25.1. The municipal pools are mid-season and several museums run later, with the Museum of Romanticism open to 8.30pm and the Cerralbo still shutting at 3pm.
What is open in Madrid in August? The city does not close. Specific calendars change: the municipal pools run 15 May to 6 September, the Museum of Romanticism stays open to 8.30pm and free until 31 August, and the Cerralbo still shuts at 3pm. It is the driest month, at 10 mm.
August in Madrid combines two conditions that reinforce each other: the peak of heat and the year’s minimum rainfall. That pushes plans indoors and towards water, and there what decides is not whether something is open but what time it closes, because summer and winter timetables do not match even inside one group of museums.
How to build an August day
The structure that works is the reverse of the one for a mild month.
Indoors through the middle hours, taking advantage of the museums that close late, and streets at the end of the afternoon. Lunch does not begin until about 2pm and dinner until 9pm, in where to eat in Madrid, so the hottest stretch of the day lands exactly on lunch. The indoor list is in Madrid on a rainy day, which works just as well against heat.
The driest month, and one of the hottest
The figures explain why an August plan is organised the opposite way round to an October one.
| August figure | Value |
|---|---|
| Clear days | 13.6 |
| Rain days | 1.7 |
| Rainfall | 10 mm |
| Mean temperature | 25.1 degrees |
| Average high | 31.3 degrees |
Against October, the wettest month at 60 mm, August takes six times less water. The full year is in the best time to visit Madrid.
What opens because it is August
Some calendars exist only in summer, and this month falls squarely inside them.
The municipal summer pools run 15 May to 6 September across 25 open-air sites, in fixed sessions at 2.25 € for an adult, in Madrid’s summer pools. The region’s five monitored bathing spots run 15 May to 15 September, in where you can swim in the Madrid region.
The museums that stretch, and the one that does not
Inside a single 3 € tariff there are more than five hours of difference in closing time, and August makes it obvious.
The Museum of Romanticism keeps summer hours to 8.30pm Tuesday to Saturday and applies free access until 31 August 2026, in Museum of Romanticism tickets. The National Archaeological Museum closes at 8pm all year, in Archaeological Museum hours. The Cerralbo still shuts at 3pm except on Thursdays, in Cerralbo Museum hours.
At 31.3 degrees average high it pays to know where to refill, and the city has 2,268 working drinking fountains, spread from 228 in Moncloa-Aravaca down to 40 in Chamberí.
Frequently asked questions about Madrid in August
Does Madrid shut down in August?
The city does not close, though the pace drops. What changes are specific seasonal calendars, such as the municipal summer pools, the extended hours some museums keep, and free-entry windows that end on 31 August.
How hot is Madrid in August?
The average high is 31.3 degrees on a mean of 25.1, according to AEMET normals for the Madrid-Retiro observatory. In exchange it is the driest month of the year, with 10 mm of rainfall and only 1.7 rain days.
Are the municipal pools open in August?
Yes. The municipal summer pool season runs from 15 May to 6 September across 25 open-air sites, in fixed sessions at 2.25 € for an adult, so the whole of August falls inside the season rather than at its edge.
Which museums stay open later in August?
The Museum of Romanticism keeps its summer timetable to 8.30pm Tuesday to Saturday, and the National Archaeological Museum closes at 8pm all year. The Cerralbo, by contrast, still shuts at 3pm on every day but Thursday.

Yes, the regulated scheme runs normally on weekdays, capped at 4 hours in blue bays and 2 in green ones for non-residents. On Sundays and public holidays it does not operate, in August exactly as in any other month.
August does not close Madrid. It changes the timetable, and the timetable was the only thing worth checking.
