Choose the outing, not the longest itinerary.
For August, one well-chosen outing can be more enjoyable than a day spent crossing the city. Leave space for a shaded pause, a long lunch or an indoor visit when a walk stops feeling comfortable.
For Lisbon in August, use the monthly climate as planning context, then check the daily forecast closer to your trip. Choose a date in the calendar for programmes with published dates, and keep longer exhibitions and festival periods separate. Pick one indoor option and one neighbourhood stop so the day can stay flexible.
SEASONAL AVERAGE · NOT A DAILY FORECAST
IPMA · Instituto Geofísico station 535 · 1991–2020 monthly normals. These are not daily extremes, a forecast for this year or a count of rain days already observed.
The forecast covers only the next seven days when available. Later travel dates keep their seasonal averages until a forecast is published.

Programme until 31 Dec 2027
Museu Banksy Lisbon, Rua Viriato 25B, Lisboa
Graffiti, films and installations introduce Banksy’s political and social ideas. The museum displays reproductions, not a collection of original street works—useful to know before choosing this stop.

Fundação Calouste Gulbenkian - Centro de Arte Moderna
CAM uses the storytelling world of One Thousand and One Nights to explore its collection. Think gallery visit and stories told through artworks, not a staged performance of the tales.

Programme until 20 Sept 2027
Fundação Calouste Gulbenkian - Centro de Arte Moderna
See collection works that usually stay out of the galleries, in a space also used by museum professionals. This is a supervised, limited-capacity visit; check the published entry slots before arriving.

MACAM
MACAM’s permanent display follows the two phases of Armando Martins’s collecting.

The exhibition occupies Galleries 1 and 2; a chapel visit is not included in this ticket.

Look at the current temperature, wind and warnings before a beach or boat plan. The summer climate average is not a guarantee about any particular day.
The figures above are the 1991–2020 monthly climate normals for Lisbon's Instituto Geofísico station. An average daily high or low is not an extreme, and an average rain-day count does not tell you which days will be wet. Check the daily forecast and current warnings before an outdoor commitment.
A garden, a museum and dinner can work as well as the coast. Confirm holiday service with the restaurant or operator you actually want; this guide does not turn a season into an opening-hours promise.
Choose a meal near the part of the city you want to explore. Our neighbourhood and food guides keep the existing place notes, branch details and saved-list links together. For a bigger route, Plan my days can combine places with announced dated sessions; the final booking stays with the venue.
Numbers on the dates count programmes with published single dates or explicit session dates, not a ticket for each listed idea. An exhibition period or booking window never turns into a session on every date between its endpoints. Select a day to see its dated programmes and the separate longer periods.
The event and festival lists come from our existing saved programme sources. They are partial coverage, not everything happening in Lisbon. Check the organiser's session, language, age, access and ticket terms before you arrange the rest of the day. A dated programme is not evidence of a seat being available.
Sunrise and sunset here are calculated for the public city-centre reference point and the displayed date, in Lisbon time. They are rounded estimates, not a forecast of visible sunshine; hills, buildings and clouds change what you actually see.
Use the date with a reservation time and check the return journey for a late evening. A sunset estimate, an ordinary Metro operating window and a specific transport connection are different pieces of information.
If the weather or a booking changes, shorten the outdoor stretch rather than replacing it with three distant stops. A café, an indoor visit or a workshop from our guide can give the day a new shape without starting again from scratch.
Save the places you want to keep to My Lisbon on this device. For a ticketed activity, keep the confirmation and exact meeting point available before you leave. The monthly programme can change, so revisit the organiser's information close to the date.
No. It uses IPMA's 1991–2020 monthly climate normals. The average low, high and number of days with at least 1 mm of rain are seasonal context, not a prediction for individual travel dates.
Do not assume so. Calendar counts use explicit published dates. Longer programme periods are shown separately; use the organiser's own session or opening information before booking.
The calendar shows the next occurrence of August within the current twelve-month planning window. The displayed year applies to the announced events; the climate figures are historical monthly averages.
