As far as the weather goes, May is usually a good month to visit Lisbon. Most days already feel like summer.
Every once in a while there may be a partial rainy day, but it won’t be a couple of hours until the rain passes.
Weather in May: What to Pack, What to Wear
- Average High: 22ºC (72ºF)
- Average Low: 14ºC (57ºF)
This month may have a few days when the thermometer goes over 30ºC (86ºF).
Lisbon receives on average 53mm of rainfall during May. Occasional thunders are not unusual.
Layers may come in handy during your May visit to Lisbon. Layers will allow you to be prepared if it becomes windy, or the weather suddenly changes. We recommend bringing along a light weight jacket as well as a number of short sleeve shirts. Long pants or jeans are what the locals wear, but there are a few days where you could wear shorts.
Events in May
- Indie Lisboa: An independent 11-day film festival that offers documentaries, shorts and experimental film exhibitions (both Portuguese and foreign) of all genres.

- ARCO Lisboa: This international contemporary art fair brings together emerging and renowned artists in an event that promises to have an impact on the Portuguese contemporary art market.
The best scenic view of Lisbon is from the river Tejo. There are several tour boats that vary in price and duration. Choosing the right one for you is easier if you read about boat trips in Lisbon.
