When to go, and when not to
Lisbon's best months are May, June, July, and August, which line up with the highest visit scores of the year. Sunshine climbs to between about 12.5 and 13.3 hours a day in this stretch, rain nearly disappears with as low as 0mm in August, and highs range from about 23.4C in May to 30.1C in August, with lows staying mild.
Peak season brings trade-offs: August is the hottest month at a high of 30.1C, and the same months that draw the most sunshine also draw the most visitors, pushing up demand for lodging. Travelers who prefer cooler, wetter conditions with fewer crowds can look to the off season, when rain rises to 113mm in January and 110mm in November and highs drop into the mid-teens Celsius.
