Seasons, Days, and Times
Best Season
The shoulder seasons of Spring (April-June) and Autumn (September-November) are ideal. The weather in Lisbon is pleasant, and the crowds are smaller than in the peak summer months of July and August. Winter is the quietest but can be cool and rainy.
Best Day of the Week
Weekdays, especially Tuesday to Thursday, are significantly less crowded than weekends. Avoid Sundays if possible, as free entry for residents in the morning attracts large crowds.
Best Time of Day
The best time to visit is early in the morning, right when the tower opens at 10:00 AM. This allows you to explore before the large tour groups arrive around midday. Alternatively, visiting in the late afternoon, about an hour before the last entry, can also be a quieter experience with the added bonus of beautiful light for photos.
