What to Avoid

- Major holidays: Local school holidays and religious festivals drive domestic travel surges — popular spots fill up.
- Closures: Some sights and restaurants close during deep off-season. Verify business hours before booking.
Booking Tips
- Book flights 8-12 weeks ahead for peak season; 4-6 weeks for off-season usually works.
- Set Google Flights price alerts for your target dates.
- Watch shoulder weeks: the week just before/after peak season often has near-peak weather at 30% lower prices.
- Check local school holidays — these spike domestic travel and crowd major sites.
- Travel insurance is wise for any peak-season trip given high prices and harder-to-rebook flights.
The Sweet Spot: Why Late September Beats Both Summer and Spring
If you want one window to aim for, target the back half of September into the first week of October. Daytime highs sit around 26C in September and ease to about 23C in October, the Atlantic has been warming all summer so the beaches at Cascais and Caparica are still swimmable, and the August crowds have thinned. Hotel and flight prices soften noticeably once the school holidays end, which makes this stretch the genuine value pick over spring.
May is the other strong shoulder month, with highs near 22C, long dry days, and reliably low rainfall, but late spring rates have already started climbing toward summer. Peak runs June through August, when highs reach roughly 28C in July and August and the historic Alfama lanes get shoulder-to-shoulder.
One date worth planning around either way: the Festas de Lisboa. The Santo Antonio celebrations run from early June through the 15th, with the all-night street parties on 12 June and a city holiday on the 13th. Grilled sardines and neighborhood arraiais take over Alfama and Graca.
- Avoid November. It is the wettest month at around 135mm of rain, with grey skies that flatten the city’s famous light and shutter much of the outdoor terrace life.
