September is still a popular time but generally less crowded than peak summer months (July/August).

Accommodation costs vary: a hostel bed might be an estimated €25-€45 per night, a mid-range hotel €80-€150 per night, and higher-end options €150-€300+. Availability is generally good, but booking a few months in advance is recommended, especially for weekends, to secure better prices and options.

What Can You Expect (Crowds, Events, Conditions)?

Expect moderate crowds, noticeably fewer than in August, but popular attractions like the Guggenheim Museum and the Casco Viejo (Old Town) will still be lively. The conditions are excellent for walking and exploring the city on foot. While major summer festivals have concluded, Bilbao often hosts various cultural events, art exhibitions, and gastronomic fairs throughout September. The sea temperature may be cooling, but early September can still be pleasant for beach visits to nearby coastal towns.
