Re: Lisbon weather in september??? Lisbon has classic Mediterranean climate all year around with brighter hot summers and cool winters. The peak season is from June to September and during this time many people come for golfing holidays, so everything is expensive. As well as May and June, September is the most sun-drenched month. A good month to visit Lisbon will be September, so if you plan your trip in early September then it would be perfect. |
