Experiences with Portugal weather in September?

[Scuba]

I remember Paris hitting 97 in early June. Avignon high 90s mid-September.



Southern Spain can reach 120 degrees in August - it’s like SE Arizona in the summer.



So we tend to only visit Northern European countries in the summer, late May and early Sept.

One thing that may not be important to some but is for us is water temperature. Water temperature lags air temperature, so typically the sea is warmest in August and September. When we were in Greece for six weeks, we spent a fair bit of time on beaches and in the sea. September was perfect weather for this!

Same for us. We were swimming in Sicily in mid October. Water was perfect....and warm.

These weather questions are a little iffy...just like the the weather forcasts. You just never know what you will get.

It appears that Portugal (Lisbon, Obidos) has decent temperatures but the humidity is perhaps a concern?

Depends on your tolerance for humidity. Check Weatherspark for places you've lived. How did you fare during the 'muggy' periods?

Any experiences that others have had traveling in Portugal in September?

Somebody once said climate is what you expect, weather is what you get.

I was in Caldas da Rainha from mid-Sept to end of Oct this year. It's about 45 miles North and on the other side of a mountain range from Lisbon. It was delightfully drier and warmer than climate averages. At the same time Lisbon had highs 10-25 degrees above historical averages. Note actual vs historical for 22nd - 24th of Sept at https://www.accuweather.com/en/pt/lisbon/274087/september-weather/274087 Also note that because of the cost of electricity, air conditioned accommodations are not the norm in Portugal.

Had a friend who went to Portugal and enjoyed everything except the bed bugs. It pays to check.
