Sintra weather in July

We plan to visit Sintra in July and have found many inviting places to stay, but they don’t have air conditioning. Does Sintra’s microclimate really make a difference in the need for air-conditioning? Are days/evenings humid there? Would appreciate any personal insight on this. Thanks in advance.

Sintra covers a variety of altitudes, so it could be pretty cool in the hills but hot in the flatter areas. Air conditioning is not all that common in houses and apartments in Portugal, so it might be a challenge to find it. That said, Portugal- like a lot of Europe - is having hotter spells and July is a prime month for a heat wave.

If I would find something with AC, I would grab it. But, if you are in the hills or close to the coast, you would likely be ok. I’ve lived here (Cascais) through four summers and have turned my AC on 4-5 times each summer - if that gives you an indication of how regularly it’s really hot.

It’s fairly humid, being so close to the sea.
