Coastal areas are scorching, making them perfect spots for lazing on the sand, taking a dip in the sea, or trying your hand at some water sports. Certainly, these areas tend to be busy this time of year, but it does make for some great people-watching.

What about crowds and costs?

August is one of Portugal’s most popular months. It's the peak of the summer season, and you're likely to find a good deal of tourists flooding in. 

With schools out and sunny weather all around, expect the streets to be bustling, beaches packed, and attractions swarming with people. You’ll also want to factor in long lines at attractions during this month.

Now, when it comes to costs, get ready to dig a bit deeper into your pockets. August is when everything gets a bit pricier – particularly for accommodation, transportation, and activities. Tourist-related services often adjust their prices to meet the high demand.

In general, when visiting tourist destinations, you’ll want to try to plan to visit in the early mornings or late evenings to beat the crowds and the heat. Consider visiting lesser-known beaches such as Praia da Adraga, Praia da Foz do Arelho, or Praia da Amoreira.

If you're after similar weather but fewer crowds, think about swinging by Portugal in late June or early September. You'll still get that warm sunshine without the masses of tourists that flood in during August. It could mean a more laid-back vibe and possibly a bit easier on your wallet too.

But if you're set on August, make sure you book your accommodations and activities ahead of time. It's a hot spot for tourism, so places fill up quickly.
