If you go to the furthest away beach with the basic loungers (not the posh ones) it's around £15 euros and the best cafe is Absurdio next to this beach. Ask Angelo on the beach!

The sandy beach itself has loungers, and on the prom are smashing shaded areas with waiter service. If you don`t bring towels yourself, you can buy them cheaply nearby at kiosks. Most folk dry off quickly in the sun, after all it is June when you are coming

Si, por supuesto. Unos cuartos de baños muy amplios y el agua con mucha presión

No estoy seguro.

Quantos Kms exatos, não sei. Só sei que é muito prazeroso o passeio em dias de sol.

two beds and umbrella cost 15€/day. we were there in juni 2017. there are palm trees on the beach. it is very nice, big and beautiful beach. there were windy, that's true.. but i don't know if you go in August.. you can also use your own umbrella. many people had own umbrella too.. it is your choice.

Similar to others; we were charged 12,50 euros for two beds on a Monday and then 15euros for two beds plus umbrella on a Sunday.

Temperature will likely be between 12Cº and 19Cº, not beach weather, with a bit of luck there will be no rain and some nice sunny winter days. You need warm clothing. Enjoy your holiday, you will just love Cascais
