What to wear to Neopop Festival: Viana do Castelo sits at 26°C (79°F) by day and 17°C (63°F) at night in August, on beach, with a low chance of rain. That means a light base with one warm layer you can carry, flat sandals you can rinse, with trainers for the night stages, and a bag small enough for the gate rules. The crowd leans techno, underground and beach, so black and functional reads as insider.

Sand plus sun cream is the real enemy of a beach festival outfit. Anything with a rough weave will hold both, so smooth fabrics and rinseable shoes win.
Everything below follows from those numbers.
