What to wear to Medusa Festival: Cullera sits at 31°C (88°F) by day and 23°C (73°F) at night in August, on beach, with a low chance of rain. That means loose natural fabrics and real sun protection, flat sandals you can rinse, with trainers for the night stages, and a bag small enough for the gate rules. The crowd leans rave, beach and neon, so anything that survives the day reads as right.
| Typical daytime high | 31°C (88°F) |
|---|---|
| Typical night low | 23°C (73°F) |
| Day–night swing | 8°C (14°F) |
| Rain risk | Low |
| Ground | Sand or pebbles |
| Sun exposure | High during the day, no shade at the main stages |
At 31°C (88°F), synthetic fabrics stop breathing and anything tight becomes uncomfortable within an hour. Cotton, linen and loose cuts outperform whatever looks best in a photo, and SPF is part of the outfit, not an extra.
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.
