What to wear to Rainbow Serpent Festival: Lexton sits at 31°C (88°F) by day and 13°C (55°F) at night in January, on open field, with a low chance of rain. That means loose natural fabrics and real sun protection, broken-in boots or sturdy trainers, and a bag small enough for the gate rules. The crowd leans psy, goa and costume, so a full costume is the norm rather than the exception.
| Typical daytime high | 31°C (88°F) |
|---|---|
| Typical night low | 13°C (55°F) |
| Day–night swing | 18°C (32°F) |
| Rain risk | Low |
| Ground | Grass that turns to mud |
| Sun exposure | High during the day, no shade at the main stages |
The 18-degree swing is the thing to solve. The outfit you choose at 3pm has to still work at 2am, and layers you can carry beat a second trip to the car or tent.
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.
Everything below follows from those numbers.
