Essential Tips

What to Pack

Lightweight, moisture-wicking shirts - avoid cotton which stays wet in 70% humidity and 35°C (95°F) heat index

Compact umbrella and light rain jacket - afternoon storms develop quickly and produce heavy downpours lasting 20-30 minutes

SPF 50+ sunscreen and wide-brimmed hat - UV index of 8 can cause burns in 15 minutes on fair skin

Comfortable walking shoes with good grip - summer storms create slippery surfaces on downtown brick sidewalks

Portable phone charger - extended daylight hours and navigation needs drain batteries faster

Insulated water bottle - staying hydrated is critical when heat index exceeds 38°C (100°F)

Light cardigan or long sleeves - aggressive air conditioning in museums and restaurants can be shocking after outdoor heat

Waterproof phone case or bag - protect electronics during sudden afternoon thunderstorms

Electrolyte supplements or sports drinks - prevent heat exhaustion during outdoor State Fair activities

Cash in small bills - many State Fair vendors and local farmers markets prefer cash transactions
