Essential Tips

Waterproof jacket or umbrella - April brings 10 rainy days with afternoon thunderstorms lasting 45-90 minutes each

Comfortable walking shoes - Indianapolis requires lots of walking on concrete sidewalks and the 13 km (8 mile) Cultural Trail

SPF 30+ sunscreen - UV index reaches 8 on clear days, and spring sun reflects strongly off downtown glass buildings

Warm evening layers - Temperatures drop to 4°C (39°F) after sunset, essential for outdoor dining and events

Light gloves and hat - Early morning activities like sunrise balloon rides or early brewery tours can feel like 0°C (32°F)

Casual spring clothes - Indianapolis is decidedly casual; even upscale restaurants accept jeans and nice shirts

Allergy medication - Spring pollen from maple and oak trees peaks in April, affecting sensitive travelers

Portable phone charger - Extensive outdoor exploration drains batteries, especially using GPS and photography apps
