June

We have equal chances of experiencing above average temperatures in Indy this month. The average high temperature in June is 81º, but this week is already well above that — with forecasted temperature highs hovering in the low 90s. Similarly, precipitation will linger at the average mark in June, which means we can expect approximately eight days of rain. Sounds like perfect pool weather to us.

July

In July, the average high is 85º and the average low is 65º. Similar to June, the average amount of rainfall is eight days. We’re thinking that this will call for plenty of afternoons spent meandering through Indy’s parks followed by an al fresco dinner at a local spot.

August

The average amount of rainfall typically dips to seven days in August + the average high temperature is 83º. However, August 24, 2023 brought us Indy’s hottest day of the year, so that leaves us wondering — will we experience our hottest day of 2024 during this final month of summer? i>
