Guide to 2023 Summer Events & Festivals in Simi Valley

summer events in simi

In Simi Valley, the living’s always nice, easy, and breezy. But in the summer months, Simi Valley can be extra special. For many reasons.

First off, there’s the region’s coveted Mediterranean climate. While the mercury creeps toward triple digits in parts of Los Angeles and other nearby valleys like the San Fernando Valley, average high temperatures in Simi Valley sit at 82 degrees in July and 83 degrees in August. It’s hard to beat that.

No matter what you choose to do here in the summer, you’ll be able to do it in comfort, with the sun shining on your face—minus the sweat dripping down it. You won’t feel like you’re melting. You’ll just feel…cool. Like the overall vibe of Simi Valley.

Of course, there’s plenty of activities to choose from during summer in Simi Valley. Including an array of events and festivals. Let’s take a closer look at some of the 2023 summer offerings now.
