Mammoth Lakes Summer Weather and Wildfires Basics

Winter and spring may bring bluebird days and nights next to the fire, but nothing makes as many outdoor activities possible as Mammoth Lakes summer weather.

Here at ASO Mammoth we believe that everyone should enjoy the mountain air and summer sun, so we’ve put together a short guide to Mammoth Lakes summer weather below! Read all about it, and then stop by the ASO Mammoth shop for the best outdoor gear and rentals in Mammoth Lakes!

Mammoth Lakes Average Summer Temperatures

As we mentioned here, Mammoth is mostly dry during the summer, with warmer days that average in the low 70s in June and high 70s in July and August. At night, temperatures drop to lower 40s in June and the higher 40s in July and August, so you’ll need a good jacket for the evenings.

Don’t Be Fooled by Cool Temperatures

Although that may seem like cool weather compared to your local summer temperatures, it’s important that you remember to stay hydrated even if you don’t feel hot. Mammoth Lakes’ high elevation means that your body must work harder to function than it would at normal altitude.

The immediate effect of Mammoth’s altitude may only be shortness of breath, but over time it can cause headaches, nausea, and dehydration, especially if you’re doing physical activity like mountain biking or hiking.

The best way to avoid being affected by Mammoth’s elevation is by drinking water throughout the day, so make sure you always have your water in hand!

Check The Air Quality Index Before Your Summer Visit

Like much of California, Mammoth Lakes is in a warm climate that receives little rain during the summer. Add in large wilderness areas and you have a recipe for wildfires.

Even if Mammoth Lakes is open for visitors, wildfires in the area can still cause the air quality to drop well below healthy levels. In fact, if the fire danger is high enough then wilderness areas may close to visitors all together in order to prevent manmade wildfires.

Wildfire danger is often at its highest during summer, so it’s important that you know what’s happening in the area before your summer visit. The best way to do that is by checking air quality trackers as well as weather forecasts which will give you a good idea of how high the fire danger may be.

You should also follow the Mammoth Lakes Fire Department on social media to be alerted anytime there is fire danger in the area.

You Must Follow All Fire Restrictions While Visiting

Keeping Mammoth Lakes and the wilderness areas that surround it open and safe for visitors and locals alike means following fire restrictions.

If there is a ban on campfires or an area is closed due to high fire danger, then you must follow those restrictions. We promise that the risk to the area and the people who live here is not worth it, and there is plenty to do in and around town if your outdoor plans are affected by fire restrictions!
