Crater Lake National Park sits high up between 7,000 and 8,000 feet. This altitude creates some wild weather patterns that really change when you can get to trails, roads, or even basic park facilities.
Because the park sits so high, winters get pretty brutal, with heavy snow that often sticks around from November all the way into early May. Summers, on the other hand, are short but seriously beautiful, with warm days and clear skies that feel like a reward after all that snow.
If you want the best weather, aim for July through September. That’s when temperatures usually hit comfy highs around 70°F, and all the roads and trails finally open up. Rim Drive fully opens, hiking trails clear up, and you can get out on a boat to see the lake’s deep blue water up close.
Of course, you won’t be alone. This is when most people visit, so expect crowds.
Weather at Crater Lake changes a lot depending on the season. It affects everything—road access, activities, and even your overall experience. If you know how the seasons work in different areas, like Rim Village or along the scenic drives, you can plan a trip that fits your favorite activities, crowd tolerance, and budget.
How Weather Influences the Best Time to Visit
Weather at Crater Lake National Park swings wildly as the year goes on. Each season brings its own perks and headaches.
The park’s high elevation means you’ll see big temperature swings, heavy snow, and all kinds of precipitation patterns. These directly shape what you can do and how you get around.
Year-Round Climate Overview
Crater Lake National Park sits up at 6,178 feet, which gives it a mountain climate. Winters get harsh, summers stay mild, and the park sees some of the heaviest snowfall anywhere in the U.S.
From November through April, temperatures often dip below freezing. Snow can pile up to 10 or even 15 feet during the peak months. Most roads shut down because of all that snow.
Spring can’t really make up its mind. Snow lingers at higher elevations, and many trails stay closed until late June or July. You might get some warmer days, but nights can still freeze.
Summer is the most dependable. Temperatures swing from the 40s at night up to the 70s or 80s during the day. This is when you actually get reliable access to everything in the park.
Fall changes fast. You could get a warm, sunny day or a sudden snowstorm. By October, snow starts to stick again.
Temperature Patterns and Extremes
During July and August, summer temperatures usually hit the 70s or low 80s (Fahrenheit). Nights cool down fast—often into the 40s—even at the height of summer.
Because the park is so high, you can feel a 30 to 40-degree difference between day and night. It’s pretty wild.
Winter gets cold. Highs in January hover around 30°F, and nights often drop below 10°F. Wind chill can make it feel even colder.
October is a transition month. Highs average about 52°F, lows near 31°F, but those numbers can change fast if a storm rolls in.
Spring can be all over the place. May highs get into the 50s, but nights still freeze. And honestly, you can see snow in any spring month.
Precipitation and Cloud Cover Trends
Most of Crater Lake’s precipitation falls as snow, from November to April. The park averages more than 500 inches of snow a year, making it one of America’s snowiest spots.
July through September bring the driest weather. Rain is rare, so hiking and camping become way easier.
October averages about 21 inches of snow. Some years you might get more, some less. Early fall storms can drop a ton of snow without warning, shutting down roads and trails.
Cloud cover follows the same pattern as the snow. Summers have the clearest skies and the best views. Winters get socked in with clouds, sometimes for days on end.
In spring, you’ll see both rain and snow. Weather systems can blow through quickly, so you might go from sunshine to a storm in just a few hours.
Summer at Crater Lake: Advantages and Considerations
Summer really is the sweet spot for weather at Crater Lake. Temperatures hit the mid-70s, and you finally get full access to all the park’s facilities.
Naturally, everyone else wants to visit then too. You’ll need to plan ahead for places to stay and for the most popular activities.
Typical Weather Conditions in Summer
In July and August, you’ll usually see temperatures from 40°F to 78°F. Days feel just right for being outdoors.
Nights cool off a lot because of the elevation (7,000-8,000 feet). Definitely bring some warm layers for evenings.
Summers stay dry, with barely any rain. The skies are clear and the lake views are incredible.
By July, the snow is finally gone. You can see the full sweep of canyons and forests. Wildflowers pop up during this short window too, adding a splash of color everywhere.
Activities and Accessibility in Peak Season
Rim Drive opens up completely in summer, so you can drive the whole 33-mile loop around the lake. From November through May, snow closes it down.
All the hiking trails open, including Cleetwood Cove Trail, which is the only way down to the lake. Boat tours out to Wizard Island run only from July to September.
Here’s what else opens up in summer:
- Crater Lake Lodge (mid-May to mid-October)
- Rim Visitor Center (summer only)
- Food and gift shops (full hours)
- Ranger programs (late June to mid-September)
Camping, fishing, and photography all hit their peak in summer. You can even swim in designated spots—just know the water’s cold no matter what.
Visitor Numbers and Crowds
Summer is when almost everyone visits. The short season means crowds get packed into just a few months.
Parking lots fill up fast, especially at popular viewpoints. If you want a quieter experience, come early in the morning.
Book your accommodations early. Crater Lake Lodge and nearby hotels get snapped up months ahead, especially for July and August.
Popular trails like Cleetwood Cove can get crowded. Expect to see plenty of other hikers.
Still, if you want full access to everything, summer is your best bet.
Winter at Crater Lake National Park: Unforgettable Snow Experiences
Winter turns Crater Lake into a snowy wonderland. The park gets up to 42 feet of snow a year, making it one of America’s snowiest destinations. If you love snow sports or winter photography, this is your season.
You can still visit, but you’ll need to use certain routes and be ready for a totally different set of activities.

Most other roads close. Rim Drive, for example, shuts down to vehicles around late October.

The park itself stays open 24/7 year-round, but visitor services run on a reduced winter schedule.
Popular Winter Activities and Safety Tips

Pros and Cons of Visiting in Spring
Spring means fewer people and cheaper places to stay. Hotels nearby knock about 20% off their rates compared to summer. Crater Lake Lodge usually opens in mid-May with lower prices.
But you’ll run into some issues. Many hiking trails stay buried under snow. Rim Drive is closed from November through May.

September sometimes features special events like Ride the Rim, when Rim Drive closes to cars and cyclists get the whole road to themselves.
Fall Activities:
- Photographing the changing landscape
- Watching wildlife
- Hiking in cool weather
- Biking on Rim Drive
By October, the first snow dusts the park, making the blue lake pop even more. Fall colors show up in a few spots, but the park doesn’t have many deciduous trees because of the elevation.

Weather-Based Planning Tips for Your Park Visit
Weather at Crater Lake is unpredictable, so you’ll want to prep differently depending on when you visit. What you pack and what you plan to do will depend a lot on the season.
Choosing Travel Dates by Activity Type
Hiking and Trail Activities work best from July through October, after the snow finally melts. Daytime temperatures usually sit between 65°F and 80°F, so you can stay outside comfortably.
Photography and Lake Viewing can happen any time, but your experience changes with weather conditions. Summer gives you crystal-clear views of the lake’s blue water. Winter brings dramatic snow scenes, but you’ll need to be flexible since conditions can change fast.
Snow Sports and Winter Activities peak from December to May, once there’s enough snow at higher elevations. Snowshoeing and cross-country skiing become options as soon as the snow is deep enough.
Wildflower Viewing starts when the snow melts in lower areas and keeps going through September. The timing depends on how fast the snow disappears and how warm spring gets.
What to Pack for Each Season
Summer Packing (July-September):
- Bring layered clothing since temperatures change a lot.
- You’ll want a warm jacket—nights can drop to around 40°F.
- Don’t forget sunscreen and a hat, that sun at high elevation feels relentless.
- Pack rain gear, those afternoon thunderstorms come out of nowhere.
Winter Packing (December-May):
- Go for insulated, waterproof clothing.
- You’ll need traction devices if it gets icy.
- Toss in emergency supplies like food and water, just in case.
- Extra batteries are a must because cold drains them fast.
Shoulder Season Packing (May-June, October):
- Waterproof boots help with all the mud.
- Wear multiple layers since the temperature jumps around a lot.
- Rain protection is smart—expect frequent showers.
- If you’re camping, warm sleeping gear is essential.
Safety and Road Conditions
Weather at Crater Lake can flip fast and mess with road conditions. Heavy snow closes the North Entrance every season. Always check the latest conditions before you set out.
Driving in winter? Snow and ice cover the roads, so you’ll need chains or four-wheel drive. Sometimes the weather goes from clear to dangerous in just a few hours.
In summer, afternoon thunderstorms roll in quickly. Wildfire smoke can make the air pretty rough, especially later in the season.
No matter when you go, check the weather forecast more than once before you leave. Cell service barely works in most of the park, so plan well ahead to stay safe.
Iconic Areas: How Weather Affects Rim Village and Rim Drive
Weather shapes what you can see and do at Crater Lake’s most famous spots. Rim Village sits way up at 7,050 feet. Rim Drive wraps around the caldera between 7,000 and 8,000 feet.
Rim Village Access and Views
Rim Village stays open all year, but the weather really changes how you experience it. In winter, snow piles up—sometimes 21 feet deep. That makes walking near viewpoints risky and parking harder to find.
Summer is a different story. From July through September, you’ll get the clearest views. Fog and rain rarely get in the way, so you can actually see the whole lake.
Spring weather at Rim Village is unpredictable. Snow sometimes falls in May or even June. Temperatures can swing 30 degrees in a single day up here.
If you visit in winter, expect tough conditions. Snow blocks a lot of walkways. Ice turns the paths slick and risky. When storms hit hard, the visitor center might close.
Rim Drive Openings and Closures
Rim Drive’s 33-mile loop really depends on the weather for accessibility.
Usually, the full drive opens from mid-July to mid-October each year.
Snow piles up fast and often forces closures that can stretch out for up to eight months.
Partial access changes with the season and how much snow is on the ground.
The south entrance to the Steel Information Center usually opens by late May, but honestly, it depends.
The north section just stays closed until all that heavy snow finally melts away.
Weather stations keep an eye on conditions at different elevations along Rim Drive.
Wind sometimes gets wild at the exposed viewpoints, and you can feel it.
Rain and snow make driving pretty slick on those narrow mountain roads.
Park crews watch the weather forecasts and measure snow depth before they plow each section.
Even a small storm can make them close the road temporarily—safety comes first.
If you’re thinking about driving, check the current conditions before you go.
