As the temperature drops and autumn sets in, Mother Nature is painting the treetops in vibrant hues of red, orange and gold, and many people are planning their leaf-viewing vacations.

SmokyMountains.com created a prediction map for the year's fall colors using millions of historical data points from the National Oceanic and Atmospheric Administration (NOAA).

"The predictive fall leaf map helps potential travelers, photographers and leaf peepers determine the precise future date that the leaves will peak in each area of the continental United States," Wes Melton, a data scientist and CTO of SmokyMountains.com, told Travel + Leisure.

"We believe this interactive tool will enable travelers to take more meaningful fall vacations, capture beautiful fall photos and enjoy the natural beauty of autumn," said Melton.

The color change of the leaves depends more on light than temperature, so it takes place at about the same time each year. But temperature, rain and other weather conditions can have an impact on the timing of the leaves' changing color. Thanks to warmer-than-average temperatures, fall is taking longer to come around for 2019. The good news is, with much of the U.S. having had an unusually wet summer, the tree are healthy and happy.

Here's a look at what to expect this fall if you're looking for colorful foliage.

Northeast

Peak time: There are a few patchy areas in the Northeast where leaves have already started to change, per SmokyMountains.com's map. The region may be at or near its peak by early October, and it'll be past its peak by late in the month. Fall foliage tends to peak for about one week around October 5th in Vermont, whereas the northern parts of New York and Vermont will be past their peak by mid-October.

Where to go: Walden Pond in Concord, Massachusetts, inspired Henry David Thoreau — when you see the autumn's colors reflected in the water, you'll understand why. The Catskills and Adirondacks are classic foliage destinations where you can catch several leaf peeping tours or simply wander among the vivid, leafy boughs on your own. Hike to the top of Hogback Mountain in southern Vermont and you'll be rewarded with a 100-mile view of orange, scarlet and gold.

The small town of Medfield, Massachusetts, is a quiet destination off the beaten path where you can walk six miles of footpaths through the gorgeous foliage at Rocky Woods State Reservation. New Hampshire's White Mountain National Forest guarantees spectacular leaf viewing each year. Climbing the tallest mountain on the U.S. Atlantic coast at Acadia National Park will give you a stunning view of the color-splashed landscape.

Southeast

Peak time: Some parts of the Southeast will have minimal to patchy color changes by the middle of October. The leaves are changing in North Carolina around November 2nd, but for peak foliage, aim to head outside around November 9th. If you give it a few more weeks, swatches of Virginia and Tennessee will be at their peaks. However, most of the region won't start to peak until early November, with the southernmost areas not peaking until the middle of the month.

Where to go: You'll never fail to get breathtakingly colorful views with a trip to Great Smoky Mountains National Park — there's a reason it's among America's most visited national parks. If you're looking to get a tour of what the Southern states have to offer, check out Alabama's Fall Color Trail, which will take you from the scenic views of Oak Mountain State Park to Cheaha State Park, the highest point in the state at 2,407 feet above sea level.

The overlook at South Carolina's Caesars Head State Park offers one of the most stunning views of autumn in the Appalachians, and a hike to nearby Raven Cliff Falls offers an ideal photo opportunity where water cascades down the dramatic 400-foot falls surrounded by fall colors. The city of Asheville, North Carolina, is a great stop if you crave a hip urban setting surrounded by gorgeous foliage. Georgia's Chattahoochee-Oconee National Forest always has spectacular views for leaf peepers. Arkansas' Ozark Mountain Region also promises an array of crimsons, yellows and oranges that offers many stunning photo opportunities.

Midwest

Peak time: The northern portions of Michigan, Wisconsin and Minnesota — will peak by early October. The rest of the region is expected to peak later in October.

Where to go: Michigan's Upper Peninsula is home to some of the most gorgeous fall foliage in the country, framing the area's more than 200 different waterfalls in a backdrop of spectacular color. Just 20 miles from downtown Cleveland, Ohio, sits Cuyahoga Valley National Park, a 33,000-acre preserve where you can spot bald eagles and other birds nestled among the leaves.

The Illinois River Road National Scenic Byway offers the opportunity to see autumn's splendor from a variety of viewpoints — from scenic bluffs to glistening waterways. Missouri's Katy Trail is the nation's longest rails-to-trails bike path, and it'll take you through small towns and farmland and give you breathtaking views of the Midwest's fall foliage.

Central U.S.

Peak time: The northernmost states in the region won't begin to really change up the colors until near the middle of October. Texas' leaves will change from November 16th through the end of November. In the northern part of the Lone Star State, you might see them at peak as early as November 9th.

Where to go: They may be called the Black Hills, but this area of South Dakota is blanketed in a variety of colors every autumn. Leaf peepers looking for an overview of what the area has to offer should take a drive along the Spearfish Canyon Scenic Byway.

Montana's Glacier National Park offers breathtaking views at all times of year, and fall is no different. Although the park is home to many evergreens, you'll also see bright yellows and crimsons, which creates a stunning contrast among the greens. Nestled in the Missouri River bluffs in northeastern Nebraska, Ponca State Park offers gorgeous landscapes dotted with fall colors and Texas has more to offer than just cacti — Lost Maples State Natural Area is a great place to see some of fall's best oranges and yellows.

Northwest

Peak time: The leaves will start to visibly change in Washington state around October 1st, and peak around October 12th. You may be able to see peak foliage as late as October 26th in southern parts of the region.

Where to go: The Columbia River Gorge National Scenic Area that spans southern Washington and northern Oregon is typically an ideal place to see the colorful show put on by the area's maples, cottonwoods and ash tree. The Mount Baker-Snoqualmie National Forest in Washington is home to gorgeous creeks and lakes that reflect the colorful foliage, and Mount Rainier National Park boasts brilliant fall colors, thanks to its vine maples, huckleberry bushes and larch trees.

Oregon's 2.3 million-acre Fremont-Winema National Forest offers many scenic vistas of vibrant oranges and yellows, and Idaho's Teton Scenic Byway is a must-see with its variety of colors dotting the mountain range. You might be surprised to find so many hues in Alaska's Denali National Park, but the area's breathtaking beauty gets much more colorful in the fall. Keep in mind that fall starts early and ends quickly in Denali, so make your way up there in late August or early September to catch the park's brilliant reds and oranges.

Peak time: Northern California will see the peak of the season from about October 26th through November 9th. If you're down south, plan to head out November 9th through mid-November. Some parts of the Mountain West are already receiving their first snow of the season, which will dampen fall foliage.

Where to go: Aspen may be known for its skiing, but every autumn the golden foliage of the town's namesake tree makes the area's slopes worth the trip — even without snow. The leaves begin changing in Arizona's Coconino National Forest as early as September, but the gold rush really begins in October.

New Mexico's Sangre de Cristo mountains are splattered in orange, gold and yellow every fall and offer a wealth of photo opportunities. You can never go wrong with a trip to the Lake Tahoe area during this time of year. The fall color show lasts for weeks here, and the gorgeous foliage provides the perfect backdrop for the variety of outdoor activities available at Lake Tahoe.
