Can you see the northern lights in Alabama tonight?

Unlikely: Kp 1.33 at 2:04 PM CDT falls short of the Kp 9 or so that Alabama's northern horizon requires.

Kp from NOAA SWPC estimated planetary K index. The NWS BMX gridded forecast provides cloud cover for Cheaha State Park.

At Cheaha State Park, nautical darkness begins at 7:13 PM and holds until 5:48 AM CDT. Tonight's moon, in its waning crescent phase, shows 14 percent lit. The sun and moon positions, computed for the date and the viewing spot, supply both numbers, and no forecast plays a part.

What is Kp?

A 0-9 scale called Kp rates the current disturbance of Earth's magnetic field. Its name comes from planetarische Kennziffer, German for planetary index. Thirteen observatories worldwide take the measurements. Higher values mean the aurora reaches further south. Most of the northern US needs a Kp of 5 or higher, while northern Alaska sees it at Kp 0. Full Kp guide.

Why Alabama needs Kp 9

Because the aurora follows the magnetic field rather than the equator, geomagnetic latitude matters more than map latitude. At Alabama's northern edge, the reading is 44.0° geomagnetic; the oval only draws level with that latitude at about Kp 9, and the Kp number already includes roughly 5 degrees of cushion, because the high-altitude aurora hangs low on the horizon.

Where to watch from in Alabama

All three spots in Alabama can differ in cloud cover, so all three are worth a look. Bankhead National Forest looks clearest tonight, at 2% cover.

Cheaha State Park, near Oxford, is the spot to try when Alabama gets a shot at northern lights. That takes a NOAA G5 extreme storm, Kp 9, which occurs only about four days per 11-year cycle. Bankhead National Forest near Double Springs is another dark option. Joe Wheeler State Park near Rogersville offers a third choice.

Can the northern lights reach Birmingham, Huntsville and Mobile tonight?

CityKp neededRight now

Each city's Kp value comes from its own coordinates and geomagnetic latitude, so the further south a city is in the state, the higher the Kp it needs.

Cloud cover, averaged over tonight's viewing window for each location, comes from NWS gridded forecasts.

Was there aurora last night in Alabama?

The night of October 6 topped out at Kp 2.33, short of the 9 Alabama needs, so the aurora stayed out of range.

The most recent night in range was May 10, 2024, when the night's highest Kp reached 9.00.

0 nights so far in 2026 have been in range for Alabama, against a yearly average of 0.1 across the complete years since 1994. The year's highest night Kp so far is 8.67, set on January 19, 2026.

Local time 9 pm to 3 am is the span of a night. The night's Kp is the highest among the three hour windows overlapping those hours. A night is in range when that Kp reached the threshold the state needs, which comes from where the northern edge of the state sits in geomagnetic latitude. Cloud is not in the record, so in range means the aurora was in range, not that anyone saw it. Figures are NOAA Space Weather Prediction Center daily geomagnetic data from 1994 on.
