Northern lights Riga tonight
Riga sits at ~58°N magnetic latitude and needs Kp 4-5 for aurora. Cape Kolka at the tip of the Courland Peninsula is Latvia's best dark sky position - 180 km north-west with Bortle 2 sky facing the open Baltic. Gauja National Park is 60 km away for quicker access. Aurora is visible during G1-G2 storms on clear nights. Best season: September to April.

What Kp is needed here?
Riga sits at a magnetic latitude of approximately 58°N. The Kp index - a global measure of geomagnetic activity on a scale from 0 (quiet) to 9 (extreme storm), updated every 3 hours - needs to reach Kp 4–5 before the auroral oval expands far enough south to be visible from here.
At Kp 4–5, visibility is possible from Riga but skies need to be clear and dark. Cloud cover and light pollution remain the main obstacles even when Kp is high enough.
Best dark sky sites near Riga
Light pollution is the biggest obstacle after cloud cover. These sites give you the best dark northern horizon within reach.
Cape Kolka (Kolkasrags)
The northern tip of the Courland Peninsula, 180 km north-west of Riga along the P128 coast road. Cape Kolka faces north-west over the Baltic Sea at the point where the Gulf of Riga meets the open Baltic. Slītere National Park surrounds the cape with Bortle 2 sky - one of the darkest accessible positions in Latvia. The Kolka lighthouse area gives an elevated north-west-facing position. This is Latvia's best aurora viewing spot: the combination of northernmost latitude (57.7°N geographic), open ocean horizon, and deep darkness is the equivalent of a Scottish headland. The 2-hour drive from Riga is the trade-off.
Gauja National Park (Vidzeme)
Latvia's largest national park, 60 km north-east of Riga via the A2 highway to Sigulda. The open areas above the Gauja river valley give north-facing sky with Bortle 3-4 conditions. The park town of Sigulda is 50 km from Riga - accessible in under an hour. Less dark than Cape Kolka but practical for a quick response when a storm develops unexpectedly on a clear evening. The hill ridges above the valley give unobstructed northern horizons.
Jūrmala coast (Gulf of Riga)
The resort town of Jūrmala, 30 km west of Riga along the A10 motorway, faces north over the Gulf of Riga. The pine forest beach gives modest darkness (Bortle 4-5) and a north-facing open water horizon. The quickest dark-sky option from central Riga - 30 minutes by car or train. At Kp 5+ aurora may appear on the northern horizon across the gulf despite the moderate light pollution. Best suited as a fallback when a stronger storm develops unexpectedly and driving further is not possible.
