Northern lights in Pärnu tonight

Pärnu beach runs along the north shore of the town facing north-northwest across the Gulf of Riga toward Saaremaa island. The beach is 3 km long with a wide sand strand, and in winter the resort hotels are mostly closed, leaving the beach very quiet after dark. The town lights are behind to the south and the sea horizon to the north-northwest is substantially darker than looking inland. Bortle Class 3-4 from the beach depending on how far west you walk from the town illumination zone, and the position is accessible on foot from the centre across the pedestrian bridge.

Kihnu is a small Baltic island of 16 sq km with a population of around 600, listed as UNESCO Intangible Cultural Heritage for its living island culture. The island is flat with no buildings above two storeys and minimal artificial lighting, facing open Gulf of Riga water in all directions. The ferry departs from Pärnu harbour and takes approximately 55-70 minutes; the island has a guest house and further accommodation options, and the north and west shores give the darkest positions facing open water. Bortle Class 3 throughout, making Kihnu the most rewarding dark sky position accessible from Pärnu if you plan ahead for a minimum overnight stay.

Nigula is a raised bog and surrounding forest reserve in Pärnu County, one of Estonia's oldest protected nature areas, designated in 1957. The bog surface is flat and open with sightlines in all directions above the sedge and shrub layer, giving an unobstructed northern horizon. An 8 km boardwalk trail crosses the bog and is accessible from the trailhead car park on Route 7; the surrounding agricultural landscape is sparsely populated with minimal light pollution in any direction. Bortle Class 3 from the bog interior - the bog is wettest in autumn, so appropriate footwear is necessary.
