Spring in Slovenia, three very different months

March, spring with snow

In March the average in Ljubljana is 6.8°C according to official statistics for 2001 to 2010, and snow still rules the mountains. It’s Planica’s month, with the 2027 ski flying set for 18 to 21 March, and it’s when the legal winter equipment period for cars ends, on the 15th. Kanin, above Bovec, is the resort that holds on to natural snow longest. The month in detail is in Slovenia in March.

April, when things reopen

April brings two changes you notice. Vintgar Gorge opens its season, which lasts until October, and Bled Castle starts closing at 8pm rather than 6pm. Ljubljana’s average rises to 11.3°C, though it rains, 105 mm, and the high mountains stay below freezing, at -3.2°C on Kredarica. Nothing opens on 27 April either, the national holiday that commemorates the uprising against the wartime occupation. For me the second half of April is the sweet spot, as I explain in Slovenia in April.

May, the best of spring

In May the average reaches 16.6°C in Ljubljana and 17.5°C at Portorož, and Kredarica finally rises above zero. The 1st and 2nd are holidays, and the 20th is World Bee Day, linked to the Slovenian beekeeper Anton Janša. The lakes at Bled, Bohinj and Jasna are in season, with far fewer visitors than in July. It’s all in Slovenia in May.

Bohinj’s wild flowers

If there’s one spring plan I find special, it’s this one. Bohinj’s International Wild Flower Festival is held every May and June across several of the valley’s 24 villages, with botanical walks, events and cooking with wild plants. 2026 was its 20th edition, from 22 May to 7 June, and the organisers point out that Triglav National Park is home to more than a thousand plant species. For 2027 you’ll need to wait for the valley to publish its programme. I find it a lovely way to experience Bohinj as more than a postcard lake. The valley is covered in Bohinj.

What I wouldn’t do in spring

Heading into the high mountains before late May without snow experience. The figures make it clear, and the valleys have plenty to offer. I also won’t give you the 2027 dates for Easter and Whitsun, which bring work-free days, because they weren’t on the official calendar I checked. When they’re out, it’s worth looking, because they affect how busy the weekends get.

So you do not lose the morning at the ticket office, browse tickets and tours in Bohinj on GetYourGuide.
