A Swedish summer is warm in the afternoon, cool at 10 pm by the lake and often wet. Here’s what to bring for the weather you’ll actually get, and for the season’s three small hazards: ticks, mosquitoes and sun.
When you need this
You’ve booked a trip between June and August and you’re deciding how much to pack. Maybe it’s a city break in Stockholm or a week at a lake cabin. Maybe it’s the archipelago, a campsite, or the far north for the midnight sun and a mountain hike. Or you’re traveling with children and wondering about sun and ticks. This page covers the suitcase. The season itself — Midsummer, July holidays, booking — is in our guide to Sweden in summer.
How warm a Swedish summer really is
Milder than most visitors expect. SMHI, the national weather agency, gives these normal July means for 1991–2020:
| Place | Normal July mean | What it means for packing |
|---|---|---|
| Stockholm | 18.7 °C, the highest of any station | Light layers, one warm layer for evenings |
| Lund, Skåne | 18.3 °C | As Stockholm; August is the wettest month |
| Östersund-Frösön, Jämtland | 14.6 °C | A real sweater, not just a cardigan |
| Randijaur, central Lapland | 14.4 °C | Warm layer, rain jacket, head net |
| Kiruna airport | 13.2 °C | Pack as for a cool spring at home |
These are 24-hour means, so afternoons are warmer and nights cooler than the figure shown. Hot spells do happen — Överkalix in Norrbotten reached 34.3 °C on 26 July 2019 — so bring something for heat too. On some southern coasts August is slightly warmer than July. For every month and region, see Sweden’s weather month by month.
The clothes: layers and a rain jacket
The winter principle of several thin layers works in summer too, just with fewer of them. Pack light clothes for the day and one warm layer — a fleece or wool sweater — for evenings, boat trips and anywhere north of Stockholm.
Then pack a rain jacket. Summer is the wettest season at most SMHI stations: in Kiruna, July is the wettest month of the year at about 104 mm, and in Lund it is August. A light waterproof that packs small earns its place more than a second pair of shorts.
Heading into the mountains? Pack as for a cooler season, with a hat, gloves and a warm layer. Snow can lie on the high fell into June. Our hiking guide has the full kit.
Ticks and mosquitoes: dress for them
This is where a summer packing list for Sweden differs most from one for southern Europe. Ticks are reported from every Swedish municipality, and they carry Lyme borreliosis and TBE. 1177, the regions’ health service, advises:
- a long-sleeved top and long trousers, with the legs tucked into your socks
- covering shoes or boots in tall grass and forest, not sandals
- a full-body check every evening, with tweezers or a tick remover in your bag
Dark clothing attracts fewer ticks; light clothing makes them easier to spot, so pick your trade-off. Folkhälsomyndigheten, the public-health agency, says repellents give only limited protection — clothes do most of the work. If you’re staying in the Stockholm archipelago, a TBE risk area, consider vaccination, but start weeks ahead: good protection needs two doses, at least two weeks apart. Details in ticks in Sweden and TBE vaccination.
Mosquitoes peak from mid-June to early August in forest, bog and mountain birch, and drop clearly in August. The coast, the cities and the windy open fell are much milder. For a mountain trip in late June, pack long sleeves and a head net (myggnät). More in mosquitoes in Sweden.
Repellent is regulated here
In Sweden an insect repellent may only be sold or used once Kemikalieinspektionen, the chemicals agency, has approved it. Approved products carry a registration number on the pack. The label can set an age limit and a maximum number of applications per day, and those conditions are binding — never put repellent on a small child’s hands. Buying on arrival from a pharmacy, supermarket or outdoor shop is the simplest way to get a product that is legal here.
Sun protection that doesn’t trust clouds
Strålsäkerhetsmyndigheten, the radiation safety authority, advises protecting yourself when the UV index is 3 or higher — in a Swedish summer usually between 11:00 and 15:00. Clouds do not protect much, and water lets UV through to a swimmer. Its order of protection:
| Step | What to do |
|---|---|
| 1 | Take a break from the sun 11:00–15:00 |
| 2 | Use shade |
| 3 | Wear clothing: loose, tightly woven; a darker shirt protects better than a white one |
| 4 | Add a wide-brimmed hat and sunglasses |
| 5 | Use sunscreen as a supplement: SPF 15–25, or at least SPF 30 for high protection, reapplied after swimming |
Sunglasses matter on the water and on white sand: 1177 warns that reflected sunlight can damage the eyes. Children under one should not be in direct sunlight at all — bring a parasol, sun tent or pram cover. The Sweden with kids guide has more.
Light nights, water and the rest of the bag
North of the Arctic Circle the sun stays up around the clock; in Kiruna, from about 29 May to 14 July. Southernmost Sweden still gets about 17 hours of daylight at midsummer. Pack an eye mask if you sleep lightly, and ask whether your room has blackout blinds. Where and when to see it: the midnight sun.
The rest is short:
- A refillable bottle. Tap water on the public network is regulated as a foodstuff. See tap water in Sweden.
- A contactless bank card, and a spare. 92 % of in-store purchases are by card; see cards in Sweden.
- A light tent, if you want it. Allemansrätten lets you pitch for a night or two on most land without asking; see allemansrätten.
- Nothing for a campfire until you’ve checked the ban. Fire bans are set locally and shown on Krisinformation’s map; see fire bans in Sweden.
- A life jacket on every boat. Studies cited by Krisinformation found almost half of those who drowned after falling from a boat would have survived with one.
Guided mountain and water activities often lend some gear, but what’s included varies — check your booking before buying for one excursion.

FAQ
How warm is Sweden in summer?
Milder than many visitors expect. SMHI’s normal July mean for 1991–2020 is 18.7 °C in Stockholm, the warmest station, and about 13–14 °C in Lapland. These are 24-hour averages, so afternoons are warmer and nights cooler. Heat waves do happen: Överkalix reached 34.3 °C in July 2019. Pack for both, with layers.
Do I need a rain jacket in Sweden in summer?
Yes. Summer is the wettest season at most SMHI stations. In Kiruna, July is the wettest month of the year with about 104 mm, and in Lund in the south it is August. A light waterproof jacket that packs small does more for a Swedish summer than a second pair of shorts.
What should I wear against ticks and mosquitoes in Sweden?
Covering clothes. 1177 advises a long-sleeved top, long trousers tucked into socks and covering shoes or boots in tall grass and forest, then a full-body check every evening. Folkhälsomyndigheten says repellents give limited protection, so clothing does most of the work. For mosquitoes, add a head net in forest, bog and mountain birch in mid-summer.
Can I bring or buy insect repellent in Sweden?
You can buy it on arrival in pharmacies, supermarkets and outdoor shops. In Sweden a repellent must be approved by Kemikalieinspektionen before it may be sold or used, and approved products carry a registration number on the pack. The label can set an age limit and a maximum number of applications per day, and those conditions are binding.
Do I need sunscreen in Sweden?
Yes, as a supplement. Strålsäkerhetsmyndigheten advises protection when the UV index is 3 or higher, usually 11:00–15:00 in a Swedish summer, and says clouds and water do not protect much. Its order is a midday break, shade, clothing, a hat and sunglasses, then sunscreen of SPF 15–25 or at least SPF 30, reapplied after swimming.
How do I sleep during the midnight sun?
Pack an eye mask. North of the Arctic Circle the sun stays above the horizon around the clock for weeks — in Kiruna from about 29 May to 14 July. Further south it sets briefly, but southernmost Sweden still has about 17 hours of daylight at midsummer. Ask whether your room has blackout blinds or curtains.
Do I need cash in Sweden in summer?
Very little. The Riksbank’s 2026 payment report finds 92 % of in-store purchases are made by card, and card-only businesses are normal and legal. Pack a contactless bank card, and a spare one, rather than a wad of banknotes. Our guides to cards and cash in Sweden cover the few places where cash still matters.
