Even if the temperature seems mild, the wind chill in Reykjavik can be biting. A good windproof jacket and accessories like a hat and gloves are non-negotiable.
Icelandic weather is famously unpredictable. Pack for rain, sun, and everything in between, often all in one day. A waterproof outer layer is your best friend.
With extended daylight, you have more time for sightseeing. Plan your days to take advantage of the extra hours, but remember to still prioritize rest with an eye mask.
May is becoming a more popular month for visitors. Secure your spots for popular tours, especially whale watching or Golden Circle trips, to avoid disappointment.
Unfortunately, seeing the Northern Lights in May is extremely unlikely. The extended daylight hours mean the sky is simply too bright to witness this phenomenon. The best time for Northern Lights viewing is during the darker winter months.
Comfortable, waterproof walking shoes or hiking boots are highly recommended. Reykjavik's streets can be uneven, and you'll likely do a lot of walking. If you plan any excursions outside the city, waterproof hiking boots are essential.
Not typically. Reykjavik's vibe is generally casual and relaxed. A nice sweater or a pair of dark jeans would be perfectly acceptable for most restaurants and bars. Comfort and practicality are usually prioritized.
Iceland is a largely cashless society. Credit and debit cards are widely accepted everywhere, even for small purchases. It's wise to have a small amount of local currency (ISK) for emergencies or very small vendors, but it's not essential.
Absolutely! Iceland boasts some of the cleanest and most delicious tap water in the world. Bring a reusable water bottle and fill up often – there's no need to buy bottled water.
While mosquitoes aren't a big issue in Iceland, you might encounter midges, especially near lakes or still water. They aren't harmful, but can be annoying. If you're particularly sensitive, a light insect repellent can be helpful, but generally isn't a major concern in Reykjavik itself.
