What Is Good Weather in Iceland
Ask a tourist what good weather means, and you'll get something predictable. You will likely hear about sunshine, warmth, maybe a light breeze, and a temperature that lets you wear shorts without thinking about it. Ask an Icelander the same question, and you'll get a very different answer. You might get a long pause first because the question is complicated. Then you'll probably hear something like: "Well, it depends on the wind." Or: "Is the sun out?" Or, if you're lucky, the honest answer is, "Anything that isn't actively trying to kill me."
So, when locals talk about good weather, we're not talking about the same thing visitors are. Here's what we actually mean.
The Wind Is Everything
Before we talk about temperature, we have to talk about wind. Wind is the single most important variable in Icelandic weather, full stop. It is what determines whether a day is pleasant or miserable, and almost every tourist underestimates it until they experience it. A still, sunny day at -5 degrees Celsius is beautiful. You'll see kids playing outside and people walking their dogs without rushing. The cold is refreshing, waking you up, and if the sun is hitting the snow, the whole landscape glows and turns golden.
Meanwhile, a windy day at +5 degrees Celsius can be awful. You will be chilled to your bones in 15 minutes. You will not want to be outside. You will look at the thermometer and think, "5 degrees, that's not bad," and then walk out the door and immediately understand your mistake.
This is why most Icelanders, when checking the weather, look at the wind speed before the temperature. Anything under 5 meters per second is considered calm; 5 to 10 meters per second is breezy but fine; 10 to 15 meters per second is becoming unpleasant. At 15 to 20, you're noticing it constantly, and at 20+, you are in proper wind territory where things start blowing around, and walking against it becomes an actual workout.
So when a local says "good weather," they almost always mean: not much wind. The temperature is secondary.
What Counts as a Good Day, Realistically
A lovely day in Iceland, the kind locals plan around, take their kids outside for, and post photos of, looks something like this: light wind, partial sun, temperatures anywhere from about 3 degrees to 15 degrees Celsius. That window covers most of spring, summer, and a chunk of fall, and any day in that range with the sun out is a day worth celebrating.
In summer, 20 degrees is considered a heatwave. The news will mention it. People will go to the pool, lie in the grass at parks, and complain about how hot it is. You will see Icelanders in shorts who have not seen their legs since last August. Twenty-five degrees is rare enough that it becomes a topic of conversation for days afterward, and most homes don't have air conditioning because what would be the point? It'll be back to 14 degrees by Thursday.
In winter, the bar shifts. A sunny, calm day at -5 degrees is good weather. A sunny, calm day at -10 is also good weather. The cold itself doesn't bother most locals as long as the wind isn't pushing it through your jacket. I've been on hikes at -12 where I had to take off my outer layer because I was getting too warm from walking. The cold without wind is a completely different beast from the cold with wind.
The other factor to consider is daylight. In the depths of winter, when the sun is up for about four hours, and even then it's barely clearing the horizon, any sunny day at all becomes "good weather" almost regardless of temperature. People will rearrange their schedules to get outside during the brief window of light. In June, when the sun never really sets, golden light bouncing off the mountains at 23:00 is some of the best weather you'll ever experience anywhere.
The Saying You'll Hear Constantly
There's a phrase you'll hear from basically every Icelander you talk to about weather, and it's the cornerstone of the local approach: "Það er ekki til vont veður, bara vondur klæðnaður." There's no such thing as bad weather, just bad clothes.
What this means in practice is that a four-year-old at preschool is going outside to play in the snow regardless of whether it's snowing right now. They'll be wearing a proper snowsuit, waterproof mittens, waterproof boots, and a hat with ear coverage, and they'll have a blast. The same kid in jeans and sneakers would be in tears in 15 minutes. The difference isn't the weather, it’s the gear.
This carries through every age. Joggers run in horizontal rain. Dog walkers walk their dogs in sleet. People bike to work in November. Kids' football practice happens in conditions that would close schools in most other countries. None of this is toughness or stubbornness; it's just the recognition that if you wait for perfect weather, you'll do nothing for 10 months a year.
A few things this looks like in actual life:
- Wool is everywhere. Not synthetic fleece, not cotton, but wool. Specifically, Icelandic wool, the lopapeysa sweaters you've seen in every souvenir shop are functional gear, not costumes. Wool stays warm when wet, which matters here because everything eventually gets wet.
- Layering is non-negotiable with a base layer, a mid-layer, and a wind shell. Add or remove as needed. Locals never wear one big coat, they wear systems.
- Waterproof everything. Boots, jacket, pack cover. The rain isn't always heavy, but it's persistent, and being slightly damp for hours is what actually wears you down.
- You stop checking the weather constantly. Once you trust your gear, you stop caring about the forecast. You just go.
What Locals Do When the Weather Is Good
When a beautiful day shows up, especially in the long summer evenings or on a calm winter morning, locals tend to do a fairly predictable set of things. None of them are surprising, they're just done with more enthusiasm than you might expect, because good weather isn't taken for granted here.
Visit a Pool
This is the big one. Every Icelandic town has at least one geothermal swimming pool, and on a good-weather day, they fill up. The pools are open year-round, in all weather, but a calm sunny day brings everyone out. People go before work, after work, on lunch breaks, and on weekends with the entire family.
The pools aren't really for swimming, or rather, swimming is just one option. The main attraction is the hot tubs where people sit in water at various temperatures (usually 38 to 42 degrees Celsius) and chat. This is where actual community happens. Local politics, neighborhood gossip, who's seeing whom, what the football team did last weekend; all of it gets discussed in the hot tubs. Tourists sometimes find this strange because Americans, for instance, tend to keep to themselves in similar settings, but in Iceland, the hot tub is a social space, and you should expect to be drawn into conversation.
In Reykjavik, the big pools are Laugardalslaug (the largest, with multiple pools, hot tubs, a slide, and a steam bath), Vesturbaejarlaug (the locals' favorite, intimate and unpretentious), and Sundhöllin (downtown, in a beautiful old building). Each town has its own, and they’re cheap.
Go for a Hike
Iceland has hiking trails for every level of ambition, and locals take full advantage when the weather cooperates. In Reykjavik, the easy go-to is hiking up Mount Esja, the flat-topped mountain you can see from the city. The standard route up to Steinn (a marker about two-thirds up) takes a couple of hours round trip, and on a clear day, you'll see the entire Reykjavik area spread out below.
For more ambitious days, people drive out to Glymur (Iceland's second-tallest waterfall, reached via a hike that involves crossing a river on a log), Mount Helgafell, or any of dozens of trails in the surrounding areas. The general approach is to check the wind forecast, pack layers and food, tell someone where you're going, and head out.
Hiking culture here is serious but not exclusive. People hike with dogs, with kids in carriers, with grandparents. It's a normal weekend activity, not an extreme sport.
Day Trips
A good-weather day is also when people leave town. The Golden Circle (Þingvellir, Geysir, Gullfoss) is a classic local day trip, or you can drive out to the south coast for waterfalls and black-sand beaches, or up to the Snæfellsnes Peninsula for a more dramatic landscape. Locals tend to leave early, pack their own food (eating out on the road in Iceland is expensive), and come back late.
In summer, when the daylight is essentially infinite, these trips can stretch into 10 or 12-hour expeditions because you can keep going until midnight and still be driving home in golden light.
Grilling, Yes, Grilling
This will sound bizarre, but Icelanders are devoted grillers. The minute the weather is even halfway cooperative. and "halfway cooperative" can include light rain. Out come the grills to cook lamb, fish, hot dogs, vegetables, and more lamb. Backyards and balconies across Reykjavik fill with smoke. There's a national affection for outdoor cooking that's completely disproportionate to the number of days that genuinely support it.
What Counts as Bad Weather
So if good weather is a fairly broad category here, what counts as actually bad weather? When do locals stay inside? The honest answer: not often, but when we do, we mean it. The weather you don't mess with in Iceland involves some combination of high winds, heavy precipitation, and limited visibility. A few specific scenarios:
Severe Wind Warnings
When the meteorological office issues a yellow, orange, or red wind warning, you pay attention. Yellow means be cautious. Orange means probably stay home if you don't have to go out. Red means do not drive, do not be outside, do not even think about it. Wind warnings are taken seriously here because in serious wind, things actually become dangerous; car doors get ripped off their hinges, roof tiles fly, and you can be physically knocked over while walking down the street.
Blizzard Conditions
Heavy snow combined with high wind creates whiteout conditions where you cannot see in front of you. Driving in this is dangerous, and the road authority will close roads, sometimes the entire ring road, sometimes specific mountain passes. When the roads close, you respect that. Tourists who try to push through closed roads end up making the news, and not in a good way.
Ice Storms and Freezing Rain
These are less common but particularly nasty. Sidewalks become skating rinks, and the local hospitals see a spike in broken wrists and ankles. On these days, even locals who would otherwise tough it out tend to stay in.
If Veðurstofa issues warnings, take them seriously. The warnings are not theatrical; they're calibrated, and Icelanders have a high baseline tolerance, so when they say it's bad, it's bad.
