Planning a trip to Iceland often starts with one big question: what will the weather actually be like?
In south Iceland, the answer changes dramatically from month to month. Summer days are long and filled with light. In the winter, short days bring northern lights, epic sunrises, and dramatic sunsets. All year round, storms roll in only to clear just as quickly. Each season brings its own rhythm, its own beauty, and its own way of experiencing the landscape.
At Hotel Rangá, you’re right in the middle of it all. Set along one of Iceland’s most famous salmon rivers and surrounded by wide-open countryside, the hotel is perfect for both quiet moments and unforgettable adventures. Our team is always here to help you make the most of the conditions—whether that means booking a glacier hike, mapping out a scenic self-drive, or simply telling you when to step outside and look up.

January in Iceland
Average temperature: -1°C to 3°C
Precipitation: Moderate, often snow or sleet
January in Iceland is deep winter. Days are short, the air is crisp, and the landscape feels still and dramatic. Snow frequently dusts the fields, mountains, and lava formations, creating a dramatic backdrop for winter adventures.
The long nights make January one of the best months of the year for both northern lights viewing and stargazing. With very little light pollution around Hotel Rangá, clear evenings reveal countless stars, bright constellations, and sometimes even the Milky Way stretching across the sky. Guests can also visit our observatory, where guided stargazing sessions offer an even closer look at the wonders above.
January in Iceland is perfect for slow travel. Our reception team can help arrange guided excursions or suggest self-drive routes tailored to the weather conditions during your stay. Think south coast waterfalls framed in ice, black sand beaches under moody skies, or a super jeep tour into the highlands. After a day out, there’s nothing better than slipping into Hotel Rangá’s outdoor hot tubs or settling into the upstairs lounge with a hot drink.
What to wear: Warm layers, insulated waterproof jacket, boots with good grip, hat and gloves.

We still experience winter conditions, but the days have more light for more daytime adventures.
Snowy, stormy conditions are always possible; however, we like to think that the precipitation only adds to the adventure. Activities like snowmobiling, ice cave tours, and glacier hikes are at their peak. Our reception team can arrange everything for you, or help you plan a relaxed self-drive along Iceland’s beautiful south coast. Evenings often end at Rangá Restaurant, where local ingredients and seasonal dishes bring a sense of comfort after a cold day outside.
