Nighttime chill in highland areas

As the sun sets, the temperatures in the highland areas drop significantly, emphasizing the arrival of colder days. The mercury can easily plunge to around 32°F (0°C) or even lower during the night, especially in the latter part of the month. The weather can still be changeable — a clear day can quickly turn stormy and vice versa. When day hiking, it's essential to bring layers to combat the varying temperatures.

Daytime temperatures in Reykjavik and other places

Understanding the Icelandic weather in October

The weather in Iceland in October can be unpredictable. Make sure to read the following chapters.

Wind intensity and challenges

The winds in Iceland during October are known to increase in intensity, inching towards the Winter season wind speeds. The average hourly wind speed in Reykjavik increases from 11.3 miles per hour (18.2 km/h) at the beginning of the month to 12.5 miles per hour (20.1 km/h) by its end. If you're traveling to this Nordic island during October, prepare for average wind speeds of up to 16.8 miles per hour (27 km/h).

It’s essential to note that the wind experienced at a given location is highly subject to local topography, and the instantaneous wind speed and direction can vary more widely than these average values. Travelers may face unique challenges, such as navigating through high winds, which at their peak, can reach speeds associated with mid-winter levels in Iceland.

How to prepare for the windy weather

Layering is the most effective way to dress for the weather. Begin with warm thermal undergarments, which you can add to or remove depending on the weather changes. This strategy will keep you warm in the cold, and you can take them off as the day gets warmer.

Your outer layer should effectively protect you against the wind and rain. Opt for windproof and waterproof clothing, like jackets and pants, that can keep the chill at bay and you dry in case of sudden downpours.

Possibility of rain in coastal vs inland regions

There's a considerable chance of experiencing wet days in Iceland during October, with the probability remaining relatively constant throughout the month, around 45%. A wet day is one with at least 0.04 inches of liquid or liquid-equivalent precipitation.

Rain is generally more frequent in coastal areas than in the inland region. This is due to the moderating effect of the sea on land temperatures. Consequently, clouds and precipitation are more likely to form and occur over the coastal regions.

In Reykjavík, there is a transition in the type of precipitation experienced. The chance of a day with only rain decreases from 45% to 41% throughout October, while a day with mixed snow and rain increases from 0% to 3%.

Iceland offers an array of outdoor activities that make use of its breathtaking landscapes, with glacier hiking being one of the most popular ones. With 10% of the country being covered by glaciers, Iceland is indeed a paradise for glacial exploration. October is a favorable month for glacier hikes, as these hikes are easier due to the transition from the wet summer to the freezing winter.

Glacier tours are meticulously planned and guided by experienced guides ensuring your safety, and making it an unforgettable experience. One of the top-rated glacier hikes is the Sólheimajökull glacier hike.

Although these ventures seem adventurous, keep note that these hikes require proper hiking gear and strategy, all of which are taken care of by the tour organizers.

Horseback riding

Riding an Icelandic horse is a wonderful way to explore the ethereal landscapes. In October, the horses get a thick, fluffy coat to protect them against the harsh weather conditions, making them even more adorable. And if you're lucky, you might even catch a glimpse of whales swimming in the nearby waters, adding to the magical experience of visiting Iceland.

Only minutes away from Reykjavik, horseback riding tours take place in the lush countryside, leading you through varied landscapes of fields, rivers, and mountains. This experience bestows you with an unbeatable view of the natural beauty that Iceland holds, which is quite different from what you would witness from a car window.

Snorkeling in Silfra

One of the most unique experiences you can have in Iceland, especially in October, is snorkeling in the Silfra fissure. Located in Thingvellir National Park, Silfra is a fissure that formed between the Eurasian and North American tectonic plates. What makes snorkeling in Silfra truly unforgettable is not only the fact that you are swimming between two continents but also the crystal clear waters that provide up to 328 feet (100 meters) of visibility. The temperature is around 35.6°F (2°C) year-round, but you will be provided with suitable diving gear to keep you warm.

Can you see the Northern Lights in Iceland in October

Yes, you can! October is actually one of the best months to witness the aurora borealis (best between October and March) offering you a higher likelihood of experiencing this natural wonder. Nevertheless, it's important to note that the northern lights can still make appearances at other times of the year.

Visibility of Northern Lights in October

In Iceland, witnessing the enchanting Northern Lights, also known as the Aurora Borealis, is a topmost objective for many. October proves to be an ideal month to satisfy this curiosity.

The elusive Northern Lights become visible once the Icelandic skies are dark enough for several hours. October fits the criteria perfectly with an average of 15 hours of darkness, the skies finally getting dark enough for the lights to be visible.

These lights are weather dependent, and three conditions must be met; darkness, clear skies, and high Northern Lights activity. As October's weather is generally decent, your chances of witnessing this celestial spectacle without clouds obstructing the view significantly increase.

Tracking weather and solar activity through reliable online resources like the Icelandic Meteorological Office or websites providing Aurora Forecasts can help you gauge the most suitable nights for viewing the lights.

Best places for Northern Lights sightings

While the Northern Lights can be seen from many places across Iceland, some locations offer a better opportunity for sightings, primarily due to less light pollution.

One of your best chances to spot the Northern Lights in Reykjavik is from the area around the Grotta lighthouse. This location, despite its proximity to the city, has darker skies and a broader view of the northern horizon.

In case you wish to drive from Reykjavik, Thingvellir National Park, a UNESCO World Heritage Site, is less than an hour’s drive. Its rural location away from city lights provides ideal viewing conditions for the Northern Lights.

Heading out of Reykjavik towards the southern coast takes you to Dyrhólaey, a promontory near the village of Vik. Its relative isolation and open ocean views make it another excellent spot to catch the Aurora Borealis, and if you're lucky, you might also catch glimpses of seals, blue whales, and puffins.

The Seltjarnarnes Peninsula, about a 10-minute drive from downtown Reykjavik, allows for good viewing conditions. With little light pollution and an expanse of sea, your chances of visible aurora improve significantly.

FAQ about the weather in October

Is it safe to drive in October?

Driving in Iceland in October can be both a pleasure and a challenge, but it is one of the best ways to get around in Iceland. With fall's arrival, landscapes transform into vibrant hues of red, orange, and yellow, providing magnificent views, especially along the main Ring Road. However, weather conditions can be unpredictable.

As per research, some of the highland roads start closing down at the end of September and the beginning of October due to strong winds and, sometimes, snowfall. Therefore, daily checks on the Road.is (the official website for road conditions) are crucial.

Weather conditions may involve heavy rain, snowfall, strong winds, and dense fog. These factors increase the likelihood of slippery roads and can lead to demanding driving conditions. If you are not accustomed to driving in such conditions, particularly on the gravel tracks and unlit roads leading into the countryside, it might be safer to opt for guided tours or public transportation.
