October Weather in Iceland:
Average Temperature, Rainfall, Sunshine and Humidity
The tables below list the normal October temperatures and precipitation for places in Iceland. There's also information on this month's averages for sun, fog and humidity.
All the climate measures are averages of data collected at weather stations from 1991 to 2020, except for humidity which covers 1961 to 1990.
The weather information takes in all the coasts of Iceland and a few places in between. Capital city Reykjavík is in southwest Iceland. Also on the west coast, Stykkisholmur lies north of Reykjavík, while Keflavik is to the west.
Along Iceland's north coast is the town of Akureyri and farther north the Saudanesviti lighthouse. Dalatangi sits on the outer edge of Iceland's east coast. In the highlands between those two places is Grimsstadir.
Southern Iceland is where you'll find Reynisfjara Beach as well as Reykholt, an inland farming area near Thingvellir National Park.
