Weather details in september
The month of September marks the end of summer in Iceland. The weather begins to cool and depending on the location of each locality, the climate is characterized either by the abrupt decrease in temperature as in the case of Akureyri, or by a strong increase in the intensity and frequency of rain - as for Reykjavik. Still, the climate throughout September in Iceland again becomes unfavorable.
Spetember in Reykjavik and South-western Iceland
Reykjavik's climatic conditions are influenced by marine currents and sea breezes. As a result, the city receives more precipitation compared to other localities in Iceland. With dozens of rainy days, prepare for a weather in Iceland throughout September that is very rainy. Moreover, along with the month of January, these months are among the wettest of the year. The drop in temperatures does not help the situation.
September in Akureyri and Northern Iceland
Colder but less rainy, the city of Akureyri is experiencing unpleasant climatic conditions. Temperatures are falling faster than those of other Icelandic communities. Morning temperatures are already around 4° C and we must cover with warm clothes in order to feel comfortable - especially towards the end of the month.
