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.
September weather is decidedly autumnal in this region, with average daytime temperatures in the low to mid-60s and evenings in the 50s or mid-40s. Even in the Baltic region, whose northern latitude suggests early snows and low temperatures, September temperatures remain in the low 60s.
