Four distinct seasons run through the year here, from January's chill to July's warmth, with rain spread fairly evenly across the calendar rather than concentrated in one stretch. In July, expect highs around 15°C with rain on roughly 10 days of the month.
Northern Lights (Aurora Borealis) (February) — Long nights and frequent clear spells make this a strong window for aurora viewing around the island.
The Golden Circle — Þingvellir, Geysir, and Gullfoss — is an easy day trip from Reykjavik, while the South Coast adds black-sand beaches and glacier lagoons. The Blue Lagoon is touristy but genuinely relaxing, and winter visits open up Northern Lights tours and ice cave exploration.
