Geology
{{Main|Ireviken event}}
The Ireviken event was the first of three relatively minor extinction events (the Ireviken, Mulde, and Lau events) during the Silurian period. The event is best recorded at Ireviken, Gotland, where over 50% of trilobite species became extinct.
Beach and nature

The bay is framed by high cliffs and the beach is also considered one of Gotland's best beaches.{{cite book |isbn=978-91-29-44939-6|title=Gotlands sällsamheter: Sagor och sannsagor från gutarnas ö|last1=Söderberg|first1=Bengt G.|year=1975}}
In the middle is a long sandy beach which is one of Gotland's most visited. The river Ireån opens into the bay.{{cite web |url=https://www.lansstyrelsen.se/gotland/besok-och-upptack/naturreservat/irean.html|title=Ireån}}
Formerly a fishing village, Irevik is mainly a summer cottage area, and nearly 200 cottages are on mature forest sites. The houses have been built for a long time, and the area therefore has a mixed character without a hint of mass-produced cottage area. Although the area is not very large, there are three different entertainment establishments – the Ihrebaden, Ihre farm and Ihre mill.
In the northern part of Irevik lies Sigsarve beach. It is also the starting point of the 28-square-kilometer Hall-Hangvar Nature Reserve, which is Gotland's largest. From Sigsarve beach, the reserve stretches along a {{convert|25|km|mi|abbr=on}} stretch of coastline. In the eastern part of the reserve, on the other side of the road, is Träskmyr moor, the largest preserved moor on Gotland.{{cite web |url=https://www.lansstyrelsen.se/gotland/besok-och-upptack/naturreservat/traskmyr-och-vastean.html|title=Träskmyr och Vasteån}} It is a so-called agmyr (Swedish for a calcareous bog. There are many unusual flowers in the reserve, such as the Fumana or needle sunrose (Fumana procumbens), Euphrasia and alpine key.
Climate
{{Main|Visby}}
According to the Köppen climate classification, Irevik has an oceanic climate. This renders cooler summers and milder winters than most of mainland Sweden. However, in spite of its marine position the climate is very much influenced by continental airflows. The precipitation amount is quite moderated, especially for an oceanic climate, but is relatively consistent throughout the year.
