Iceland in May: Cons
Visiting Iceland in May can be a great time to experience the country before the peak tourist season hits, but there are also some downsides to keep in mind. One major con of visiting Iceland in May is that the weather can be unpredictable, with a mix of sunshine, rain, and sometimes even snow.
This can make it difficult to plan outdoor activities or sightseeing trips, and visitors may need to be flexible and willing to adjust their plans depending on the weather. Additionally, while May is before the peak season, it is still a popular time to visit, which means that accommodations and tours may be more expensive or booked up in advance.
Another potential downside of visiting Iceland in May is that some popular tourist destinations may not be fully accessible or open for the season yet. For example, some hiking trails may still be closed due to snow or wet conditions, and some natural attractions may not be fully accessible due to road closures or maintenance.
This could limit the options for outdoor activities or sightseeing, and visitors may need to do more research to ensure that they can still visit the places they want to see. Finally, while May is a relatively mild time of year in Iceland, visitors should still be prepared for chilly temperatures and possibly even high winds or storms.
