Is July a good time to visit Iceland?
Yes, if you want the whole country open and you accept peak prices. July is the warmest month at an average high of 14.9C, the second driest at around 10 wet days, and the only month alongside August when every highland road is reliably passable. You pay for it: 87.8 percent occupancy and 302,057 departures put it second only to August.
July is the month when Iceland is fully open. The last of the F-roads clear, so the interior, Landmannalaugar and Sprengisandur are all reachable. Every boat season is running, the puffins are still on the cliffs, and the weather is the warmest and second driest of the year. If your trip depends on reaching somewhere specific rather than on seeing something seasonal, July is the safest month to book.
It is genuinely the warmest month, which surprises people who assume that is August. Icelandic Met Office 1991 to 2020 averages give July an average daily high of 14.9C and an overnight low of 9.1C, against 14.1C and 8.6C in August. It is a small margin, but July holds it on both figures. Rainfall runs at 10.3 wet days and 49.9mm, second only to June.
The light is still enormous but it is now visibly shortening. There are 21 hours 4 minutes of daylight on 1 July, 19 hours 54 minutes mid-month and 18 hours 12 minutes by the 31st, so you lose almost three hours across the month. It stays bright enough at night that aurora hunting is still impossible, and the published season does not reopen until 1 September.
The real cost is not the weather, it is the crowding. Statistics Iceland put national hotel occupancy at 87.8 percent for July, and Icelandic Tourist Board figures record 302,057 departing passengers. Reykjavik summer room rates run roughly 25 to 35 percent above shoulder season. If those numbers matter more to you than reaching the interior, June gives you better rainfall and 10 points less occupancy.
Iceland weather in July
July is the warmest month in Reykjavik, with an average high of 14.9C against a low of 9.1C, and the second driest at around 10 wet days and 49.9mm. Daylight falls across the month from 21 hours 4 minutes on the 1st to 18 hours 12 minutes on the 31st, averaging 19 hours 54 minutes mid-month.
| Measure | Reykjavik in July |
|---|---|
| Average daily high | 14.9C |
| Average daily low | 9.1C |
| Wet days | 10 days. The warmest month and the second driest, around 10 wet days |
| Daylight, mid-month | 19h 54m |
| Daylight range across the month | about 21h 04m on the 1st to about 18h 12m on the last day |
Climate figures for Reykjavik from climatestotravel.com; daylight from worlddata.info, cross-checked against Icelandic operator daylight tables. Rainfall is given as wet days rather than millimetres because published Reykjavik rainfall totals differ materially between sources, from roughly 870mm to over 1,400mm a year. The monthly shape is reliable, the absolute total is not.
An average high of 14.9C is the warmest figure in the Icelandic year, and it is still not warm by most visitors’ standards. It is fleece and shell weather rather than t-shirt weather, and on an open boat at speed it feels far colder than the number suggests. The overnight average of 9.1C is the mildest of the year, which makes July the most comfortable month for camping and for late evening departures.
Ten wet days and 49.9mm make July the second driest month after June on both measures, using Icelandic Met Office records for Reykjavik station 1 across the 1991 to 2020 standard period. As everywhere in Iceland, frequency is the more useful measure than volume, because published totals disagree between sources while the frequency ranking is stable.
Daylight is the one thing that is worse in July than in June, and it goes quickly. You start the month with 21 hours and end it with 18, losing almost three hours. That is still enough for any itinerary, but by the end of July there is a real dusk again, which there is not in mid-June.
Crowds, prices and what to book ahead
July is the second busiest month of the year. Icelandic Tourist Board figures put Keflavik departures at 302,057, behind only August’s 312,964, and Statistics Iceland put hotel occupancy at 87.8 percent against August’s 89.8. Expect summer rates roughly 25 to 35 percent above shoulder season.
| Measure | July | Busiest month (August) | Quietest month (December) |
|---|---|---|---|
| Keflavik departures, 2025 | 302,057 | 312,964 | 120,016 |
| Hotel room occupancy, 2025 | 87.8% | 89.8% | 45.3% |
| Share of the 2025 total | 13.3% | 13.8% | 5.3% |
Visitor figures are departing passengers through Keflavik International Airport for the full year 2025, published by the Icelandic Tourist Board, total 2,267,638. Roughly 99 percent of visitors arrive and leave through Keflavik. Hotel room occupancy is Statistics Iceland table SAM01104, whole of Iceland, 2025.
There is very little slack in the system in July. At 87.8 percent national occupancy, accommodation outside Reykjavik books out well ahead, and the South Coast is the tightest corridor in the country because every itinerary runs along it. Book beds before you book tours: day tours from Reykjavik are far easier to get at short notice than a room in Vik.
The gap between July and June is worth doing the arithmetic on. June carries 233,802 departures and 79.7 percent occupancy against July’s 302,057 and 87.8 percent, and June has better rainfall figures on both measures. What July buys you for that premium is the interior: the last F-roads only open in early July, so a Sprengisandur or Landmannalaugar plan is genuinely safer here.
Genuine scarcity in July sits in the same places as the rest of summer. Highland huts go 9 to 12 months ahead and multi-day treks 3 to 6 months. Popular timed entries, notably the Blue Lagoon, should be booked as soon as your dates are fixed, because the slots that sell out first are the ones that fit an airport transfer.
The best tours in Iceland in July
These ten are ranked for July. Whale watching sits at the top because July is the peak of the season, the long day trips rank high on 19 hours of daylight, and the puffin trips stay strong until the colonies start leaving around 20 August. There is no northern lights tour on this list because the season does not reopen until 1 September.

Events and festivals in July 2027
July has no public holidays in Iceland, which is unusual for a peak month. The calendar milestone that matters sits just after it: Commerce Day weekend, the biggest domestic travel weekend of the year, falls on Monday 2 August 2027.
| Event | Dates | Where | Cost |
|---|---|---|---|
| No public holidays | All month | Nationwide | Shops, services and tours run on normal hours all month |
| Whale season at its peak | All month | Faxafloi Bay, from Reykjavik old harbour | Tours from €85 |
| Puffin colonies still occupied | All month, published season 20 April to 20 August | Puffin islands off Reykjavik, from the old harbour | Tours from €55 |
| Commerce Day weekend (Verslunarmannahelgi), just after July | Monday 2 August 2027, the first Monday in August | Nationwide, festivals in the Westman Islands and around the country | Free to attend, accommodation prices spike nationwide |
July is the only peak month with no public holiday in it, which is good news for a visitor. Nothing closes, opening hours are normal all month, and there is no single day where transport and services drop to a Sunday service.
The date worth knowing is the one immediately after. Commerce Day weekend, the first weekend in August, is the biggest domestic travel weekend in Iceland, and in 2027 the Monday falls on 2 August. If your trip runs to the end of July, be aware that accommodation prices and road traffic climb sharply over that final weekend as the whole country moves at once.
The rest of the July calendar is seasonal rather than scheduled. Both boat seasons are at or near their peak, the interior is open, and the daylight is long enough that nothing has to be squeezed. It is the least constrained month in the Icelandic year.
We only list dates we can stand behind. Where a date follows a rule rather than a fixed day of the month, the rule is shown alongside it. Anything we could not verify is left off rather than guessed.
What is closed or not bookable in July
Almost nothing, which is the point of July. The northern lights are impossible because the published season runs 1 September to 15 April, and the natural ice caves are a winter product. Every road is open, including the last of the F-roads, and every boat season is running.
Northern lights tours
Not running. The published aurora season is 1 September to 15 April, and in July the Reykjavik sky does not get dark enough for the lights to be visible at any point in the night. This is astronomy rather than luck, and it applies to the whole country regardless of solar activity.
Natural ice caves
The natural ice caves under Vatnajokull are a November to March product, with some operators stretching into October and April in good years. The only natural cave open year-round is the Katla cave under Myrdalsjokull. We do not currently sell an ice cave tour of any kind. The bookable ice experiences on this site in July are a guided glacier hike on a lowland tongue and Perlan’s man-made ice cave exhibit.
Nothing else
July is the most open month in the Icelandic year. The last F-roads clear in the first week: on 2026 actual dates F261 opened on 5 July and F26 Sprengisandur on 6 July, joining the June openings of F35 Kjolur and F208. Every boat season is running and every road tour operates. If your itinerary has a piece that only works when the whole country is passable, July is when to do it.
Tours on this site that are out of season in July
- Northern Lights Bus Tour with Hot Cocoa: Not running. The published aurora season is 1 September to 15 April and the July sky is far too bright.
What to wear and pack for Iceland in July
Pack for 15C and wind, not for a Mediterranean summer. The warmest month still needs a waterproof windproof shell and a mid-layer, and the lagoons and boat decks need the same kit they need in every other month.
- Waterproof and windproof shell jacket with a hood
- Warm mid-layer, even in the warmest month at 14.9C
- Waterproof over-trousers for boat decks and waterfall spray
- Walking boots with grip for wet rock and glacier approaches
- Warm hat and gloves for the sea, which stays cold in every month
- Sleep mask, there are still 18 to 21 hours of daylight
- Sunglasses and sun cream, the sun is up for 20 hours
- Swimwear and flip-flops for the lagoons
- Binoculars for the whales and the puffin cliffs
How we chose these tours
Every tour on this page was scored for how relevant it genuinely is in July, then sorted by that score, then by verified GetYourGuide rating, then by verified review count. Anything out of season is excluded and named above rather than quietly left off.
Most month pages are a tour list with a date bolted on, which means the same ten tours appear for every month of the year. That is not useful. Our default site ordering is rating then review count, and both are static, so on that basis every month would produce an identical top ten. So each tour carries a separate seasonal relevance score for each month, from 6 for the single experience that defines the month down to 0 for anything genuinely out of season, and that score sorts the list first.
Two consequences are worth stating plainly. First, the northern lights bus tour is the lowest rated tour on this site at 4.3 stars from 14,846 reviews. From November to March it is ranked first anyway, because in those months it is the reason people come and a top ten that buried it would be dishonest. Second, we do not rank on live GetYourGuide availability. Availability calendars reflect rolling booking windows rather than seasons, so a tour that is genuinely bookable next spring can look unavailable today. Season comes from published operator seasons, not from a booking widget.
Prices, ratings, review counts, titles and durations were verified one by one against the live GetYourGuide listing for each product on 28 July 2026. We do not publish a rating or a review count we have not checked, and we do not publish a date, a season or a closure we cannot source. Where the honest answer is that we do not sell something, such as a natural ice cave tour, we say so and point you at what does exist instead.
We earn a commission if you book through the links on this page, at no extra cost to you. That does not change the ranking. The tour ranked first in July is not the most expensive one on the list.
