Peak season
Iceland in August: Weather, Events and the Best Tours
August is the best month for daylight and boat trips, and the busiest month Iceland has ever recorded. A total solar eclipse crosses Reykjavik on Wednesday 12 August 2026. Expect highs around 14.2C, roughly 16 hours 31 minutes of daylight mid-month, puffins until about 20 August and whale watching at its peak.

Is August a good time to visit Iceland?
Yes, if you want the widest choice and can live with company. August 2025 saw 312,964 departures through Keflavik, Iceland’s busiest month on record, and hotel occupancy hit 89.8 percent. Every road is open, the puffins are still on the cliffs and the sea is calm enough for small boats.
August is the one month where nothing is shut. The highland F-roads are open, the coastal and lowland glacier tongues are at their most accessible, whale watching is at its seasonal peak and the puffin colonies are still occupied for the first two thirds of the month. If your trip has to include boats, birds or the interior, this is your month and there is no close second.
The 2026 edition carries something no other August will. A total solar eclipse crosses Iceland on Wednesday 12 August 2026, with totality falling between 17:43 and 17:50 local time and the path of totality running over the Westfjords, Snaefellsnes, Reykjavik and the Reykjanes peninsula. It is Iceland’s first total eclipse since 1954. Accommodation and hire cars inside the path were already heavily booked well before the summer, so if you have not secured a bed and a vehicle for the nights around 12 August, treat that as the first thing you fix and the tours as the second.
The price of all this is crowds and cost. Reykjavik summer room rates run roughly 25 to 35 percent above shoulder season, popular departures fill days rather than weeks ahead, and the honeypot stops on the Golden Circle and South Coast are busy from mid-morning to late afternoon. The fix is simple and free: take an afternoon or early departure rather than the 08:30 coach wave.
One thing August cannot give you is the aurora. The published northern lights season runs from 1 September to 15 April, and through most of August the sky in Reykjavik never gets dark enough for the lights to be visible even when the solar activity is there. If seeing the aurora is the point of your trip, book September at the earliest.
Iceland weather in August
August in Reykjavik averages a high of 14.2C and a low of 8.6C with around 12 wet days. Daylight is the headline number: roughly 16 hours 31 minutes in the middle of the month, sliding from about 18 hours on 1 August to about 14 and a half hours by the 31st.
| Measure | Reykjavik in August |
|---|---|
| Average daily high | 14.2C |
| Average daily low | 8.6C |
| Wet days | 12 days. Moderately wet, roughly 12 wet days, drier than September but wetter than May |
| Daylight, mid-month | 16h 31m |
| Daylight range across the month | about 18h on the 1st to about 14h 30m 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.
August is Iceland’s warmest month alongside July, but warm is relative. A 14C high with wind and drizzle feels like single figures on an open boat deck or at the base of Skogafoss, and the coastal wind is what people underestimate. Waterproof shell, warm mid-layer, and a hat that will not blow off: that combination works on every day tour on this list.
The daylight collapse across August is the stat that actually changes your planning. You lose roughly three and a half hours of daylight over the 31 days. Early in the month the sky barely gets properly dark at all, which is why aurora tours are not running. By the very end of the month the nights are returning and the lights become possible again.
Rain in Iceland is best planned for as frequency rather than volume. Published Reykjavik rainfall totals vary widely between sources, so we quote wet days rather than pretending to a millimetre figure we cannot stand behind. Twelve wet days in August means most trips will get rained on at some point and almost none will be rained out.
Crowds, prices and what to book ahead
August is the most crowded and most expensive month of the year. Keflavik handled 312,964 departing passengers in August 2025 against 120,016 in December, and national hotel occupancy reached 89.8 percent, rising to 93.1 percent in South Iceland where the glacier and waterfall tours run.
| Measure | August | Busiest month (August) | Quietest month (December) |
|---|---|---|---|
| Keflavik departures, 2025 | 312,964 | 312,964 | 120,016 |
| Hotel room occupancy, 2025 | 89.8% | 89.8% | 45.3% |
| Share of the 2025 total | 13.8% | 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.
The Icelandic Tourist Board’s Keflavik departure counts put August 2025 at 312,964, the single biggest month in the series and 2.6 times December’s 120,016. Statistics Iceland’s hotel occupancy table SAM01104 tells the same story from the supply side: 89.8 percent nationally for August, and 93.1 percent in South Iceland. At those numbers there is very little slack in the system, which is why last-minute accommodation in August is both scarce and expensive.
What that does and does not mean for booking is worth being precise about, because most travel sites overstate it. Day tours from Reykjavik in August do fill, and popular Golden Circle and South Coast departures can sell out several days ahead in the second and third weeks. But the products that genuinely sell out months in advance in Iceland are highland huts, which go 9 to 12 months ahead, and multi-day treks at 3 to 6 months. A Golden Circle seat is not in that category.
The 2026 eclipse changes the maths for one week only. Beds and hire cars inside the path of totality around 12 August have been going since long before the season started. Tours themselves are less exposed, but transport and accommodation on 11 and 12 August are.
The best tours in Iceland in August
These ten are ranked for August specifically, not for the year. Puffin and whale trips make the list because both seasons are open at once, and the long days make the 10 and 11 hour South Coast and glacier tours comfortable rather than a race against the light. Northern lights tours are absent because the season has not opened.

Events and festivals in August 2026
August 2026 has one genuinely once-in-a-lifetime date. A total solar eclipse crosses Reykjavik on Wednesday 12 August with totality between 17:43 and 17:50 local time, Iceland’s first since 1954. Culture Night and the Reykjavik Marathon fall together on Saturday 22 August.
| Event | Dates | Where | Cost |
|---|---|---|---|
| Total solar eclipse | Wednesday 12 August 2026, totality 17:43 to 17:50 local time | Path of totality crosses the Westfjords, Snaefellsnes, Reykjavik and Reykjanes | Free to watch |
| Reykjavik Culture Night (Menningarnott) | Saturday 22 August 2026 | Central Reykjavik | Free |
| Reykjavik Marathon | Saturday 22 August 2026 | Central Reykjavik, same day as Culture Night | Free to watch, entry fee to run |
The eclipse is the reason 12 August 2026 will be the single most contested night of accommodation in modern Icelandic tourism. Totality is short, the weather is Icelandic, and the path is wide enough that Reykjavik itself is inside it. Two practical points: bring certified eclipse glasses meeting the ISO 12312-2 standard, because you cannot buy them everywhere at short notice, and plan to be mobile, because cloud cover on the day is the only variable that matters and the path is long enough to drive along.
Culture Night is worth building a Saturday around. The city closes streets, opens studios and homes, and runs free events into the evening, and the marathon runs the same morning. The date follows a rule rather than an ordinal position in the month: it is the Saturday on or after 18 August, which in 2026 falls on Saturday 22 August.
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 August
Very little. August is the month with the fewest closures in the Icelandic year. The one real gap is the aurora: the published northern lights season runs 1 September to 15 April, so lights tours are not operating. Puffins also leave around 20 August.
Northern lights tours
Not running for most of August. The published aurora season is 1 September to 15 April. In early and mid August the Reykjavik sky never gets dark enough for the lights to be seen, however strong the solar activity is. This is not a matter of luck, it is astronomy.
Puffins, from roughly 20 August
The published puffin season runs 20 April to 20 August. Book a puffin trip in the first three weeks of the month. By the end of August the birds are leaving and by mid-September the cliffs are empty.
Natural ice caves
The natural ice caves under Vatnajokull are a November to March product, with some operators extending 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 August are a guided glacier hike on a lowland tongue and Perlan’s man-made ice cave exhibit.
Nothing else
The highland F-roads are open in August, the interior routes are passable, every boat season is running and every road tour operates. If your itinerary has a piece that only works in summer, August is when to do it.
Tours on this site that are out of season in August
- Northern Lights Bus Tour with Hot Cocoa: Not in season. The published aurora season opens on 1 September.
What to wear and pack for Iceland in August
Pack for 14C with wind and rain rather than for a European summer. A waterproof shell, a warm mid-layer and proper walking shoes cover every tour on this page. Add swimwear for the lagoons and a sleep mask, because it barely gets dark.
- Waterproof and windproof shell jacket, hood attached
- Warm mid-layer such as fleece or light down
- Waterproof over-trousers for boat decks and waterfall spray
- Walking shoes with grip for wet rock at Seljalandsfoss and Reynisfjara
- Hat and a buff, the wind on an open RIB is the coldest part of an August day
- Swimwear and flip-flops for Sky Lagoon or the Blue Lagoon
- Sleep mask, because early August nights barely darken
- Certified eclipse glasses meeting ISO 12312-2 if you are here for 12 August
- Sunglasses and a small daypack
How we chose these tours
Every tour on this page was scored for how relevant it genuinely is in August, 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 August is not the most expensive one on the list.
