Data extracted in May 2024.

Planned article update: May 2025.

Highlights

Nearly one-third of tourism nights in 2023 were spent in July and August.

Strongest tourism seasonality in 2023 observed in Croatia, Greece, Bulgaria, Albania and Montenegro.

Tourism nights spent at campsites were heavily concentrated in the third quarter of 2023 (64% of the annual nights).

This article focuses on the tourist accommodation sector in the European Union (EU) Member States, candidate and EFTA countries and looks at the seasonality of arrivals and nights spent in accommodation establishments. This analysis from the point of view of the supply side complements another article on seasonality in tourism demand in which the seasonal bias in tourism trips of Europeans is discussed. The most recent monthly data on tourist accommodation can be found in the article "Tourism statistics - nights spent at tourist accommodation establishments". In the last quarter of the year, Eurostat also publishes an article on seasonality at regional level.

Arrivals and nights spent in tourist accommodation

July and August accounted for 32 % of all annual nights spent in EU tourist accommodation in 2023

Many tourist activities have always been highly seasonal. Leading reasons are environmental factors, such as climate conditions or geographical location, together with social and cultural factors, such as school holidays. During peak vacation times, tourist areas may face overcrowding and resource strain. Conversely, quieter periods can lead to underutilised facilities and job instability due to fluctuating demand. Figure 1 and Table 1 summarise the monthly data and seasonal pattern in 2023. The most popular months were August (17 % of all nights spent at EU tourist accommodation in 2023, corresponding to 482 million nights spent) and July (15 %, 438 million nights). The number of nights spent during the peak summer month was nearly four times higher than in the off-peak month January (130 million). Figure 1 shows that the seasonal pattern for nights spent was a bit more pronounced than for arrivals, with 26 % of annual arrivals recorded in July or August (both 13 %). This suggests that the length of stay is longer during these busier months, likely corresponding with many tourists' main holiday period.

Wide variety of seasonality measures

Independently of the method used, Croatia recorded the highest seasonality

A first approach is the Gini coefficient, measuring the inequality in a frequency distribution. Originally used to study income inequality, it can also be applied to tourism seasonality. A detailed discussion on the Gini coefficient is outside the scope of this article, but it basically measures the difference between the cumulative share of monthly nights spent (ranking the months from lowest to peak) and the distribution in absence of seasonality (or uniform distribution of the annual nights spent over the twelve months), as illustrated in Figure 2. The value of this seasonality measure is shown for all countries in Figure 3a and in the last column of Table 1. The discrepancy between the observed seasonality and a situation without any seasonality was more than twice as high in Croatia (0.60) compared with the EU average (0.25). High seasonality was also observed in Greece (0.49) and Bulgaria (0.40).

A second approach looks at the share of the two dominant months in the annual number of nights spent and is shown in Figure 3b and Table 2. While this measure is more intuitive for users, it can be affected by extreme values in the peak month(s). The seasonal pattern was most pronounced in Croatia (56 % of nights spent in 2023 were recorded in July and August), Bulgaria (45 %) and Greece (41 %). Meanwhile, the seasonal pattern was least pronounced in Malta (23 %) and in Germany and Finland (both 24 %).

A third approach is the seasonal deviation, defined as the average of the (absolute) deviations of the monthly data points from their annual mean. The highest seasonal deviations in 2023, as shown in Figure 3c and Table 1 (last but one column), were observed in Croatia and Greece, with 8.3 and 6.6 points respectively, the lowest seasonal deviation was observed in Finland (1.5).

Finally, one can look at the difference between the peak and low month, although this peak/low ratio can be strongly influenced by extreme values in those two months, ignoring the seasonal pattern in the remaining ten months. Table 3 shows that at EU level, the number of nights spent in the peak month (August, 482 million nights) was 3.7 times higher than in the low month (January, 130 million). For Croatia, this ratio was 44.7, while for Greece it was 19.3.

Seasonality at country level

Different seasonal impact across Europe

The overall observation that July and August are the peak months for EU tourism holds for all countries. Table 2 shows that in all countries these two summer months are dominant. In 16 EU Member States, most tourism nights were spent in August. In 10 EU Member States July was the month with the highest number of nights spent (see also Table 3). No data is available for Ireland. However, the significance of July and August was not the same in all countries. In Croatia, more than half (56 %) of all nights spent in 2023 were recorded in these two months. Also in Greece and Bulgaria, July and August accounted for more than 40 % of the annual tourism nights. In Malta, Finland, Germany, Austria and Portugal, around 1 in 4 tourism nights was observed in July or August. The different seasonal pattern in these countries is illustrated in Figure 4, showing the near-absence of tourism flows during the winter months in the highly seasonal countries (with January, February, March, November and December jointly accounting for less than 5 % of the annual nights spent in Croatia). Countries with skiing tourism, like Austria and Finland, can benefit from a second, albeit lower peak in the winter to obtain a better spread of tourism flows throughout the year.

Given the large variety of tourism destinations, even within a country, it is relevant to analyse the seasonality of tourism not only at the country level, but also at the regional level. At the time of writing of this article, monthly data at regional level for 2023 was not yet available, but for a regional analysis of seasonality, please consult the article "Tourism statistics - seasonality at regional level".


Seasonality by type of accommodation

Two-thirds of nights spent at campsites were recorded in the third quarter

In the previous sections, the tourist accommodation sector was analysed as a whole. The breakdown by type of accommodation shown in Figure 5 and Table 4 reveals that seasonal fluctuations were less prominent for hotels than for other tourist accommodation. The sharpest summer peak was registered in campsites (including recreational vehicle parks and trailer parks), which depend much more on the weather and are often closed in winter.

The third quarter, spanning the summer months July, August and September, was the peak season for all three types of accommodation considered. This was the case in all countries. The dominance of the summer quarter was, however, much stronger for the campsites, with nearly two-thirds (64 %) of all nights spent recorded during those three months, with almost non-existent tourism flows in the first and fourth quarter (respectively 3 % and 5 % of the annual nights spent). For the hotels segment, the third quarter accounted for 36 % of the nights spent in 2023, for the segment of holiday and other short-stay accommodation this was 44 %. In three EU Member States - Bulgaria, Croatia and Greece - hotels had to rely on the third quarter for more than half of their overnight stays. This was also true for Montenegro and Albania. The dependency on the third quarter was very high for campsites in Bulgaria, Czechia, Slovakia, Iceland, Montenegro and North Macedonia, with less than 1 in 5 tourism nights observed outside that quarter.

Seasonality by origin of the guest

Slightly longer summer season in the segment of international tourists

Figure 6 and Table 5 show the spread of nights spent throughout the year, separately for domestic guests and for international tourists. Although no significant differences in seasonal patterns for these two tourist flows can be observed for 2023, the August peak was a bit more pronounced for domestic tourism flows. Still, the share of the third quarter in the annual nights spent was slightly higher for the international segment (43 %) than for the domestic segment (41 %), partly due to the main seasons extending more significantly into September for international tourists (with September accounting for 11.4 % of the annual nights spent by foreigners, compared with 9.5 % for domestic tourism flows). This relatively sharper drop in September, can also be observed in Figure 5, but in general the distribution of nights spent by domestic and by international tourists broadly followed the same pattern.

In the countries identified earlier as having a strong seasonal bias in the accommodation sector, there were large differences between the spread of domestic and international guests over the four quarters of the year. For instance, in Croatia 70 % of international nights spent were recorded in the third quarter. The first and fourth quarter combined, accounted for only 6 % of the annual nights spent by international tourists in Croatia, compared with 23 % for Croatian residents travelling in Croatia.

Data sources

Regulation (EU) No 692/2011 concerning European statistics on tourism, organises the European statistical system of tourism statistics. This system consists of two main components: statistics on capacity and occupancy of tourist accommodation and statistics on tourism demand. The former are collected in most EU Member States via regular reporting by accommodation establishments, while the latter are mostly collected by means of traveller surveys at the border or via traditional household surveys. Statistics on the occupancy of tourist accommodation refer to the number of arrivals (at accommodation establishments) and the number of nights spent by residents and non-residents, broken down by type of establishment or by region. Both annual and monthly series are available. Statistics on the use of bedplaces and bedrooms (occupancy rates) are also compiled. This article is based on the monthly accommodation data. Statistics on the demand for tourism look at participation, i.e. the number of residents that make at least one trip of at least one overnight stay during the reference period. They also look at the number of tourism trips made (and the number of nights spent on those trips), broken down by tourism-related variables such as country of destination, month of departure, length of stay, type of organisation of the trip, mode of transport, type of accommodation or expenditure, and by socio-demographic variables, such as age or gender.


Context

In June 2010, the European Commission released a Communication entitled Europe, the world's No 1 tourist destination - a new political framework for tourism in Europe. One of the challenges and opportunities facing the European tourism industry is the seasonal distribution of demand for tourism. Better use of existing tourist infrastructure and staff in the low season could help businesses improve their productivity and benefit from a more stable and motivated workforce. Extending the tourism season or spreading tourism activities more evenly throughout the year can boost the sustainability and competitiveness of European tourist destinations.
