Note:

WEI+ illustrates the percentage of water consumption against renewable freshwater resources available for a given territory and period.
This figure gives an overview of the worst seasonal water scarcity conditions (maximum seasonal WEI+) in any quarter of 2019 across countries in Europe. Seasonal WEI+ values are estimated as quarterly averages per country. Worst quarter of the year for water scarcity conditions is provided in brackets next to the name of the country.
Annual quarters are: Q1 (January-March), Q2 (April-June), Q3 (July-September), Q4 (October-December)

Hungary:
In contrast to the seasonal (which is correct quarterly) breakdown presented here, the division that really fits the seasons could also be used and would be representative: Q1: winter (December-January-February) Q2: spring (March-April-May) etc.
A possible division into summer and winter semesters could also be used.
Since we are talking about water resources, it would also be possible to divide them according to the hydrological cycle, in which case Q4 could start from November.

  Thank you for your comment and proposal. As most of the FW-related data are reported under fiscal year range (January-December) by the national statistical institutions, we had to adjust our datasets accordingly for quarterly / annual temporal resolutions presenting the WEI+

Hungary:
The text covers the generation of quarterly data in only one sentence, but the calculation tables are available on the main page.
Looking at the table entitled Quaterly WEI at country level (2022-07-04_WEI plus CTY seasonal v10), in the case of Hungary in 2019, it is not clear on what basis the total annual water withdrawal volume was distributed to the quarterly values. The table shows that there are more water withdrawals in Q1 and Q4 than in Q2 and Q3. Hungary only provides annual water withdrawal data, but in all likelihood, the larger water withdrawals occur in the Q2 and Q3 periods rather than in Q1 and Q4.

  Thank you for your comment, we will re-assess the Hungarian case for balanced seasonality of the WEI+
