Nusantara The New Capital City of Indonesia (IKN) as a new urban area will certainly change climate patterns in the area due to changes in land cover. However, previous studies have only examined climate patterns in IKN due to land cover change in the present climate. While IKN as a future sustainable city requires future climate projections to support the realization of its vision. Conventional regional climate projections often encounter various limitations in downscaling from global projection data, mainly in computational costs and the length of time period required. This research uses the Pseudo-Global-Warming (PGW) method as an alternative to avoid these limitations. The results of this study were obtained that, in the PGW IKN scenario, the temperature in the study area on average increased to reach 2.5°C in the future during the day. Wind speed showed the most significant weakening at night, which was up to 2 m/s, except during the day when there was an increase in the IKN. Changes in future temperature and wind in the IKN area in the PGW IKN scenario show the combined impact of land cover change and increased greenhouse gas emissions amplifying the effects of global warming. Even so, the results of changes due to the PGW IKN scenario compared to the PGW scenario have not shown significant changes in the future.
