Typical weather, averaged over 30 years (1995–2024). Ioulis sits on a grid square that is mostly sea, where the data hold only a daily average, so the page shows one typical temperature, not a high and a low. Daylight is calculated from latitude. Charts are lightly smoothed week to week; the figures in the table are not. Source: Copernicus ERA5-Land reanalysis; cloud cover from NASA's MERRA-2 reanalysis, on a coarser grid of about 50 km. Contains modified Copernicus Climate Change Service information 2026; neither the European Commission nor ECMWF is responsible for any use of it. These are averages, not a forecast.
