This is when the countryside delivers everything that makes Mongolia special: wide-open grassland, ger stays under huge skies, horse trekking in Terelj, wild horses at Hustai, and clear nights with visible stars. Rain picks up from June (summer is the wet season here), usually as short afternoon showers rather than all-day gloom, so a light rain jacket covers you.
