We report condensation of hexagonal whispering gallery modes (WGM) at roomtemperature in ZnO microwires that embody nearly perfect polygonal whisperinggallery microresonators. The condensate regime is achieved in the UV spectralrange only at energies below the first longitudinal optical (LO) phonon replicaof the free ZnO A-exciton transition and at non-zero wave vectors. Wedemonstrate that the multimodality of the WGM system and the high population offree excitons and phonons with various momenta strongly enhance the probabilityof an interaction of quasiparticles of the cavity exciton-photon system with LOphonons. We further examine the far-field mode pattern of lasing WGM anddemonstrate their spatial coherence.
