Abstract The finite-temperature behaviour of clusters can be quite different from that of extended systems. I will discuss thermodynamics of small Tin and Gallium clusters as seen via ab initio simulations. These clusters (Tin 10-30 atom clusters, Gallium 17 and 39 atom clusters) have shown higher than bulk melting Temperatures. I will also present some recently obtained results on Na55 and Na92. The irregularity of melting points observed in Na clusters as a function of size is still unexplained.
