  The thermal properties of $f_{2}(1270)$, $a_{2}(1320)$ and $K_2^*(1430)$
light tensor mesons are investigated in the framework of QCD sum rules at
finite temperature. In particular, the masses and decay constants of the light
tensor mesons are calculated taking into account the new operators appearing at
finite temperature. The numerical results show that at the point which the
temperature-dependent continuum threshold vanishes, the decay constants
decrease with amount of $(70-85)\%$ compared to their vacuum values, while the
masses diminish about $(60-72)\%$ depending on the kinds of the mesons under
consideration. The results obtained at zero temperature are in good consistency
with the experimental data as well as existing theoretical predictions.
