The distribution of the internal magnetic fields in spin glasses at non‐zero temperatures is obtained. The fact, that the spin glass phase has a huge number of local minima and that each minimum participates in the configurational averaging of the physical quantities with its own statistical weight, is taken into account. It is shown, that the probability distribution of the exchange fields in all sites does not factorize upon the sites because of the interferentional terms belonging to different sites. Detailed calculations are carried out for the homogeneous (white) averaging and for the averaging with the canonical weight multiplier exp { s/k β }.
