καύσων, καύσωνος, ὁ;
1. burning heat of the sun: Mat_20:12; Luk_12:55; Jas_1:11 (others refer all these passages to the next entry); (Isa_49:10; (Gen_31:40 Alex.; cf. Jdt_8:3); Sir_18:16; Athen. 3, p. 73 b.).
2. Eurus, a very dry, hot, east wind, scorching and drying up everything; for χΘγΔιν, Job_27:21; Hos_12:1; ἄνεμος καύσων, Jer_18:17; Eze_17:10; Hos_13:15 : πνευαμ καύσων, Jon_4:8 (cf. Hos_12:1); (on this wind cf. Schleusner, Thesaurus ad Sept. iii., p. 297; Winers RWB (also BB. DD.) under the word ). Many suppose it to be referred to in Jas_1:11; yet the evils there mentioned are ascribed not to the καύσων, but to the ἥλιος.

Moulton & Milligan — Vocabulary of the Greek NT
καύσων [page 339]
This late word means burning heat in Mat_20:12 , Luk_12:55 , and probably Jas_1:11 : cf. Gen_31:40 and Athenaeus iii. p. 73 μελιλώτινοι στέφανοι πάνυ εὐώδεις καὶ καύσωνος ὥρᾳ ψυκτικώτατοι . In the LXX it is more frequent of a scorching wind, or sirocco, and Hort prefers this meaning in Jas I.c. In Dioscor. i. 21. 149 it is used as a medical term, heat in the stomach, and Survives in MGr = heat (see Kennedy Sources , p. 154).
