Eyre in the Eucla set a new mark for the coldest temperature ever recorded in Western Australia, minus 7.2 degrees. The previous record was also set in August, in 1970 and that was minus 6.1 degrees at Salmon Gums. Eyre's record low temperature was due to cold southerly winds progressively turning southeasterly and drying out, allowing cloud to clear overnight and any warmth to escape. Eyre has averaged minimum temperatures of minus five degrees during the last five days, 11 below the August average. Cloudier and windier weather will return to southern WA on Tuesday and Wednesday making night's a little warmer and more bearable.
