Near-record warmth hit the Nullarbor today, with Eucla reaching 27.4 degrees, the warmest mid-winter day this far south in four years. For anywhere in the country this far south, it hasn't been this warm in July since 2007. In that July, Eucla was the hot spot again, reaching 27.5 degrees, 10 above its long-term monthly average. Eucla's warmest July day on record is 28.3, set in 1969. For this far south, the warmest July day in the past decade was 31 degrees, also on the Nullarbor, in Eyre, in 2001. This is an indication of how rare today is. Typically in July, southerly or westerly winds would affect the Nullarbor with the occasional day of northerlies, like today. These northerlies have been building for several days now, developing last weekend, long enough to gain little bit more warmth each day. Today, with help from a deep low west of Perth, northerlies have been strong and gusty enough to bump Eucla's temperature past 27. The warmth air is courtesy of warmer than normal waters to the west of the state. The air above these waters is therefore relatively warm and has been sent across much of Western Australia ahead of cold fronts, which have not made it to Eucla.
