After a relatively cool start to October, Brisbane is on track to experience its warmest weather since March. Heat has been building across the interior over the last week, and has been dragged over Queensland ahead of a low pressure trough. This will cause a run of hot days for the state's capital. The city climbed to 28 degrees yesterday and is predicted to reach at least 30 degrees on each day over the weekend. Sunday is looking like being the hottest day, with a forecast maximum of 32 degrees. If this eventuates, it would make it the warmest day since March, and the warmest October day since 2009 when it reached 35 degrees. Providing the next three days stay above 28 degrees, this will also be the warmest October spell for Brisbane in three years, when there were four consecutive days above 29 degrees. This will provide great beach weather in the coming days, something that has been noticeably lacking over the last two years due to persistent La Niña conditions. With neutral conditions and the likelihood of a weak El Niño developing this spring, Brisbane can look forward to more hot days than seen over the last two summers. Looking further ahead, Brisbane will see temperatures return close to average early in the new week. However, the mercury is set to rise again mid-week ahead of another trough.
