In Semaphore and, more broadly, across South Australia: The evening will be characterized by a mix of sun and clouds, with temperatures remaining cool around 16 degrees Celsius. Light westward winds are expected, with a maximum speed of 4 km/h and gusts reaching up to 7 km/h. No rain is anticipated during the upcoming hours, so conditions will be dry. The gentle breeze and partly cloudy skies should make for a relatively calm evening. Temperatures are likely to stay steady overnight, providing a cool but comfortable night for most.
