The best time to visit Lake Preston is during the summer months, from June to August, when the weather is warm and ideal for outdoor activities.During these months, the average daily temperatures range from 20°C to 28°C, making it great for enjoying the lake. You'll find plenty of opportunities for fishing, boating, and swimming. The longer daylight hours also allow for extended enjoyment of the natural surroundings.For those who enjoy fishing, late spring and early autumn can also be rewarding. May and September offer cooler temperatures, typically between 10°C and 20°C, which can be excellent for catching walleye and northern pike without the peak summer crowds. These shoulder seasons provide a more tranquil experience for anglers.
