Ahead of some more hot and humid weather this week, area beaches have been cleared for swimming.
The beaches at Grand Bend (North and South), Bright's Grove (including Mike Weir Park) and Canatara Park are monitored daily, Monday to Friday, using predictive models.
Pinery Provincial Park and Ipperwash Main Beach are monitored weekly, through water sampling and lab analysis.
While no sampling occurs along the St. Clair River, caution signs advising high bacterial levels following heavy rainfall are permanently posted at Branton Cundick Park, Brander Park, and Seager Park.
Lambton Public Health said on Wednesday morning no warning signs had been posted.
Environment Canada was forecasting a high of 30 Celsius on Wednesday and a high of 33 Celsius on Thursday. Humidex values of between 35 to 41 Celsius were also expected.
Following heavy rainfall, the water at area beaches may be temporarily polluted for up to 48 hours.
Three area beaches were posted as unsafe for swimming after last Wednesday's heavy rainfall and thunderstorms.
