Canandaigua Lake FAQs
When is the best time of year for swimming in Canandaigua Lake?
Mid-June through early September is the reliable swim window. Water temperatures climb into the upper 60s by late June and peak in the mid-70s during July and August. Memorial Day weekend is usually still chilly (58–62°F), and by mid-September the lake starts cooling back into the 60s.
How warm does Canandaigua Lake get in the summer?
Surface temperatures typically range from 65 to 78°F in summer, with the warmest readings in late July and early August. Shallow, sheltered coves can run a few degrees warmer than open water.
Is it safe to swim in Canandaigua Lake?
Generally yes. The lake is the drinking water source for six communities and was voted best drinking water in New York State in 2013 and 2017. The main seasonal concern is harmful algal blooms (HABs), which can appear in mid to late summer. Always check for pea soup or paint streak patterns before going in, and avoid any water that looks suspicious.
What is blue-green algae and how do I know if it’s in Canandaigua Lake?
Blue-green algae (cyanobacteria) is naturally present in the lake but can bloom in hot, calm weather, usually late summer. A bloom looks like spilled green paint, pea soup, or streaks on the water. Don’t swim, wade, or let pets in water that looks like this. Rinse off with clean water if you do make contact.
Where can I swim publicly on Canandaigua Lake?
The main public swimming spots on Canandaigua Lake are Kershaw Park at the north end, Deep Run Beach on East Lake Road, Onanda Park on the west side, and Butler Beach. All have seasonal lifeguard hours, and most charge a small fee for non-residents.
When is boating season on Canandaigua Lake?
Most people boat on Canandaigua Lake from May through mid-October. Marinas and boat launches around the lake typically open around Memorial Day and close in October.
What wind conditions are safe for boating on Canandaigua Lake?
As a general rule, sustained winds under 10 mph with gusts under 15 are ideal for boating on Canandaigua Lake. Winds of 10 to 20 mph are manageable for most powerboats but can be rough for kayaks and canoes. Sustained winds over 20 mph often produce waves above 2 feet, which is a good time to stay off the water.
Does Canandaigua Lake get rougher in certain weather?
Yes. Canandaigua Lake sits in a narrow north-south valley, so north and south winds can build bigger waves than east or west winds. Afternoon storms can also move in quickly during summer, so keep an eye on the forecast before heading out on the lake.
What’s the best time of year to visit Canandaigua Lake?
