Officers said they were disappointed and urged people to stay home.
They posted on their Facebook page: "With the sun shining today we are disappointed to see more people out and about around the town, not following social distancing guidance.
"We know it is tempting when the weather is nice but please listen to Government guidance and ensure you are only leaving your home for essential trips.
"Thank you to everyone who is doing what they can to help stop the spread of the virus."
