Cool or cold?

While in Sweden we experienced typical Sweden Summer weather, cloudy, cool, windy, overcast, light rain, sun, clouds, warm, light rain - all within a few short hours. However, it is summer and summer means swimming and the weather did not stop Lukas and Noah. They along with their cousins swam several times each day, sometimes jumping off the dock since there is no return... whereas wading in, allows any sane person to return to shore when the temperature is 58 degrees at the most.
