I’m seeing this question a lot. Yes!
Signs point to: it is safe to go outdoors. There is not virus floating freely around in the air outside.
Please do enjoy the (Norther Hemisphere) spring weather by going on walks, hikes, bike rides, etc. Dust off those roller skates or your fishing pole. Take a book or a picnic to a park. Your risk of catching COVID-19 (or transmitting it, if you are unknowingly infected) is very low in a normal low-crowd outdoor situation.
Avoid congregating and watch out for high-touch surfaces. I can’t recommend playground equipment right now, but if you insist then it should be used with extreme hand hygiene. People who like to lick the equipment and/or pick their noses while playing need to avoid it completely (typically young children, but I’m not here to judge).
Just in case you are unknowingly infected, wash your hands before you go out, and just in case, wash them immediately upon returning home.
