Yes, it is beautiful out yet again today, and yes, you just want to feel the breeze on your legs. The rule however is to not rush the season. Even if you have new shorts that you just can't wait to show, it's still just a bit early for the short pants unless you are running or doing some other physical activity. For the rest cotton twills are still a good bet. This isn't a popular opinion, but it's the only one I have. Be patient (and maybe do some calf exercises now so that you're ready when shorts time comes).
