If you're blessed enough to have a porch,this is the perfect time to make it a paradise to play on. Take a look at your porch and see what could use sprucing up. Sweep it,plant new flowers in those pots that have been sitting and growing weeds,add some yard decor. Get a new armless chair or two. Add solar lights. Consider this area your stage to the neighborhood.
I also suggest you get a uke stand in case you have to set your uke down for a moment or two. Get one that folds up for easy carrying. don't leave your uke in the sun,tho! (I usually porch pick once the direct sun isn't shining on my porch.)
And other outdoor essentials:sunblock,lip balm with sunscreen,sunglasses,a hat that covers your ears (I have a straw Stetson) bottled water,and if you play into the early evening, citronella candles for keeping mosquitos at bay. (have a lighter on you for the candle!)
And as you're playing outdoors,this is also the time to start memorizing tunes so you won't have to hassle songbooks and the like while outside. So get ready,and go have fun playing!
