I've been reviewing water guns for years, and these are the ones I'd recommend for the heatwave
This guide recommends several water guns suitable for hot weather, including the Hydro Frenzy, Dunk-Fill 2-Pack, Super Soaker Twin Tide, SpyraGo, and various XShot models. Many of these are currently available at discounted prices during Prime Day.
