Got Stirling's Peppercorn Lime in the mail. Great stuff. Might shoot for the Soap Commander Respect next. I like what people say about SC's makers. Sounds like a good operation.
Stirling Lemongrass & Cajeput is fantastic, but is discontinued, I think. Stirling Gin & Tonic, as others have said. Tiki Set Sail Barrister & Mann's lavender is another hot weather favorite of mine, and just way released in his great-but-inexpensive Latha soap base.
Cold River Soap Works has their Summer LE out. Also from their regular offerings, Citrus and Puro Fresco are excellent summer scents.
Ok, I have to add a soap that has grown on me and has become one of my favorite soaps period especially for summertime...................... Caties Bubbles - Waterlyptus
