wax for sw france

Hi, anyone got advice on what wax to use for sw france this time of year?
I'm off there in 2 weeks (cant wait
)
Im using zoggs cool water wax atm, but now im not so sure if itll be hard enough what with this heatwave in europe. I usually use a basecoat too.
Should i get some warm water wax as a basecoat for the cool wax? or is there something harder i can use with warm wax as a topcoat?
