This is based on my experience from landscaping in New Orleans since 1994:

Tropical plants need a soil temperature of 70F or higher to grow actively (24 hours).

Below 70F they slow down, with the cooler the temp the less growing obviously. One could call that partially active.

Topical plants essentially stop growing when the soil temp gets below 54F. This is generally called inactive. They will respond to heat waves accordingly as the ground will warm up but growth is very little to none at these temperatures: one might get one frond a month from a banana.

So right now the best way to guess at what temp the soil is is to check how warm your tap water is. Unless you have a thermometer you can actually put in the ground that goes down about 2 feet.
