In the summer I regularly use epoxy in ambient temperatures between 90F and 100F degrees and it definately cures faster. When epoxying raw wood, I prefer that the wood is fully at the warm temperature and the curing is done at a slightly lower temperature to avoid out-gassing and to help the epoxy soak into the wood.

The epoxy is more 'runny' at higher temperatures, so glue joints may need a little more thickening with silica or wood dust than at cooler temperatures.
