Hi Sarim,
I'm just across the border from you and up until now, we've had a lot of below-normal overnight temperatures this Spring.
I put my plumeria (~80+), citrus, and palm trees out the first weekend in May (and had to bring them back in when it snowed the following weekend!) Up until now, most of my plumeria have been very slow in moving from the "waking-up" stage to the "rapid-growth" stage. But with the current heatwave in progress, the growth seems to be accelerating, so your plants should probably experience the same over the next week.
John
