Aphids are not the least bit fussy what time of year it is, especially in zone 9 I am so jealous I am zone5/6.
If the Maple is small enough for you to reach with a hose there are several solutions!
There is just a hard stream of plain water.
or water with horticultural oil, found at garden centers and hardware stores.
But, my favorite is to go on line, TYPE in BENEFICIAL INSECTS, or LADY BEETLES and buy lady bugs, probably a whole quart!
Then wait until dusk, or a really dreary dark day, And let them out of the container to run up the trunk of the tree, 24 hours, no fuss, no muss, no Aphids!

Hosing them off is a good approach since once they are off the plant they cannot get back on. Silly little buggers. A systemic insecticide might work too.
One thing you should NOT do is spray. Aphids have natural enemies like ladybugs. Where you have an aphid infestation you will likely have ladybug eggs laid among them. They will hatch and begin to control the aphids. When you spray you kill both the harmful and the beneficial insects - and aphids reproduce much faster than beneficials. Aphids are born pregnant!

There's an excellent product that should solve your problem. It's called "Bayer Advanced Garden Tree & Garden Insect Control". The active ingredient is "Imidacloprid" and is very easy to apply by simply mixing with water and placed onto the soil over the roots. It is then translocated up to the leaves and will control many sucking insects for up to 12 months!
"Imidacloroprid" is very safe to humans but controls sucking insects by attacking their nervous system, paralyzing them which eventually leads to their demise. There are about 20 insects that are controlled by this product....some of which include; Aphids, Thrips, Whiteflies, Scale, Borers and many more. Unfortunately, it DOES NOT control mites.
Mixing directions are clearly stated on the label. I used it to control aphids on my 15-foot flowering plum and it did an great job! I now use it on all my flowering plants as well as my ornamental trees.
GOOD LUCK!

I don't know "why the aphids in the summer", but if you just hose your maple tree down well that should knock the aphids off your tree.
