Likely causes
Phyllosticta leaf spot
Most likelyHow to tell: You will see small, circular brown or tan spots with darker borders on the foliage. These often appear after periods of high humidity or frequent rain.
What to do: Remove and dispose of any fallen leaves around the base of the tree to stop spores from spreading. Avoid overhead watering to keep the foliage dry. If the infection is severe, apply a copper fungicide according to the label instructions during the early spring.
Sunscald
PossibleHow to tell: This is less common for this plant, and usually happens when a young tree is moved suddenly into intense, direct afternoon sun. Look for bleached or scorched patches on leaves that face the brightest light.
What to do: Provide temporary shade for the tree during the hottest part of the day using a shade cloth. Gradually acclimate the plant to more sun over 2 to 3 weeks. Ensure the soil stays moist to help the tree handle the heat.

When to worry
It is rarely fatal, but you should worry if the spots cover more than half of the leaf surface and cause premature leaf drop. Minor spotting is normal in very wet summers.
Stopping it coming back
Keep the area around the base of the tree clean of debris and ensure good air circulation between branches.
