Raspberry fruit often develop small white to tan spots in response to hot weather and exposure to direct sunlight. Typically one or two drupelets are white, while the others are healthy. Sunscald is most common when a long cloudy spell is followed by a hot spell while the berries are starting to turn red. Sunscald usually only affects those berries that ripen shortly after the weather warms, and berries that ripen a day or two later will be normal. Affected fruit can still be eaten.
