The areas in orange and red have had the most days with maximum temperatures of 28°C or above in July. These hot days can cause higher levels of flower abortion, especially if they come in combination with warm nights. Areas in light green have had 2 to 4 days with maximum temperatures of 28°C or more, and dark green areas have had fewer than 2, which would be considered good news on the heat front for those regions.
