commenced approximately ten days later than the previous year, and this slower pace persisted throughout the season. Moderate temperatures coupled with delayed winter pruning in high-risk areas helped to prevent frost damage, which had been widespread in inland regions such as Breedekloof and Worcester the previous year. In-season flooding was confined to some areas along the Olifants River. Vine growth was vigorous, and disease pressure remained relatively low, although producers still had to stay vigilant to implement timely canopy management actions. Temperate conditions

during bunch and berry development were particularly favourable for berry set. Prior to harvest, the coastal regions in particular experienced below-average temperatures (Figure OS 3) , while the eastern inland regions recorded moderate temperatures, likely due to lower rainfall. Nonetheless, irrigation water supplies remained sufficient following the abundant winter rains. During the harvest period, moderate to cool and dry conditions prevailed across most growing regions, apart from brief heat peaks in December and January. This resulted in occasional sunburn,
