The study analyzes the relationship between climatic factors and grape production in Lanzarote between 2002 and 2010, using climatic data from the Tinajo winery and production figures from the Lanzarote DO Regulatory Council.
Four key climatic factors are identified as influencing production volume:
-
Cold weather in autumn: Buds need cold days to emerge from dormancy. In Lanzarote, the necessary levels are not reached, which can affect sprouting.
-
Wind during flowering from the previous year (N-1): Strong winds during flowering can affect flower induction and cause clusterless shoots the following year. This effect was evident in 2010 due to the winds of April 2009.
-
Rainfall volume: Water shortages can reduce berry size or cause raisin, negatively affecting production.
-
Heat waves around harvest time: Extreme heat can dehydrate grapes, causing significant volume losses, as occurred in 2009, with a 25–30% reduction.
The analysis shows how specific climatic conditions can directly or indirectly affect vineyard productivity in Lanzarote.
