This plugin has an experimental version available!

This plugin generates Thiessen polygons (a Voronoi diagram) from point data such as meteorological or irrigation stations, optionally clips them to an irrigation area boundary, and computes the area-weighted average value (e.g. area-weighted average rainfall or irrigation water requirement) based on each polygon's area. AREA_HA, AREA_PCT and WEIGHT_CONTRIB fields are added to the result layer.
