It tends to be cloudy in Neerim Junction much of the time. The average daily solar exposure ranges from 5.9 MJ/m2 in June to 23.3 MJ/m2 in January. The average number of clear days ranges from 0.3 days in June to 4.4 days in January. The mean number of cloudy days is highest in July, with 25.4 days. The mean daily evaporation is 2.9 mm.
The sunlight data for Neerim Junction provides valuable insights for regenerating an old farm into a permaculture farm, specifically for the context of Mistwood.
The mean daily solar exposure ranges from 5.9 MJ/m2 in June to 23.3 MJ/m2 in January. This indicates that the farm receives a significant amount of sunlight throughout the year, which is essential for plant growth and photosynthesis. The higher solar exposure in January suggests optimal crop cultivation conditions and maximising summer productivity.
The mean number of clear days ranges from 0.3 days in June to 4.4 days in January. Clear days are important as they provide uninterrupted sunlight for plants to thrive. January has the highest number of clear days, indicating extended periods of unobstructed sunlight, which can be advantageous for the growth and development of crops in Mistwood.
On the other hand, the mean number of cloudy days is highest in July, with 25.4 days. Cloudy days can reduce the amount of sunlight reaching the farm, potentially impacting plant growth and productivity. Strategies to mitigate the effects of cloudy days, such as selecting crop varieties that tolerate lower light conditions or implementing greenhouse structures for controlled environments, should be considered.
The mean daily evaporation of 2.9 mm can be considered relatively low. This value represents the average amount of water that evaporates from the farm's surfaces on a daily basis.
This lower evaporation rate can also contribute to the farm's overall water balance. It means that a significant portion of the available water is retained within the soil and can be utilised by plants, supporting their growth and the regeneration of the land.
While the mean daily evaporation of 2.9 mm may be considered relatively low, it presents an opportunity to optimise water usage, enhance water conservation efforts, and create a sustainable and regenerative farming system at Mistwood.
Overall, the sunlight data suggests Neerim Junction provides favourable conditions for regenerating an old farm into a permaculture farm. The abundant sunlight, particularly during the summer months, offers opportunities for maximising crop production and creating a thriving ecosystem. However, cloudy days highlight the need for appropriate planning and management to optimise sunlight exposure for plant growth and overall farm productivity.

Insights and Implications—Varying sunlight across the year requires strategic crop planning and adaptive greenhouse use.
The variation in sunlight exposure throughout the year, with a peak in January, suggests that crop and plantation planning should be aligned with sunlight availability to enhance photosynthesis and growth rates.
The high number of cloudy days, especially in July, may impact photosensitive crops, suggesting a need for adaptive strategies such as using greenhouses or selecting shade-tolerant plant varieties.
Actions—Consider matching crops with sunlight patterns, install greenhouses, and adjust irrigation based on detailed sunlight and evaporation data.
Install greenhouses to shield crops during cloudy seasons, ensuring steady growth despite reduced sunlight in mid-year.
Capture abundant solar energy during peak months using solar panels to reduce energy costs and increase sustainability.
