{{Climate_change
|text1=- Changes in sea surface or atmospheric temperatures can change the height of cloud bases or influence the extent of the cloud decks. Therefore be sure to site the collection nets in the middle of the most dense region of fog. If climate change causes the cloud patterns to move, the nets will need to be moved to maximise the area of greatest fog density. Coastal and upland forests in temperate and tropical regions, where fog is greatest, will be most affected. <br> - When fog collection is used for irrigation to increase forested areas or vegetation coverage, it can help to counteract the desertification process.}}
Fog collection is most suitable for locations with frequent fog periods. Upland areas where fog is produced by the advection of clouds over the terrain or where clouds are forced to rise over mountains are most suitable, in areas of prevailing winds between 3 - 12 m/s and with no obstructions to wind flow. Fog formed on the ocean surface, or nocturnal radiation fogs in low-lying areas normally lack sufficient liquid water content or sufficient wind speeds for substantial water collection. Examine meteorological records and consult local people about their observations.
