All of these regions have a low chance of rain (ie, less than 10%). The risk of rain comes from afternoon cloud build ups, mainly near the ranges, producing some isolated downpours in the late afternoon or early evening. There's also a low chance of a shower either morning or late night in Southland.
Confidence votes 8.4K. A substitute for dried/dessicated shredded/flaked coconut will depend on the recipe. Most use it for flavour and texture. In some recipes, rolled oats or wheatgerm could be the subsitute, but be aware that this will give a very different flavour, and is not suitable for some recipes.
You can thin out the batter as much as you like. You can also add some shredded coconut (unsweetened for low carb/Paleo), fruit, a mashed banana, chocolate chips, or nut butter to the pancakes to mix up the flavors. My personal favorite is shredded coconut and a touch of lime zest in the batter. Yum.
