Look at the weather (e.g. at http://www.bom.gov.au/vic/forecasts/melbourne.shtml) and make a judgement call. Safest is 0% chance of rain, 0 mm.

Don't expect this to be 100% accurate. Weather, particularly in Melbourne, is notoriously unpredictable. If the sky is overcast or grey, consider your moves carefully. I rarely go draining unless it's thoroughly sunny.

Some drains contain a connection to a cooling tower or other runoff (sometimes illegally installed) from a nearby factory or other building. These sometimes dump their water into the drain, causing a temporary 'flood'. Other water sources, such as firefighting equipment, burst water mains and people washing cars, can also do this. However, you shouldn't assume this is the always the case and when you do see a rise in water levels, leave as safely and quickly as you can.

Not sure what you mean by 'water drops'. If you mean droplets of water on the ceiling, that might be water evaporating from the base flow (i.e. the water constantly flowing through the drain) and condensing on the ceiling, which might be colder in some parts depending on how the drain changes in height. If it's a constant drip, it may be water leaking from an old mains or just the base flow from a tributary to the drain (i.e. a sidepipe).

Some drains always have water running through it. (Possibly from a side pipe.)

But it's always good to check the radar (e.g. BOM) just before you enter.

I always keep an eye on the water. Usually running water will be clear (or cleanish) as the dirt and gunk can't build up in the water. If this clarity changes you know that it is probably a new source, possibly side pipe or road run off. Then you haul ass! I'm not sure it would be relevant in winter but water temperature is another indication of rain above. In summer roads get hot, thunderstorm comes, water hits the road heats up and goes down a drain. Hot water is usually an indication of new source nd once again.. Haul ass!
Melbourne weather is very unpredictable and for dangerous for drains, lucky I live in Sydney haha! Hope this helps :D
Just as evolution intended, I was designed by DFEX..

Hahaha burst water mains are fun I encounter one in 69er I'm tempted to go throughout that tunnel but I need a big umbrella

I've posted it before, but 'Pocket Weather AU' app shows the predicted rainfall on an hour by hour basis, as well as having the radar, and tide chart. I don't drain unless the prediction is 0%, and the radar is clear.
