Is tonight worth setting up for – and from when to when? Astrowetter answers exactly that question. With a score, a time window and an honest statement of how certain it is. ONE APP INSTEAD OF FOUR OR FIVE Until now, finding out whether a night was any good meant keeping several apps and websites open: one for rain radar, one for cloud layers and dew point, one for seeing, one for an overall score – and often a spreadsheet to compare the hourly values. The reason for all the switching: each of these tools shows a single weather model and hides the fact that the others say something different.
