Scope Nights: Astronomy Weather

By Martin Dodd

Open iTunes to buy and download apps.


Find clear dark skies & go stargazing with Scope Nights award winning astronomy weather forecasts & NASA dark sky map for amateur astronomers ● Universal app, buy once & use on both iPhone & iPad, no adverts ● Uses in-app upgrades to access full features (details below).

Sky & Telescope Magazine, Mar 2015 - “Several astronomy-oriented weather apps are available, but Scope Nights has become my favorite… it does a fine job of summarizing the data in a clear and understandable fashion.”

Austin Astronomical Society, Jan 2014 - “The more-advanced astronomers will find its extended 10-night forecast feature valuable compared to other apps that limit the forecast to 48 hours. I would recommend Scope Nights to any stargazer planning his/her next night out.”

Sky & Telescope Magazine, Dec 2012 - “There’s no shortage of weather-related apps for the iPhone, but there’s only one specifically made for amateur astronomers… Our resident weather maven, who uses more than half a dozen apps and websites to prepare predictions, gives Scope Nights two thumbs up for it’s consistent accuracy”.

Customer Reviews


The weather data and predictions displayed have been about 80% accurate for me, and it seems to be quite current. I've been using it for over a year and have had no issues (I'm not sure what the bad reviews are talking about?)

A suggestion would be to add the ability to make notes on each day for planning purposes.

Went from bad to decent to bad again

It has the potential to be a great app. At first it didn't have my city or anything even close.
Then it did and it was right about 70% of the time as far as forecasts the day of. Right about 40% of the time 2 or more days out.
Now the settings doesn't work, and there are these neat upgraded features that are pretty expensive add ons.
Fairy disappointed. I think I'll just go with a weather app.

Stopped working on iPad 2

Further update - now doesn't seem to be accurate for my region. Plus, once again the developer has increased the costs for upgrades, including the functionality that was present in the original version. Why should I pay again for my original app functionality? Horrible - stay away and save yourself money and frustrations.
