Accurate sunrise and sunset times

  Why use Suncurves?

Are you selling a house in a sunny spot with marginal terrain or mountain shading effects? We can help you get a higher price for that house by documenting its sun index. Or if you're looking to buy a house, wouldn't you like to know its exact sunlight conditions throughout the year? We have developed a unique method to compute the accurate sunrise and sunset times for every day of the year. The sunrises and sunsets we compute are not the ones you would find elsewhere on the web, because other sites do not take the terrain into account. Our sunrise is when the sun goes up from behind mountains or hills in the east, not when it goes up over the level horizon. In mountainous regions that can make a huge difference. We also compute the monthly mean cloud cover based on satellite data.

We now have 2544 registered and we've computed the sun conditions for 27306 locations. Join us!

Our main product is the location view. It costs 25 Suncurves credits for each view that you create, but you get the first one free (because you get 25 credits as a welcome present). Later, you can get more credits with discounts of up to 50%. The location view shows you all there is to know about the sunrises and sunsets for a given location. Click below to see a demo.
