Camping Hiking Geocaching
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Find your perfect weather anywhere in the world for your camping trip or weekend getaway for hiking, biking, geocaching or other outdoor activities - with traffic light colors on the map!
Green = perfect weather
Red = better not go!
SunOnly shows you not only where the weather is right, but also when: You set your weather criteria, choose a time period and map area, and the map clearly rates places according to your personal conditions. In addition to temperature, rain, snow and cloud cover, you can now also include feels-like temperature.
And if you already have favorite destinations, planning gets even faster: Automatically rated favorites and POIs show you at a glance which of your saved places will have the best weather in the selected time period.

2.1 12/20/2025
In the detailed weather search, you can now choose whether only the regions on the map should be marked in green where all weather criteria are met throughout the entire selected period, or whether you want to see a temporal evaluation, where in dark green regions all weather criteria are always (100%) met, while in contrast in yellow, orange, or red regions all weather criteria are met less frequently or never.
New for surfers, kitesurfers, sailors, etc.: In the detailed weather search you can now also search by wind direction. This helps, in combination with the search for wind strength and other criteria, to find the perfect spots for water sports.
From this version, weather data is retrieved with an accuracy of 1 hour for the first 4 days (instead of 3 hours as before). From the 5th day, weather data is used that distinguishes between morning, noon, evening, and night. Many thanks to the subscribers of the "Pro Edition", who make this possible with their contribution!
With a new button, you can now display weather details or details of a POI that you previously closed again.
The weather criteria of the detailed weather search are now retained when you close and restart SunOnly.
Normally, compared to version 2.0.2 and earlier, only 50% of the weather data is retrieved from the server. This reduces data usage (especially important with expensive mobile data packages) and loading times decrease.
Some minor bug fixes.
2.0.3 09/25/2025
Bug fixes. Ready for iOS 26. Acceleration of network access and reduction of server requests. Migration of the weather data service to Pro server.
2.0.2 09/15/2025
SunOnly v2 includes a lot of new features for campers and outdoor enthusiasts:
* In addition to the previous map display with simple criteria selection, there is now a detailed weather search. Here, you can define rules yourself that your dream weather must meet. The map highlights exactly the regions in green where all conditions are fulfilled. All other regions are shown in grey.
* SunOnly now includes global points of interest especially for campers, which are automatically shown on the map when you zoom in. These points are particularly interesting for “rooftop tent nomads”, vanlifers, long-distance hikers, etc., as they can display not only campgrounds, parking spots, and supply points, but also public toilets, showers, swimming pools, laundromats, and laundry services.
* Weather information on the map is now in higher resolution.
* The map view can now be switched between standard, satellite, and hybrid. This allows you to see the actual conditions at a potential destination.
* Tapping a location on the map now gives you the option to view its surroundings in Apple Maps or Google Maps or even start navigation directly. This allows you to quickly check, for example, how long it would take to get there.
* Various small improvements.
