You could try WeatherShift developed by Arup Associates in conjunction with someone else whose name I've forgotten.
I believe you must upload your base weather file in epw, and then it will create a future year file for free for you.
You can also purchase "pre-made" future year weather files in epw.
A few technical caveats or explanations:
1. All these weather shifting programs work by "morphing" an existing weather file by changing the monthly averages and daily range predicted by the Global Circulation Models (GCM), i.e., climate change programs, i.e., they assume that the underlying climate patterns do not change but only shift. However, most experts say that Climate Change will likely lead to greater instability in the atmosphere so that extremes will be more intense and longer-lasting. Effects such as these will not be reflected in the "morphing" approach.
2. Since the GCMs operate on a half-degree grid, the changes used
in the "morphing" are for a rather large area (50 km x 30 km)
that's applied to all weather stations within that grid.
3. Although different GCMs predict similar average trends for the whole planet, they can give very different results for different regions of the globe. That's why WeatherShift uses the results from a collection of CGMs.
4. GCMs all consider a variety of future scenarios, like those
used by the IPCC - A1FI, B2, C, D - depending on how society
responds to Climate Change, A1FI (Fossil Fuel Intensive) producing
the highest impact, and C & D producing the smallest impact
due to more use of renewables, etc.
When you get down to it, "morphing" a weather file is not
particularly difficult to do, and something I've done for several
government-funded projects for the past 12 years. How many
locations and what time scale are you thinking? If it's limited
to a few large cities and you're satisfied with work done a decade
ago, I might be able to dig those out for you.

Hi
I am looking for epw weather files for future climates. Univ of Exeter has a tool that can transform an actual year's weather file into epw, but it only works for the U.K. Is there another tool that you know of that can do the same for an arbitrary location?Thanks.İpek--
