My guidance here is based on your desire to have the gold in your city-radius. It looks like there is a rather large un-used hinterland on this continent which might be more profitable in the long-run. You might be able to fit another city or two on this land, but it is my philosophy that you shouldn't build two cities to do a job that can be accomplished by one. A save file or a screen-shot farther west would be more useful for properly evaluating this location.
One square west of your current position looks appealing. You get cows and some more land-tiles. This comes at the cost of coastal access and the ability to have a lighthouse for that one little piece of shore you'll still have, but in this environment, I think that food will make up for it.
I will refer to your current location as "Current", and the alternate build-site "West1".
Let's look at what all they have:
Current: 8 empty, 5 coast, 3 hills (2 desert, 1 plains) with a gold, 2 floodplains, 1 grassland with copper, 1 plains. Is coastal.
West1: 9 empty, 1 coast, 3 hills (2 desert, 1 plains) with 1 gold, 2 floodplains, 2 grassland with a copper and cattle, 3 plains (2 forested).
Basicly, the difference between the two sites is 2 plains-forests and a grassland-cow instead of 4 coasts and coastal access.
If you cottaged the plains, then the in combination with the cow, they would produce a break-even amount of food, the same amount of commerce (eventually), and 4 more hammers. The commerce yields are basicly the same, but West1 does it with 1 less citizen.
Finally, what is the impact of being coastal here? Coastal cities, I belive, get an extra trade-route and access to better routes than their land-locked brethren. In addition to this, you can build a harbor for a 50% bonus to the city. In total, being coastal will add about 6-7 commerce (though this depends on civics, technology, and wonders).
Whereas the Current location will gain you 6-7 commerce, West1 will net you 4 extra hammers and a greater available food surplus. West1 will become productive sooner than will Current, since it can grow in population and build buildings faster. Current will give you the quickest boost in commerce.
Given that you are founding a city in 1325, I think the quicker-growing option will be the better bet. Build the city 1 square west of your current location.
