dublin gets sunlight for a longer duration.

Explanation:

Ocean - currents can have a significant impact on a region's climate. The Gulf Stream, a warm - water ocean current, warms the coastal areas of Western Europe including Dublin. This moderates the climate and keeps it from being as cold as one might expect given its high latitude. In contrast, no such strong warm - current has the same effect on San Francisco.

Answer:

Dublin is warmed by ocean currents.
