Answer:
-being closer to the ocean
-ocean currents bringing cooler air
Explanation:
Generally, coastal areas closer to the sea receive more moisture, while areas farther away receive less moisture. Therefore, the higher the continentality, the lower the humidity and the higher the thermal amplitude, and the higher the maritimity, the higher the humidity and the lower the thermal amplitude.
This means that the areas located within the continents (continentality) vary their temperatures more. Already the regions closer to the sea (maritimity) tend to have more constant temperatures during the day and even throughout the year, because the air is wetter in these locations. In addition, regions near the ocean have lower temperatures because the sea currents bring cooler air.
