That tongue of cold surface water is from the cold current that comes up the Chilean coast. The Galapagos is in there -- it's the little clump of specks west of South America on the map -- which gives it a fairly pleasant climate despite being smack on the equator (I was there in August ten years ago, and we often needed light jackets). It does get quite a bit of sun, but it also gets fairly frequent cloud and drizzle. Note also that there is some seasonal variation. The Galapagos has a rainy season, roughly Jan.-April, in which the water is warm and the weather is the usual hot/sticky/wet equatorial conditions.
