In the couple years I've been boating in RP, from my experiences its always been very unpredictable. We usually fish about 50 miles out, and when we were heading out there about 3 weeks ago we only seen three whales, and a week later when we went out to the same spot we seen 30-40 whales, at one point we had about 7 whales right around the boat, and one whale put on an incredible show leaping out of the water. Sometimes the whales are 10 miles out, sometimes they're 30-50 miles out. I'd guesstimate that if you went out anytime in February or March you'll see at least one whale, but overall it's anyone's guess. I know, pretty vague answer. And as a side note, last year we seen a lot of dolphins every time we went out, this year we've seen hardly any.
