"The North Atlantic just completely destroyed its June average temperature record, breaking the previous record by more than 0.4 °C (0.7 °F).
A stunningly sharp excess for such a large body of water."

But this spike is spikier than the last el Nino spike, so even if spikes do occur, this is the spikiest spike so far.
Without actually seeing the numbers and just looking at the graph, it seems like there are several historical instances of a similar year-over-year spike of similar magnitude - around 1860, 1990 and a few more (I am doing that from memory, dates not exact).
