Figures are modelled sea-surface temperature, not readings from a buoy or a thermometer in the shallows — expect a degree either way, and more in a shallow bay on a hot afternoon. Wetsuit suggestions are general guidance: cold tolerance varies a lot between people, and wind, session length and air temperature matter as much as the water does.
