Fog changes the feel of the day
Coastal fog can reduce visibility and make a bright inland forecast irrelevant at the seafront. Carry a layer, use headlights when conditions require them, and leave extra road margin rather than treating fog as a guaranteed photographic effect.
The Atlantic is cold and exposed
The Benguela upwelling system brings cool water to the coast. Air temperature is not a water-safety test: look for an open designated bathing area, read the signs, and ask a lifeguard or authorised official about that day’s conditions.
Wind affects more than comfort
Wind can alter surf, sand, kayaking, flights, beach walks, and desert activities. Ask what threshold changes or cancels an outing and whether the operator refunds, reschedules, or substitutes another route.
