What does spiking mean?
Spiking describes a sharp, sudden, and usually conspicuous increase in something. It is especially common when discussing prices, demand, interest rates, temperature, pain, or measurements on a graph: demand may spike, prices may spike, or a patient's fever may spike. The expression suggests more than a gradual rise; it conveys a rapid movement upward that may be temporary or alarming. Because “spiking” is the present participle of “spike,” it commonly appears in ongoing or descriptive statements such as “costs are spiking” or “the curve spikes sharply.” In more formal or quantitative writing, “rose sharply” or “increased dramatically” may be preferred. The word can also be used as a noun for the increase itself, though this use is less common. Overall, spiking is a useful term whenever an abrupt rise is more important than the precise amount of change.
To rise or increase sharply and suddenly.
"House prices spiked during the summer."
Common in descriptions of economic data, demand, temperature, pain, and graph lines.
A sharp, sudden increase or rise.
"There was a sudden spiking in demand for emergency supplies."
Less common than the verb form and often used with “a” or “the,” as in “a spiking in prices.”
A graph spikes when a line suddenly shoots upward—exactly the metaphor behind using “spiking” for prices, demand, or fever.
