METEOROLOGY – WIND CALCULATOR
Sea Breeze Onset
A precise tool.
What is the Sea Breeze Onset & How does it work?
The onset of a sea breeze occurs when the temperature difference between the land and the ocean becomes significant enough to create a wind flow from the cooler water towards the warmer land. This phenomenon is particularly noticeable during hot summer days when the land heats up faster than the water.
v = frac{Delta T}{k} cdot d
v = wind speed, Delta T = temperature difference, k = thermal diffusivity constant, d = distance from the coast
The sea breeze onset time can be estimated using empirical models that consider factors such as the temperature contrast between land and water, humidity, and wind patterns. These models help meteorologists predict when and how strong a sea breeze will develop.

Frequently Asked Questions
What is a sea breeze?
A sea breeze is a wind that blows from the cooler ocean towards the warmer land, often occurring during hot summer days.
How do I calculate the onset of a sea breeze?
Use the formula v = (ΞT / k) * d, where v is wind speed, ΞT is temperature difference, k is thermal diffusivity constant, and d is distance from the coast.
Why does the land heat up faster than the ocean?
The land heats up faster than the ocean because it has a lower specific heat capacity, meaning it requires less energy to change its temperature.
What factors can affect the onset of a sea breeze?
Factors such as humidity, wind direction, and the presence of clouds can influence when a sea breeze begins.
Is there a specific time of day when sea breezes are most likely to occur?
Sea breezes are most common during hot summer days, typically starting in the afternoon as the land heats up faster than the ocean.
How can I use this calculator to plan outdoor activities?
By calculating when a sea breeze will onset, you can plan outdoor activities during cooler periods, avoiding the hottest parts of the day.
What is thermal diffusivity constant (k) in the formula?
The thermal diffusivity constant (k) is a measure of how quickly heat spreads through a material and is specific to the properties of the land or water being considered.
