Default Sea Breezes


I would like to know more about how sea breezes develop and under what conditions, what weather conditions do you need for them to start etc.

the conditions they start are sunny days
The calmer the weather the more noticeable they are. They reach just offshore maybe 2 miles usually 1 mile
Heating and cooling of the land mass is the cause.
As the land heats up during the day the air above the land raises causing cooler air over the sea to rush in and replace it,
As the land mass cools more than the sea during darkness the opposite effect is created
In general afternoon and evening more onshore wind, with mornings more offshore winds
These winds can be added or taken from the general wind increasing it or decreasing it significantly therefore small boat sailors should be aware of this.

I know quite a bit about sea breezes. They are basically a circulation that is confined to the boundary layer, ie below 1000ft. The conditions to look for are lines of cumulus clouds along the coast and clear skys seawards. This is a big clue that the circulation has been set up.

As above

You will also need clear skies in the morning to allow the land to warm up as well as light winds. If you alreay have a decent wind the sea breeze will not get a cance to kick in.

In many resorts they can tell you what time the sea breeze will kick in every day month by month. IN the UK we tend to get them most on the S coast in the summer months on windless morinings. Typically kicking in between 1100 and 1300

Hmm interesting, I live close to the water and this just about explains everything. Nothing smells better than a nice cool sea breeze.
