Breeze index

A sea breeze is a regular coastal wind that blows from the sea toward the land during the day.

Weather models often underestimate its strength, so we calculate the likelihood of a sea breeze separately, on a scale from 0% to 100%. The higher the percentage, the more favorable the conditions are for a noticeable sea breeze to develop.

Bar height = chance for that hour A full-height bar is 100%. Numbers below the chart are local time.

Colour = the strongest of the day The colour matches the day's maximum — so you can compare days.

What conditions matter?

01 Land–sea temperature difference The main driver. The bigger the contrast, the higher the chance.

02 Background wind A light synoptic wind lets the breeze set up; a strong opposing one kills it.

03 Cloud cover Clear skies heat the land faster and widen the temperature gap.

04 Water temperature and season Cold sea against warm land — spring and early summer are best.

05 Coastline shape Bays and headlands funnel the airflow and strengthen it.
