IPA: /koʊˈtaɪdəl/
KK: /kəʊˈtaɪdəl/
Describing a situation where high or low tides happen at the same time in different places.
The cotidal lines on the map show where the tides are synchronized.
Cotidal → It is formed from "co-" (meaning together) and "tidal" (from Latin "tidalis", meaning related to tides). The word "cotidal" refers to phenomena that occur together with the tides.
Think of 'together' ('co-') and 'related to tides' ('tidal') to remember that 'cotidal' describes things that happen at the same time as the tides.
