WATER TEMPERATURE YING KO HAI

TODAY, TUESDAY, 17 MARCH 2026

Current Temperature air / water

17 MARCH 2026, 16:38 h

Water temperature plays an important role in the behavior of fish. When the water is cold, fish are lethargic and inactive, and the same happens if the water is too hot.

At this moment the current water temperature in Ying Ko Hai is -. The average water temperature in Ying Ko Hai today is -.

The effects of Water Temperature

Fish are cold blooded, which means their metabolism is strongly influenced by the temperature of their surrounding environment. Fish want to stay comfortable. Consequently, even a small change or break will cause fish to move from one location to another.

In general, this behavior varies for each species and place, so we can not specify an ideal water temperature, however as a general rule we will try to avoid the temperatures abnormally cold in summer and too warm in winter. Remember, look for the comfort zones and you will find the fish.

NOTICE

Our prediction algorithm for water temperature is in development phase. Although in most places we get a value very close to the actual sea water temperature, it may not be accurate in certain areas. Please, use with caution.

Current wave conditions

17 MARCH 2026, 16:38 h

Wave direction - (-°)

Significant height -

Wave period -

Most frequent waves

The most frequent wave height will be about half the height of the significant wave.

Significant height

About 14% of waves will be higher than the significant wave height (about 1 in every 7 waves).

Maximum waves

It is normal to expect a wave of twice the height of the significant wave about 3 times in 24 hours.

This means at this moment you need to be prepared for a wave of - before heading out on the water.

Significant wave height

It is normal for waves to vary in height from one to the next. To give you an idea of the range of waves to expect at a given time, we consider the significant wave height as the average height of the highest third of the waves in the open sea.

The significant wave height provides an estimation of wave heights recorded by a trained observer from a fixed point at sea because we tend to pay more attention to the larger waves.

MORNING

AFTERNOON

Tidal coefficient

17 MARCH 2026

The tidal coefficient today is 90. With such a high coefficient we will have big tides and the currents will also be very evident. At noon the tidal coefficient increases to 95. The day ends with a tidal coefficient of 100.

The heigh of the tide is 0.4 m referenced to Mean Lower Low Water (MLLW).

We can compare these levels with the maximum high tide recorded in the tide tables for Ying Ko Hai which is of 2.3 m and a minimum height of -0.2 m.

The following graph shows the progression of the tidal coefficient in the month of March of 2026.These values give us a rough idea of the tidal amplitude in Ying Ko Hai, forecast in March.

Large coefficients indicate important high and low tides; major currents and movements usually take place on the sea bed. But bear in mind that this tidal amplitude may be greatly affected by the weather and you should also consult the weather forecast in Ying Ko Hai, the wind in Ying Ko Hai and the surf forecast in Ying Ko Hai before you go fishing.

best periods of the year

The solunar periods indicate the best times of day for fishing in Ying Ko Hai. The major periods correspond to the lunar transit (passage of the moon over the meridian) and the opposing lunar transit and last approximately 2 hours. The minor periods begin with the rising and setting of the moon and its duration is approximately 1 hour.

When the solunar period coincides with sunrise or sunset, we can expect more activity than initially planned. These peak periods are reflected in green. We additionally point out in the chart the periods of greatest activity during the year with a big blue fish on the period bar + info
