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.
At this moment the current water temperature in São Martinho do Porto is -. The average water temperature in São Martinho do Porto today is -.
We consider the waves in the open sea.
The waves you will find on the shore can be slightly affected by the orientation of the coastline and the seabed of the beaches, although in most cases they are usually equivalent.
Today Thursday, 26th of April of 2018, the sun will rise in São Martinho do Porto at 6:43 h and sunset will be at 20:26 h. In the high tide and low tide chart, we can see that the first high tide was at 1:02 h and the next high tide will be at 13:39 h. The first low tide will be at 7:24 h and the next low tide at 19:43 h.
Today we will have 13 hours and 43 minutes of sun. The solar transit will be at 13:34 h.
The tidal coefficient today is 80, a high value and therefore the range of tides and currents will also be high. At noon the tidal coefficient increases to 84. The day ends with a tidal coefficient of 88.
We can compare these levels with the maximum high tide recorded in the tide tables for São Martinho do Porto which is of 4.1 m and a minimum height of 0.1 m.
The following graph shows the progression of the tidal coefficient in the month of April of 2018.These values give us a rough idea of the tidal amplitude in São Martinho do Porto, forecast in April.
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 São Martinho do Porto and the wind and wave forecast in São Martinho do Porto before you go fishing.
Today we begin the day with the moon already visible in the sky, so first we will see the moonset, which will take place at 5:05 h at 280° west. Eventually, the moon will rise again in the east (83°) at 16:47 h.
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
