WeatherThe weather in Singapore is hot and humid all year round. Tropical sums up the ‘weather’ in Singapore. There is a slight drop in temperature Dec- March when Singapore’s variation on the monsoon season takes place. Singaporean monsoons are very different o those in the Caribbean though, the wind does not increase, the skies simply open and when the downpour has finished the sun comes back out again! Not that bad really and certainly not bad enough justify the title ‘off-peak’ season, especially considering the rainfall is pretty high throughout the whole year (thunderstorms occur on 40% of all days!) Average daily humidity is around 85% and can reach as high as 90% early morning and evening. Links to weather sites:
Latitude: 1 degrees, 22 minutes north Longitude: 103 degrees, 55 minutes east
GeneralThe characteristic features throughout the year are high temperature and humidity, with copious rainfall and thundery conditions.WindWinds are generally light or moderate in both seasons ( NE Monsoon and SW Monsoon ); the usual weather pattern is for partly cloudy mornings inland with showers and thunderstorms developing by mid afternoon and dispersing at night. Showers and thunderstorms may drift over coastal waters and out to sea in an evening if wind conditions are appropriate, particularly during the NE Monsoon season.North-East Monsoon Season - December to MarchNortheast winds prevail; sometimes-reaching 20 km/h. Cloudy conditions in December and January with frequent afternoon showers. Spells of widespread moderate to heavy rain occur lasting 1 to 3 days at a stretch. Relatively drier in February till early March. Also generally windy with wind speed sometimes-reaching 30 to 40 km/h ( about 16 to 22 knots ) in the month of January and February.In February, the wind at the race site will be northeasterly blowing almost parallel to the coastline. Light breeze will start to build up in the morning.As it get hotter in the afternoon, the wind will reach its maximum and remain constant till about 5.00 pm before dying down to dead calm before sunset. Then, the night sea breeze sets in from the southwesterly direction. The race site is in the West Johore Straits. There are no tall buildings on the Singapore coastline and the Malaysian side, therefore the wind directions are not affected. During light wind of 8 to 12 knots, the sea is relatively calm with light waves of less than ˝ m. In stronger wind above 16 knots, short swell of up to 1m can be expected. Tidal CharacteristicsThe tide is generally semi-durnial in the West Johore Straits. Flooding tide will follow the coastline in a northeasterly direction ( 030 degrees) and ebbing tide flows in the opposite direction. The tidal stream average about 11/2 to 2 knots. Because of reclamation, the tidal stream is stronger on the Singapore side of the two coastlines.Traffic DensityThe West Johore Straits is relatively quite compared to other parts of Singapore. There are no shipping traffic or fishing activities at all because of the causeway that is adjacent the marina. Boat movements are limited to pleasure crafts from the marina and the Police Coast Guard that patrol the waters.
