We’ve been reading of recent flooding in Laos. Davidfl keeps readers aware of flooding in Thailand. When it comes to Vietnam, however, there is little reliable information to assist those seeking to find ‘when is best time to ride in Vietnam’. As part of the on-going efforts of this site to put together an image of possible, even likely weather patterns in Vietnam here’s an article published by VIETNAMNET earlier this year: According to the Center for Hydrometeorology Forecast of the Central Region, every year, there is an average of 11-12 storms and tropical depressions in the East Sea, with an average of 5-6 storms and tropical depressions directly affecting Vietnam. In 2013 14 storms and five tropical depressions affected Vietnam, reaching the highest number of storms and tropical depressions on the East Sea in history with the Central Region of Vietnam being directly affected by four storms and one tropical depression from mid- September to mid- November. In 35 years (1964-1999), on the Vu Gia – Thu Bon river valley in Quang Nam province, there were only two major floods but since 1999, the frequency of large floods has increased remarkably. Historic floods have appeared in the rivers in Quang Ngai province over the past 30 years. The flood in 1999 surpassed history within 35 years, but in 2009 the Tra Bong River flood broke the record of 1999. In 2013, flood peaks on the Tra Khuc and Ve rivers set a new record. The Hydrometeorological Forecast of the Central Region said climate change has made for unusual weather with extremes of climate and weather – more storms & more floods both more powerful than before. The annual average rainfall in 2013 exceeded the annual average by between 114% to 119% with significant increases being seen between October to March & in July and August. In the past, floods usually occured in Thua Thien – Hue from September to November, but now it occurs earlier & over a longer period (from August through December). Floods occur with increasing intensity, with higher flood peaks and with stronger flow. Severe Salinity Da Nang City is primarily provided water from only one river – Cau Do. However, unlike in the past, the salinity of water is now very high in the dry season, up to more than 1,000 mg/l in some years.The Cau Do Water Supply Company said that this phenomenon has occurred from mid-2012 and it is a very unusual phenomenon. Sometimes, salinity is more than 10 times of the permitted level & impacts greatly on the lives and activities of city residents, especially thousands of hectares of rice fields. It’s clear that if riders wish to avoid getting a wet **** it would be advisable to consider the above findings in conjunction with any tour planned. The findings concerning Da Nang are of interest to those considering an extended stay.
