Weather and Terrain

(010800H to 310800H July 1965)

The weather was generally clear during this period, no rains during the first 25 days, with occasional showers during last six (6) days.  The heat had some effect on movement of troops during afternoon hours in the heavily vegetated areas in the western sector of 1/4 TAOR.  Reflected heat from sand and little wind variation accounted for abnormally high heat in western area.  Occasional thunderstorms during last six (6) days had little effect on wheeled vehicles.  On roads, traffic ability is considered fair with low areas becoming untrafficable to M-274 vehicles and moderately trafficable to M-422 vehicles.  Off road trafficablility is fair in some areas but poor to untrafficable in most areas due to rice paddies/thick undergrowth/deep sand.  Vegetation had no effect on troop movements or observation in the peninsula area; however thick undergrowth impaired visibility and movements in some part of the western operating area.  Water movement by tracked vehicle was hampered by low tides and uncertain bottom positions surrounding island at Ky Xuan vicinity (BT 4910.
