temperature of the water near the shore is rapidly lowered by 
a westerly or off-shore wind, and is as quickly raised by an 
easterly wind, independently of the temperature of the air.* 
But the effect is often somewhat masked, in summer, by reason 
of the much higher temperature of the westerly winds, which 
quickly warm the water close to the surface. Observations 
made early in the morning, before the effect of the direct heat 
of the sun becomes apparent, are the best for detecting the in- 
fluence of tidal and wind currents.
