high pressure
NEXT DAY UPDATE
WEDNESDAY...surf is on the way down for northern shores as the recent northwest swell fades out. surf up that way will remain small and weak for the remainder of the work week and into the weekend. the north pacific is a mess of weak areas of low pressure and under the rule of a predominant high pressure that will fuel strong trades across the northeast pacific. as a result of the trades wind swell will start to incease along eastern shores and stay near advisary levels for most of the week. winds are modeled to also fill in over the islands and the forecast looked solid for today, but as i was outside all day i really never saw any heat relieving winds...maybe tomorrow?
5-DAY OUTLOOK
north pacific is on strike with a chaotic and unorganized week ahead. with the dominant large area of high pressure taking hold in the northeastern pacific there is little in the way of low pressure areas north of hawaii. generally speaking the north pacific high, as it is sometimes refered to, tends to be strongest in the summer and as a rule dictates weather in hawaii. when the high pressure is at its peak it is accompanied by strong winds circulating clockwise around the center. with hawaii at the southern base, depending on it location, the trades take their reconizable easterly flow. if the north pacific high is more north than northeast of hawaii the winds will tend to be more northeasterly as opposed to southeasterly when the low moves toward the west coast of north america. also, when the north pacific high takes its grip large areas of low pressure are frequently absent in the north pacific and the end result is poor surf production for hawaii.
models are showing the north pacific dominate by the high for most of the week. the jet stream has moved further north than normal for this time of the year and with this occurence there is little chance of cold northern air to interact with tropical miosture and that is the catalyst is for surf production. looking at the charts this patten will remain with us for the remainder of the week right through the weekend. any low pressures forming west of the date line will likely be deflected by high pressure to the east and never reach their full potential.
east facing shores of hawaii will see large windswell as both strong winds locally and upstream are abound. surf will reach advisary levels tomorrow and possible thursday and begin to drop late thusday although tradewind swell will be around through the weekend.
southerns shores will see some small bumps during the rest of the week with maximum sets near head high.
