MONTHLY WEATHER INFO For HAWAII

Temperatures in Hawaii are fairly constant throughout the year.
The average temperature can range a fair amount depending on the
exact location that you are in. There are some high mountain peaks
that can get very cold by Hawaii standards but few people desire to 
go there. To give you an understanding of the basic temperatures in
Hawaii, we will use the island of Kauai as our example. Kauai is the
Northern-most major island in the Hawaiian chain, so if anything, it is 
a little cooler than the rest except for those with the much higher 
mountain peaks. We will use the Lihue Airport as the location due to
the fact it is on the Eastern side of the island which will show the most
average temperature for Kauai. The average temperature for the coolest
month of January is 71 degrees Fahrenheit and t

JANUARY:
This is the middle of Winter. Weather can range from very nice days
to very bad, by our standards. What does that mean? 
Gusty trade winds, high northwest swell and surf, cold fronts with
gusty Kona winds. January has the lowest number of trade wind
days of between 6 and 12 days of gusty winds. On rare occasions
these gusts can get up to about 50 miles per hour. On the North shore
expect about 8 days of surf heights to be over 10 feet, with a 
chance of them being up to 20 feet, or higher.

February:
Winter is starting to wind down. Good weather will prevail for most
of this month. It is very possible to have thunderstorms with heavy
rain though. Strong winds can materialize rather quickly for those
planning any water activities. The Northwest swell activity should be
considerably less than the previous few months. On the North shore
expect the wave action to be only about 4 days of heights between 
10 and 20 feet. Maybe about 12 days will be between 6 and 10 feet. 
Over half of this month will have normal trade winds, with gusty trades 
between 4 to 10 days.

MARCH:
Spring is approaching, but be careful. There is still a chance for a 
couple of days of Winter to be heard from. There will be only about
5 days of surf on the North shore that is greater than 10 feet, but
there is a chance that it can get even higher than 25 feet. Cool !!
Expect about 8 to 14 days of gusty trade wind days, with about
7 additional days having somewhat normal trade winds.   

April:
Spring is here and we're looking for Summer. Most of this month is
quite nice, but there is an occasional outburst of April showers
coupled with some gusty trade winds. About 3/4 of this month will
have the normal trade winds, with 8 to 14 days being gusty. The
Northwest swell and good surf is starting to end with only about
2 days of North shore surf at between 10 and 15 feet high.

MAY:
Good weather is here with a small chance of a bad weather outburst.
That Northwest swell is almost gone now and the North shore swell
will be lucky to get over 5 feet high. There is a chance that it could get
up to 10 to 15 feet high, but it will only occur for a day or two, if at all.
Trade winds will take place over 80% of the time, with 4 to 10 days being
a little gusty. The swell and surf on the South shore will start to show
signs of life with the possibility of a few waves to ride.   

June:
Probably the second best month of the year, weather wise. There will be
a few gusty wind days (between 5 to 10 days), but mostly there will be 
the gentle trade winds that we love. There is a possibility of a tropical
storm, but the odds are quite low for it to appear. The South shore swell 
continues to increase and any decent waves on the North shore are 
going to be nonexistent unless a rare storm of some kind appears. 
Boaters need to be wary. The nice weather on land can make them
believe all is great but the channels between the islands can have some
rough and hazardous conditions.

JULY:
This is the #1 month for nice weather. Trade winds are fairly constant
over land and over the ocean they may be gusty between 6 to 13 days.
North shore surf is at its lowest with heights between 0 and 5 feet. Surf
on the South shore will peak this month and extend its run into the month
of September. Sightseeing boat tours of the North shore enjoy the calm
waters during the summer months and many, many tours take place.
Boaters still need to keep a watch on the horizon for any type of possible
thunderstorm with some heavy rains from an upper trough.

August:
Perfect weather continues and this is the warmest month. That additional
warmth can add to the possibility of a random tropical storm and even the
chance of a hurricane. Hurricane season in Hawaii runs from August
through November. The gentle trade winds continue through the month
with up to 10 days of them being kind of gusty. South shore surf is still up
and the North shore surf is still down. The summer months are the best
for hiking all over Hawaii. 

SEPTEMBER:
Similar weather as August with an occasional tropical cyclone. That is the
only potential down side to a perfectly great month. The surf on the South
shore is now declining and the Northwesterly swell is starting to pick up.
So surfers aren't too happy with this month unless some type of storm
appears to create some higher surf. Something to remember is that
Hurricane Iniki, Hawaii's worst in its recent past, occurred on
September 11, 1992 and its eye literally went over the island of Kauai.  

October:
Aw Shucks, Summer is over and the beginning of Winter starts to appear.
Trade winds start to decrease, but they are still prevalent most of the month.
The Northwest swell and surf begin to pick up even more with 6 to 15 foot
surf and there is even a little greater chance of a hurricane showing up. The
South shore surf is now winding down and almost at its end for the year.

NOVEMBER:
Hawaii's Winter weather begins now. The weather can change from good to
bad quickly. Bad conditions are: high Northwest swell, gusty trade winds,
heavy rains, strong Southwest Kona winds, thunderstorms and even 
waterspouts. South shore surf is now down and North shore surf is up, with
the possibility of surf that is over 20 feet high. Normal trade wind days are
now starting to decline, and gusty trade winds will increase to about 8 days
during this month.

December:
Winter type trade winds occur this month and they are usually the strongest
trade winds. The actual number of trade wind days is low, like only about half
of the days of the month, but the ones we get are pretty gusty. Northwest
swell is high and North shore waves are going to be greater than 6 feet high
for at least 20 days of the month and they can get to be over 20 feet too.
This is a pretty risky month for boaters due to the high gusty winds which
can add a lot of choppiness to the high ocean swells.
