JANUARY
Temp.	-2°C
Temp. Range High to Low	0°C to -7°C
Daily Sunshine	3 Hrs
Rainfall	80 mm
Rainy Days	24 Days
Sea Temp.	2°C
Weather Roundup January is the month winter really kicks into high gear. With an average temperature of around -2°C and ranges of 0°C to -7°C, January will see very large snow falls with intermittent blizzards. It is a great month for all types of winter sports and the skiing areas including the famous NISEKO area will be in full swing. Travel on roads by car or bus can be difficult, dangerous and sometimes delayed. Hokkaido is well used to these types of conditions though so the roads are well maintained and snow-cleared quickly. Those without winter driving experience are advised to take extra caution. The month will see a lack of daylight hours here so expect very short days. Make the most of the sunlight and get up early! Although there can be pleasant bright days, the weather can turn very suddenly and very strongly. Nights will be well below freezing so caution should be taken when outdoors. Sea temperatures will be a measly 2°C average. Towards the end of the month is the time of year to look for sea ice on the north-east sides of Hokkaido. Central Hokkaido and the Taisetsu Mountain region will see the largest snowfalls and Eastern Hokkaido will see the coldest temperatures. (Temperatures here can drop to -20°C and below.) Buildings in Hokkaido are made for the cold weather and inside will be warm, however outside you will need, good thermal gear, hats and gloves.

FEBRUARY
Temp.	-4°C
Temp. Range High to Low	0°C to -7°C
Daily Sunshine	4 Hrs
Rainfall	63 mm
Rainy Days	22 Days
Sea Temp.	1°C
Weather Roundup The winter marches on in February. Just like January, expect heavy snowfalls and blizzards. February traditionally sees the largest amount of snow in the Hokkaido region so those wanting to experience the fluffy white powder in the WINTER RESORTS areas need to book ahead to get in at this time. Resort areas can be fully booked out 6 months to a year in advance! So plan ahead! February will however see some crystal clear days. These days, especially after a heavy snowfall the previous day, will make for some magical scenery. Skiing, snow boarding, trekking, sea ice watching and all things WINTER ACTIVITIES are the go in February. For those who don't mind bathing naked with others, a good hot spring bath is also a big recommendation at this time of year. (For bathing etiquette please - CLICK HERE) While winter resort areas will be packed, the rest of Hokkaido will be less so and many tourist places will be easy to access if you are willing to put up with the cold. There are many winter EVENTS in February, including the world famous SAPPORO SNOW & ICE FESTIVAL. With sea-temps of a rather brisk 1°C, sea ice and ice bergs off the coast will also be visible in the north-eastern areas.

MARCH
Temp.	1°C
Temp. Range High to Low	5°C to -3°C
Daily Sunshine	5 Hrs
Rainfall	64 mm
Rainy Days	22 Days
Sea Temp.	1°C
Weather Roundup March is the month of slight weather madness. Winter can still be in full force with snow and below freezing night time temperatures. However days can be sunny and even reach double digits, especially toward the end of the month. Roads will be icy in the evenings so take caution when driving. Ski fields will still be open and some great powder days can still be had, however as the month goes on the snowfall can become wetter and heavier. March is a difficult month to pack for as a traveler. Layering your clothes is the name of the game in March. Wear clothing that can be added or removed as the conditions change during month and even the day. Low land areas will begin to see more rainfall in March and this can make Hokkaido a fairly wet, and slightly unpleasant place to be. The end of March and early April will be the least scenic time to visit the Hokkaido region, this does mean however, that tourist destinations can be easier to access. Sea temperatures will however around the 1°C mark.

APRIL
Temp.	7°C
Temp. Range High to Low	11°C to 3°C
Daily Sunshine	7 Hrs
Rainfall	79 mm
Rainy Days	18 Days
Sea Temp.	3°C
Weather Roundup April will see the first small indications of spring coming to Hokkaido. Snow in the city and low land areas will begin to melt early in the month and will mostly be gone by the end. Mountain areas will still be covered and the snow pack in these regions can be very unstable and prone to avalanches. It is strongly advised to NOT climb, ski or do other activities in the high mountain, wild areas in this time period. Most WINTER RESORTS will close in or be closed by April. Average temperatures will climb well above freezing for the whole month of April, with a fairly wide range of 11°C to 3°C. This means, the day time can be sunny and pleasant with very chilly night times, especially when the wind picks up. Pack a range of clothing with an emphasis on layers. Some early spring flowers and skunk cabbage will begin to show their colors in April. The trees and other foliage will still be bare during the early weeks but will start to come on toward the end. April is usually still too early for the famed Japanese cherry blossoms, however as world wide weather patterns are changing this is not always the case and flowers can come out in late April, especially in SOUTHERN HOKKAIDO Sea temperatures will begin to rise from April but are still a frosty 3°C average.

MAY
Temp.	12°C
Temp. Range High to Low	16°C to 7°C
Daily Sunshine	7 Hrs
Rainfall	74 mm
Rainy Days	17 Days
Sea Temp.	7°C
Weather Roundup May will see the true begging of spring in the Hokkaido region. Snow in the low land areas will be basically entirely gone and many of the early spring flowers will be out and showing their colors. Snow will still be visible in the higher mountain areas and the trees will not have full foliage until the late end of the month at least. May is also the Jekyll and Hyde month of weather, with absolutely beautiful warm sunny days followed by chilly, rainy and windy ones. The cherry blossom front will be moving through Hokkaido during May and many EVENTS in relation to this can be found around Hokkaido, as well as other flower events. Obviously the cherry blossoms will start south and move north, so if you are trying to catch them plan your trip accordingly. If you are looking to see the full blooming flower fields of Furano and Biei, May will still be too early. Average temperatures will increase significantly in May into the double digits. Heavy winter coats are usually no longer necessary but pack a light coat and a good sweater. Hokkaido's rainy season will begin in this month and the number of rainy days will increase. (Umbrellas can be bought cheaply at almost every convenience store in Japan if you are without one.) The rain will bring with it chillier temperatures that will have you wanting your warm sweater and maybe even your coat. Sea temperatures will increase markedly in May which will bring to an end any chance of seeing floating icebergs in the NORTHERN HOKKAIDO areas.

Temp.	16°C
Temp. Range High to Low	20°C to 12°C
Daily Sunshine	7 Hrs
Rainfall	84 mm

Weather Roundup June will see spring in full bloom, almost all of the early flowers will be out, the trees will have their full plumage. Temperatures will continue to rise through the month and beautiful sunny days can be expected. Days that are good in June are spectacular. A healthy average of 16°C with a 20°C to 12°C range makes for comfortable conditions. Day time highs can move into the mid 20's on nice sunny days. Conversely, chilly winds from the north can still bring the temperatures down quickly and jackets will be necessary. The beginning of the month will see frequent showers and rain with the weather here being much more MAY like. The later half of the month improves dramatically. The rainy season is however much shorter and less dramatic than further south. Remember that basically every convenience store in Japan sells cheap umbrellas if you get caught out. Daylight hours will also be much longer, giving visitors plenty of time to visit their favorite sites and take part in some of the EVENTS of the month. Sea temperatures will rise as well and all the lake and river scenic spots should all have reopened by June for the out door types.

Temp. Range High to Low	23°C to 16°C
Daily Sunshine	6 Hrs
Rainfall	117 mm
Rainy Days	17 Days

Weather Roundup Summer is finally here! After the long winter and the off and on heat of the spring July will see consistently warm and even hot days, especially at the end of the month. The daytime will be sunny and warm and ,during the day at least, you can finally put away that jacket or sweater. July averages 20°C with highs of 23°C plus. The evenings will still see the temperatures drop off to lows of around 16°C though so it may be wise to keep something a little warm to put on if you will be out at night. Rainfall will increase significantly in July which combined with hot days can create a lot of humidity but it is still much less and more comfortable than the southern regions of Japan such as Tokyo and Osaka. With the warm temperatures the local Hokkaido population goes crazy for the outdoors with camping and hiking areas often very crowded. There are also plenty of EVENTS in this time period to help you celebrate the Hokkaido summer. Sea temperatures will also be relatively warm, allowing for some swimming on the hotter days.

AUGUST

Temperature differences between the night and day can be quite large at times so be careful if you are susceptible to the cold. August will have plenty of things to see and do including a whole range of EVENTS. Flowers in the CENTRAL HOKKAIDO area will also be out in force, although some types may already be harvested depending on conditions. Tourist crowds will also have their summer peak in August, so be ready for some busy areas. The sea is warm (relatively) and swimming is definitely possible, although some coastal areas such as KUSHIRO can become quite foggy. Indeed Kushiro is known as 'the city of fog'. Be aware the sun can be quite strong, even if it doesn't feel so. Take precautions for your skin.

The tail end of the typhoon season down south will affect visitors weather experiences here. beautiful days and rainy colder days will be mixed together. The night times will be noticeably cooler especially in the later half of the month. Early mornings will also be crisp and cool and fog will be an issue for those wishing to catch views of some of Hokkaido's famous lake areas. Although the days a getting shorter there is still a decent length of daytime to enjoy some of the harvest and food type of EVENTS that are common around this time.

With the average temperature at a modest 12°C and a range of 16°C to 7°C, October weather tends to be quite consistent and the real winter chill air will usually not arrive until November. A decent sweater or jacket, and you will be set to get out and get all those gorgeous nature lovers photos. The days are shorter but less humid than the Summer months with mostly crisp, clear air. October is the end of the traditional harvest season and is also a good month for foodies as there are quite a few associated food and wine EVENTS to be enjoyed.

Weather Roundup December brings with it the true beginning of winter. The highlands will well and truly be getting covered in snow. The trees are all bare and ready for the coming winter. The ski season truly kicks off in December with Hokkaido's WINTER RESORTS usually fully up and running, although base coverage can still be somewhat thin in areas. The air will be very crisp and cold at night so warm clothing is a must. The month will start out relatively mild with temperatures usually dropping sharply around mid-month. This is also usually the time that snow starts in the more lowland areas. Once covered Hokkaido's winter scenery can be truly breath taking. Rainfall is very low in December which is great but sunlight hours are also very short. Therefore if you want to get out and explore, do it quickly! Sea temperatures have also dropped considerably by this time making ocean activities out of question or very cold endeavors. However it will still be too warm for the sea ice to form.
