The weather in Maine in May is just perfect for local business owners who are readying their shops, restaurants, hotels, inns and B&B's in anticipation of summer...

...for the early season tourists who want to enjoy Maine, without the crowds...

...and for the once dormant trees, flowers and bushes to return to life with their spring like colors.

By mid-to-late Spring, popular Maine tourist attractions, and...

...both indoor AND outdoor activities and events in Maine are enjoyable.

With more sunshine forecast in May, than in March or April, the days are usually brighter, and the number of daylight hours is longer....

...as the calendar heads towards the June summer solstice, which in the Northern Hemisphere is the longest day and shortest night.

And, and as is the case in all of New England at this time of year, the weather in Maine in May is generally warm enough to be snow free - FINALLY!

May Maine Weather Forecast

Among the interesting facts about Maine, you find that it's a BIG state, covering 33,215 square miles that stretches 320 miles in length and 210 miles in width. Because of the state's tremendous size, the weather in Maine in May can vary from region to region. But for the most part...

...unless you are traveling in Maine's mountains, or near the Canadian border, you can hope for average daytime temperatures to be in the low 60's, with nighttime readings in the low to mid 40's.

At this time of year, however, it is not unusual for temperatures along the coast of Maine to be cooler than temperatures inland. This is due to coastal air being cooled by the chilly waters of the Atlantic Ocean.

Regardless, you are likely to experience very pleasant, spring-like Maine weather conditions, in May, wherever you travel in the state. But do expect some rain...

...although, measurable rain in May is typically less than it is in the early Spring, Fall or Winter months. And on rare occasions...

...usually only in northern Maine or higher elevations, a record low temperature in Maine in May can produce precipitation in the form of freezing rain, sleet, or light snow showers.

Checking the extended weather forecast for Maine, prior to your trip, will let you know what to expect AND what to pack! You don't want too many surprises...

...like the 96 degree May record high temperature in Bar Harbor, Maine...

...or, as reported by the National Weather Service in Gray, Maine, a record May low temperature in Portland, Maine of 23 degrees.

What to Wear in Maine in May

When packing for a trip to Maine in May you can leave behind your heaviest winter clothing - thankfully! However, make sure that you bring enough layers to keep warm in the event that the weather turns cold.

With several light-weight layers, you can bundle-up for warmth, and also dress down, if there is an unexpected heat-wave during your Maine vacation.

Although the weather in Maine in May is not often warm enough for summer shorts, it occasionally becomes summer-like and you may be happy to have a pair with you.

Unless your trip includes a special "dress-up" event, you will find that activities and events in Maine are quite informal. You may not need more than is on the list below.

Based on the average May temperatures in Maine, my packing suggestions are..

• Light-weight jacket (water repellent)
• Umbrella
• Rain hat and/or hat for sun protection
• Comfortable walking shoes, or boots if hiking
• Sweater or fleece top for evenings and chilly days
• Long sleeve top for layering
• Short sleeve top for layering
• Socks
• Long pants
• Capri pants and short pants (just in case!), and...

...and last, but not least, it's time to break out the sunscreen.

Depending on what Maine vacation spots you plan to visit, your trip may include a boat cruise - plan accordingly, as the weather in Maine in May along the coast can be foggy and damp. It is also much cooler on the water than it is on land.
