Samoa enjoys a consistently warm tropical climate year-round, with temperatures hovering in the mid-80s°F throughout all twelve months. The data shows remarkably stable conditions—highs ranging from 85-87°F (29-31°C) and lows from 72-75°F (22-24°C)—with that characteristic 70% humidity that's typical of South Pacific islands. While the rainfall data here shows zeros across the board (which likely indicates incomplete records rather than an actual desert climate), Samoa typically experiences a wet season from November to April and a drier period from May to October, with the wettest months usually being December through March. What's interesting about Samoa's climate is that even during the wet season, you're not looking at all-day rain—it tends to come in short, intense bursts, often in the afternoon or evening. The cooler, drier months from June to September are generally considered the most comfortable for visitors, though "cooler" is relative when you're still in the mid-80s. The trade winds help moderate that humidity somewhat, especially along the coasts, making the heat more bearable than you might expect. Worth noting that Samoa sits in the South Pacific cyclone belt, so November through April carries some storm risk, though direct hits are relatively rare.

Best Time to Visit

Beach & Relaxation
June through September offers the most reliable beach weather, with slightly lower humidity and calmer seas. The water temperature stays warm year-round, but you'll appreciate the drier conditions and gentler trade winds during these months.
Cultural Exploration
May through October works well for village visits and cultural experiences, as the drier weather makes getting around easier and outdoor ceremonies are less likely to be disrupted. September often sees cultural festivals that are worth planning around.
Adventure & Hiking
June through August are ideal for hiking and waterfall chasing—the trails are less muddy, though waterfalls might be slightly less dramatic than in the wet season. That said, the more comfortable temperatures make the physical exertion more enjoyable.
Budget Travel
November through March (excluding the Christmas/New Year period) tends to be shoulder season with better accommodation deals, though you're trading savings for wetter weather and occasional storm risk. April and May can also offer decent value as the wet season winds down.

What to Pack

Year-Round Essentials

High SPF reef-safe sunscreen
The tropical sun is intense year-round, and reef-safe formulas are increasingly required to protect Samoa's marine ecosystems.
Lightweight rain jacket or packable poncho
Even in the dry season, you'll likely encounter the occasional tropical shower, and they can be surprisingly heavy.
Insect repellent with DEET
Mosquitoes are present year-round, particularly around dawn and dusk, and dengue fever is a concern in the region.
Quick-dry clothing and swimwear
The humidity means things take forever to dry, so quick-dry fabrics will save you a lot of frustration.
Modest clothing for village visits
Samoan culture values modesty—bring lightweight pants or long skirts and shirts that cover your shoulders for cultural sites and villages.
Waterproof phone case or dry bag
Between beach activities, water sports, and sudden rain showers, you'll want to protect your electronics.
Reusable water bottle
Staying hydrated in the heat and humidity is crucial, and reducing plastic waste helps protect the islands.

Wet Season (Nov-Apr)

Clothing
Lightweight, breathable cotton or linen shirts, Quick-dry shorts and swimwear, Light rain jacket or waterproof windbreaker
Footwear
Water-resistant sandals or water shoes for muddy paths and beach activities
Accessories
Compact travel umbrella, Waterproof day pack, Hat with a brim for sun and rain
Layering Tip
Layering isn't really necessary—one light layer over swimwear is typically all you need, even during evening showers.

Dry Season (May-Oct)

Clothing
Light t-shirts and tank tops, Shorts and casual sundresses, Long sleeves for sun protection during activities
Footwear
Comfortable sandals for general wear, closed-toe shoes for hiking and reef walking
Accessories
Wide-brimmed sun hat, Polarized sunglasses, Light scarf for temple visits
Layering Tip
Still minimal layering needed—maybe a light long-sleeve shirt for sun protection or air-conditioned restaurants, but that's about it.

Peak Comfort (Jun-Sep)

Clothing
Breathable athletic wear for hiking, Light linen or cotton clothing, Rash guard for extended water activities
Footwear
Sturdy sandals with good grip, water shoes for coral, hiking shoes for rainforest trails
Accessories
Snorkel gear if you have your own, Lightweight daypack for excursions, Sarong for beach and cultural sites
Layering Tip
The slightly lower humidity makes this the most comfortable period, but you're still in the tropics—one light layer is plenty.

Shoulder Season (Apr-May, Oct-Nov)

Clothing
Mix of quick-dry and regular casual wear, Extra swimsuit to rotate while one dries, Light long pants for evening
Footwear
Versatile sandals that can handle both wet and dry conditions
Accessories
Small microfiber towel, Zip-lock bags for keeping things dry, Portable phone charger
Layering Tip
Weather can be variable, so having one light jacket or long-sleeve layer is sensible, but you won't need much more.
Plug Type
Type I (same as Australia/New Zealand - three flat pins)
Voltage
230V, 50Hz
Adapter Note
Most travelers will need an adapter unless coming from Australia, New Zealand, or other Type I countries. US/European devices will require both an adapter and should verify voltage compatibility.

Skip These Items

Heavy towels (most accommodations provide them, and they take forever to dry in the humidity) Formal wear or fancy shoes (Samoa is very casual, even nice restaurants rarely require more than smart casual) Too many clothes (laundry services are widely available and inexpensive) Snorkeling gear (easily rented locally if you don't already own quality gear) Bulky guidebooks (download digital versions to save weight and space)

Month-by-Month Guide

January

January sits squarely in Samoa's wet season, with warm temperatures and high humidity. You'll likely encounter afternoon rain showers and the occasional all-day drizzle, though it's still plenty warm for swimming. This is peak cyclone season, so worth keeping an eye on weather forecasts.

February

February continues the wet pattern with frequent tropical downpours, though they're often short-lived. The humidity can feel particularly intense this month, and it's still within the cyclone risk window. Tourist numbers tend to drop off after the holiday period, so you'll find beaches less crowded.

April

April represents a transition month as the wet season gradually winds down. You'll still get rain, but it's less persistent than the previous months. The humidity starts to feel slightly less oppressive, and it's a decent time to visit if you're looking for fewer crowds and don't mind the occasional shower.

30°C (87°F) High
23°C (74°F) Low
Typically 150-200mm (6-8in) Rainfall

May

May brings noticeably drier conditions as Samoa shifts toward its more pleasant season. The trade winds pick up, making the heat more comfortable, and rain becomes more sporadic. This is actually a sweet spot for visiting—good weather without the peak season crowds or prices.

30°C (86°F) High
23°C (74°F) Low
Typically 100-150mm (4-6in) Rainfall
Low Crowds
View Details →

June

June is one of the most comfortable months climatically, with lower humidity and minimal rainfall. The slightly cooler temperatures (relatively speaking) and steady trade winds make it ideal for outdoor activities. This marks the beginning of the preferred travel season for many visitors.

30°C (86°F) High
23°C (73°F) Low
Typically 80-120mm (3-5in) Rainfall
Medium Crowds
View Details →

July

July is peak dry season with the coolest temperatures you'll see in Samoa—though "cool" still means mid-80s. The humidity is at its most manageable, and rain is rare. This is prime time for hiking, snorkeling, and pretty much any outdoor activity, which means it's also when you'll see the most tourists.

29°C (85°F) High
22°C (72°F) Low
Typically 70-100mm (3-4in) Rainfall
High Crowds
View Details →

August

August continues July's pleasant pattern with dry, comfortable conditions and steady trade winds. It's another popular month for visitors, particularly families traveling during summer holidays. The ocean conditions are typically calm and clear, perfect for water activities.

29°C (85°F) High
23°C (73°F) Low
Typically 80-110mm (3-4in) Rainfall
High Crowds

September

September maintains the dry season's favorable conditions while seeing slightly fewer tourists as school holidays end in many countries. The weather remains reliably good, and you might catch some cultural festivals. It's an excellent compromise between good weather and manageable crowds.

29°C (85°F) High
23°C (73°F) Low
Typically 90-130mm (4-5in) Rainfall
Medium Crowds

October

October sees the dry season starting to wind down, with occasional rain showers becoming more frequent. The humidity begins to creep back up, though it's still quite pleasant compared to the wet season months. Tourist numbers drop off, making it a decent time for budget-conscious travelers.

30°C (86°F) High
23°C (74°F) Low
Typically 150-180mm (6-7in) Rainfall
Low Crowds
View Details →

November

November marks the transition into the wet season, with increasing rainfall and rising humidity. The cyclone season officially begins, though early-season storms are less common. You'll find good deals on accommodations, but you're trading that for less predictable weather.

30°C (86°F) High
23°C (74°F) Low
Typically 200-250mm (8-10in) Rainfall
Low Crowds
View Details →

December

December brings wet season conditions in full force, with frequent rain and high humidity. That said, the Christmas and New Year period sees an influx of tourists despite the weather, as people escape winter elsewhere. Expect tropical downpours, but also warm, swimmable conditions between the showers.

30°C (86°F) High
23°C (74°F) Low
Typically 300-350mm (12-14in) Rainfall
