The best time to visit Thailand is in the dry season—from November to April, temperatures are cooler and you can expect picture-perfect days for outdoor activities. The only downside is that it’s also Thailand’s peak tourist season. Flights and accommodation prices increase and the beaches on Phuket and Krabi will be full of people.
If you want to avoid the crowds, plan your trip to Thailand between May and October. While you will have to contend with often daily, short-lived rainstorms, you’ll be rewarded with cheaper flights and lower hotel rates.
Language:
The official language in Thailand is Thai.
Currency:
The currency of Thailand is the Thai Baht.
Credit Cards and ATMs:
In Thailand’s main cities like Bangkok and Phuket, you won’t have a problem finding ATMs and most businesses will accept credit cards as a form of payment. However, if you’re planning to go shopping at the local markets, you’ll need cash to pay for your purchases.
Plugs:
The plugs in Thailand are types A, B, and C. The standard voltage is 230 V, and the standard frequency is 60Hz. I recommend buying a universal adapter (make sure it has surge protection) and using a converter for hairdryers and hot tools.
Safety:
I consider Thailand to be one of the safest destinations for solo female travelers. While you still need to be aware of your surroundings, petty theft and tourist scams are usually the biggest things you need to watch out for.
