During February,
weather in Hagatna is dry and sunny, it's a nice time for having lots of fun at the
Guam beaches. Most of the travelers prefer to travel from January to May to enjoy the pleasant weather in Hagatna. Even you can travel anywhere at Guam between Jan and May. Couple of years back, I visited Hagatna in the month of April, oh! I really enjoyed the places as well as the fabulous Hagatna weather.
Hagatna is a lovely city, especially the Paseo park & the Sirena park is worth a visit during weekends. Hope this helps and have a great time in Hagatna!
