Full Moon in Guatemala: Next Full and New Moon in Local Time, Plus the Meteor Showers

This page answers two questions for a night out in Guatemala, whether that is a full-moon hike, a dark-sky night at the lake or at Tikal, or a meteor shower: when is the next full moon and the next new moon in Guatemala time, and when do the year’s meteor showers peak.

The next full moon and new moon

Full and new moons for the next 13 months

Why the Guatemala date can differ from other calendars. The U.S. Naval Observatory (USNO) gives every phase in Universal Time. Guatemala keeps UTC-6 all year, so a phase in the first six hours of a UT day falls on the previous evening here: the full moon of 26 October 2026 at 04:12 UT is 25 October at 22:12 in Guatemala.

Every moon phase of 2027 in Guatemala time

The table above rolls forward from today. This one is fixed: the whole of 2027, from timeanddate.com’s 2027 moon-phase table for Guatemala City (read 26 October 2026). Each row is one lunation, numbered as the source numbers it, starting at a new moon. Dates and times are as the source prints them.

Twelve full moons. The table holds 12 full moons in 2027, from 22 January at 06:17 to 13 December at 10:08. Its 13th row starts with the new moon of 27 December; that row’s other phase cells are blank in the 2027 table.

Checked against the USNO. We compared all 49 phase times in this table with the U.S. Naval Observatory’s 2027 list in Universal Time (read 26 October 2026). Every one is the USNO time minus 6 hours (Guatemala’s UTC-6 offset) to within a minute: 37 match exactly and 12 are one minute apart. The November full moon shows why the date can change: the USNO lists it on 14 November at 03:26 UT, while timeanddate.com’s Guatemala City table puts it on the evening of 13 November, at 21:25.

Meteor showers, late 2026 and 2027

The International Meteor Organization (IMO) publishes an annual Meteor Shower Calendar with a working list of the showers, their activity period, the date of maximum and a zenithal hourly rate (ZHR), which the IMO defines as a calculated maximum number of meteors an ideal observer would see in perfectly clear skies with the shower’s radiant overhead. These are the IMO’s figures for the main showers from October 2026 to August 2027 (maximum dates as the IMO gives them, in UT):

The moon at the 2026 peaks. The IMO’s 2026 calendar says no moonlight disturbance will affect near-maximum observations of the October Draconids, the Orionids and the Leonids (the Orionid and Leonid maxima fall near first quarter), and that there is only a waxing crescent at the Geminid maximum. The same calendar says the η-Aquariid maximum occurs about four days after the full moon, and that conditions are also poor for the maximum periods of the Southern δ-Aquariids, the Aurigids and the Ursids. For the Ursids it gives the maximum on 22 December 2026 at 22h UT, two days before full moon; discussing a possible weak Ursid filament encounter earlier that day, it notes the Moon will be 96% illuminated and the chances for reliable optical data small. The phase table above gives the moon’s phases for any maximum date.

ZHR is defined for ideal conditions (perfectly clear skies, radiant overhead).

What this page is, and is not

• Phase times are instants. The table gives the moment of each phase, not a range of nights.
• No cloud forecast. For cloud and rain on a given night see the destination pages: Tikal weather (dawn cloud cover), Lake Atitlán weather and Acatenango weather (the night on the summit).
• Refreshed daily. Our pipeline reads the USNO list once a day; the next phase is picked when the page is built, and the stamp turns red if the list is more than three days old.
