February2026

Weather diary page

Feb 13, Guam: The dry season has finally arrived after a few false starts. Humidity today is down to 65% to 2PM. High of 30, low of 26, and very breezy.

Feb 22, Northern Rivers: Despite a 170mm downpour last Thurs night that typically tripled the max forecast, it still feels like the Great Dry switch might be on. It was dry before that - it's been dry since. Now El Nino is forecast to form, which means dry weather in Aus. Next summer could be a doozy in terms of fires - especially for southern states. Most days are around 30C with the odd 35C. It's hot but not excessive.

Feb 23, Guam: I learned this new phrase today -- shear lines. We have a shear line approaching. According to the news story:

Heavy showers are also possible as the shear line passes through. Aydlett said right now there is no expectation of widespread, sustained rainfall, but locally heavy downpours are not out of the question. "These shear lines can be kind of a wild card in the weather forecast," he said. "Sometimes they're light and drizzly in nature, and they persist for hours, or they can be locally heavy."

If showers do intensify as they approach, the NWS may issue short-notice flood warnings. But Aydlett said it is still too early to make that call.

Shear lines are a familiar feature of Guam's weather this time of year. They form as cold fronts sweep off Japan and Russia into the North Pacific, extending far to the south but losing their cold-front character as they enter the warmer tropical waters of the Pacific.

"Where those boundaries drop down and become somewhat stationary in the tropical, warmer waters of the Pacific, they lose that cold frontal characteristic, and they become these areas of shear, wind shear," Aydlett said, adding they typically occur every five to eight days from December through March.

Feb 28, NR: The pattern seems to be a spell of dry weather, then a huge downpour, though the dry breaks are getting shorter. Another 100+ mil on Feb 26-27. I really don't want any more coz i'm trying to sell, which is harder when the ground is saturated. Unfortunately, we're coming into the wettest of the various wet seasons here (only spring is reliably dryish). The big floods of '24 came on Feb 27-28, then Mar 28, so i'm hoping to at least get past then without any more massive deluges. Saw a baby wallaby come out of the pouch this morning - looked like it was one of its first ventures out. Had some guys come in who slashed, then baled the grass over the last two weeks, which makes the land look better for prospective buyers. Had to nag them to come back to bale it as they missed their scheduled time (piles of dead grass lying around in hot sun will burn/kill the grass underneath) - lucky i did coz the big rain came shortly after, meaning they would never have been able to do it if they hadn't done it before then. They have massive machines - i was amazed how fast they can do it. Only took two hours to slash the two back paddocks. Took three trailer loads of the grass to use as mulch, which will save some time weed-whacking but there must be some kind of bug in it coz ended up with some nasty bites on my legs.
