He said farmers still have low stock numbers from the bad drought two years ago but may need to reduce them even further.
"No one I've talked to has got a surplus of feed, so they're all just hanging in there. So if we get a hot dry patch, and it just goes off again, it could get a bit serious, or some people would have to make some decisions a lot earlier than they normally have to."
Galloway said it's a good time of year for farmers struggling with dry conditions to talk to their farm consultants and bank managers to make a plan for the future.
Unfortunately, it doesn't look like there's much relief in sight. Niwa has just released its latest seasonal climate outlook which shows most of the country will have higher than average temperatures over the next few months.
Forecaster Chris Brandolino said Hawke's Bay is in for a warm spring with below-average rainfall.
He said that's not good as soil moisture in the area is already unusually low.
"So looking at the spring season, we're really going to be watching that groundwater recharge. Unfortunately, we did not get as much rain as probably we needed or wanted, especially the central and southern Hawke's Bay region.
"We need the ground to get saturated to recharge the groundwater.
"Growing season is getting under way, whether you're growing kiwifruit or you're in the wine industry you want the groundwater to be there, but right now the whole water system is in deficit."
Hawke's Bay Rural Advisory Group chairman Lochie McGillivray said another dry spring and summer could push more farmers to sell into forestry as the carbon price is high.
"We've had a bit of rain but it's not enough. In some areas it's really dry - they're almost getting to a stress point, and with the soil being so dry that's affecting pasture growth.
"Some farmers who have had a couple rough years will be keen for the next generation to take over, some who have just taken over the reins will be wondering what the hell they've done and some will be contemplating selling to forestry."
McGillivray said with carbon forest companies paying above market value for land, the region was already starting to look different.
"Traditionally wonderful lamb and cattle finishing properties, that's gone into forestry. It's not the seller's fault, it's the kind of situation we've got with carbon at over $50 a tonne."
